E2 Firmware 101

The new E2 Pitch-Shifting firmware is now live.

This improved code will run on any version of the Echolution 2 pedal (Basic, Deluxe, Filter, Ultra). This is the standard firmware found in the new Filter PRO and Ultra PRO models which begin shipping on dealers this week.

To Update your Echolution 2, open the previous E2 application and select File->Automatic Firmware Update.

Once your E2 has been updated to firmware version 101, update the E2 Application by downloading and installing the new Windows and Mac OS X Applications.

Currently, Windows 10 is not supported.

Feature Enhancements:

Pitch Change (ascending and descending) for both delay taps.  Each delay tap can be assigned a different pitch shift interval. The pitch shifting can be turned on and off at any point using the remote switch JUMP function or via MIDI. Once a pitch shift value has been selected JUMP is automatically enabled, so that users without the remote switch can enjoy pitch shift effects. When a pitch shift value has been selected, the JUMP function “latches” and the JUMP switch must pressed again to turn the pitch shifting off.  Pitch Shift values can be assigned, saved and recalled in any of the 60 presets.

  • To change the pitch shift value for the first delay tap, hold down both the Delay Time (Short / Med / Long) and Taps buttons and turn the Preset Encoder to select the desired pitch shift value.  After simultaneously pressing Delay Time and Taps, (while at least one of them is still held down), the 7-segment display will show a number or “-“.  This number represents the Pitch change, The intervals are displayed as a number and decimal point; each number represents a corresponding scale degree (5 = perfect fifth) with the decimal point indicating whether that interval is flatted (5. = flat five).
  • The change the pitch shift value for the second delay tap, hold down the Special FX (Pong / Halo) and Taps buttons and turn the preset encoder
  • To change the VOLUME of the second delay tap, hold down the Special FX (Pong / Halo) and Taps buttons and turn the mix knob.
  • When one delay tap is turned on and a pitch shift value has been selected, JUMP with cause the delay to pitch shift.
  • When one delay tap is turned on and a pitch shift value has been selected for both taps, JUMP with cause the delay to alternate between the two assigned pitches (First Tap pitch for one cycle, Second Tap pitch for one cycle, etc).  The second tap will not be heard.
  • With two delay taps turned on, and a pitch shift value has been selected for only one of the taps, one delay will pitch shift and one will not.
  • With two delay taps turned on, and a pitch shift value has been selected for boths of the taps, each delay will pitch shift according to the selected intervals.
  • When FREEZE is activated, JUMP will only remain active for a single cycle, allowing material to change pitch one interval at a time.
  • When FREEZE is activated with a single tap but a pitch shift value has been set for both taps, the pitch shift value of the frozen delay will alternate with each press of the JUMP footswitch.

The Second Tap now has an independent Mix parameter.  This parameter decreases the volume of the Second Tap from the current Main Mix setting.  To Change the Second Tap’s Mix, hold down the Special FX and Taps buttons and then turn the Mix Knob.

When FREEZE is active, the Tap footswitch becomes Loop Record.  When FREEZE is turned on, pressing the TAP footswitch begin recording a new loop.  A second press (within 10 seconds) will close the loop and begin playback. To overdub, turn off FREEZE to add new material and turn FREEZE back on when done. Hitting the TAP switch will clear any currently looped audio. To record a new loop, make sure FREEZE is turned on and then hit the TAP footswitch.

When MIDI Sync’d, Tapping a new delay length, even using the Loop Record function, will quantize the new length to an integer number of MIDI quarter notes.  (IE, you can increase the delay time while remaining MIDI Sync’d).  To get back to the original delay time, quickly double tap the Tap Tempo switch.

Presets now load exactly as saved and ignore any expression pedal assignments until the Expression pedal has been moved.

Global Tap will not load the delay time of any preset saved with a SHORT delay range setting.  The previous Tap Tempo value will be stored and used once a delay without a SHORT delay range setting has been loaded. This allows musicians to access the myriad of modulation effects (that require delay times less than 100ms) while still preserving a global tap tempo when switching presets during live performance.

New Global Boot Settings:

MIDI Channel Selection Menu has been added.  Hold Preset during boot to access the MIDI Channel Selection Menu.  After the firmware version number has been displayed a ‘C’ will be displayed indicating the E2 will enter the MIDI Channel Selection Menu upon release of the Preset Encoder.

In this menu, users can see the current MIDI Channel selection and change it if necessary.  Upon entering this menu, the current MIDI Channel Selection will be displayed followed by a blinking ‘C’ to indicate the current menu.  The possible MIDI Channel assignments are 1-16 with tens indicated by an illuminated decimal point: 9 = 9, 0. = 10, 1. = 11, etc.  Turn the Preset Encoder Clockwise to increment the selection and Counter-Clockwise to decrement the selection.

Once the desired MIDI Channel is shown:

  • Pressing the Preset Encoder will confirm the selection, save the MIDI Channel assignment, and finish booting.
Phase Inversion Global setting has been added.  Hold the FILTER button while powering up the E2 to toggle stereo output phase inversion.  The Filter LEDs will indicate the current status of this setting while powering up.  Lit = Outputs are out of phase.  Not Lit = Outputs are in phase.
Delay Output Boost has been made toggleable.  Hold the TAPS button while powering up the E2 to toggle the delay output boost.  The Taps LEDs will indicate the current status of this setting while powering up.  Lit = Delay Output Boost.  Not Lit = No Delay Output Boost.
Added Non-Pitched MIDI Tracking (Taps  will Teleport when a New MIDI Tempo is received), this is a Global Flag and can be toggled by powering up the E2 while holding down the DELAY TIME button (Short, Med, Long).  The Time LEDs will indicate the current status of this setting while powering up: Lit = Pitched MIDI Tracking.  Not Lit = Non-Pitched MIDI Tracking.
MIDI Clock Thru has been added to Boot Settings.  Hold Special FX (Pong / Halo) while powering up the E2 to toggle the MIDI Clock Thru.  The Pong / Halo LEDs will indicate the current status of this setting while powering up.  Lit = MIDI Clock, if present, will be copied from MIDI IN to MIDI OUT.  Not Lit = MIDI Clock will not be copied from MIDI IN to MIDI OUT.
MIDI Thru has been added to Boot Settings.  Hold the LFO button while powering up the E2 to toggle the MIDI Thru.  The LFO LEDs will indicate the current status of this setting while powering up.  Lit = MIDI data other than Clock, if present, will be copied from MIDI IN to MIDI OUT.  Not Lit = MIDI data other than Clock will not be copied from MIDI IN to MIDI OUT.
Dry Kill During Bypass has been added to Boot Settings.  Hold down the Trails / Listen / Dry Kill button while powering up the E2 to toggle Dry Kill During Bypass.  The Trails / Listen / Dry Kill LEDs will indicate the current status of this setting while powering up.  Lit = Dry Kill will remain active (muting analog pass-through) when the E2 is Bypassed.  Not Lit = Dry Kill will disable (allowing analog pass-through) when the E2 is Bypassed.
Generate MIDI Out Clock has been added to Boot Settings.  Hold the Reverse / Duck button while powering up the E2 to toggle whether the E2 generates MIDI Clock from its current delay time.  The Reverse / Duck LEDs will indicate the current status of this setting while powering up.  Lit = E2 will generate MIDI Clock from the current Delay Time.  Not Lit = E2 will not generate MIDI Clock from the current Delay Time.

Pigtronix launches Pitch Shifting Echolution 2 Multi-Tap Delay Pedals at Summer NAMM


July 9, 2015 (Port Jefferson Station, NY) – Pigtronix unveils two new masterpiece delay pedals at the Summer NAMM in Nashville today: Echolution 2 Ultra Pro and Echolution 2 Filter Pro.

Both new E2 models feature Independent Pitch Shifting on two syncronized delays, which can be overlapped or set to numerous rhythmic configurations, including the Pigtronix signature Golden Ratio function. The tap tempo and MIDI-controlled dual delays can be set to pitch-shift by any musical interval within an octave. Sweeping filters and complex modulation options—with up to 5 LFOs—create new sonic textures that go far beyond the “shimmer” and “crystals” effect patches of the past.


The Echolution 2 Ultra Pro (E2U) replaces the E2 Deluxe. This new flagship delay processor represents the ultimate realization of the Echolution 2 platform, providing an unprecedented level of parallel delay and filter processing in a pedal format. Breaking away from the industry-standard “one sound at a time” paradigm, the Echolution 2 sports 30 individual front-panel algorithms that can be selected in any combination, deep expression pedal and envelope mapping options available via real-time MIDI or PC/MAC app control.

The E2 Ultra Pro ships with numerous firmware enhancements over the original Echolution 2 Deluxe, as well as a double-digit preset indicator—eliminating the need for bank selection—and an improved USB port for connection to the editor software. In conjunction with this firmware and hardware upgrade comes an enhanced PC/MAC editor, which gives this monstrously deep time machine free access to even greater depth of customization.

The Echolution 2 Filter Pro (E2F) replaces the E2 Basic, adding on-board multi-tap / tap sub-division control as well as 8 different filter options and pitch-shifted time based sound effects. These core “pro” features give players who want a streamlined user interface the ability to tweak key delay ingredients on the fly. Connecting the pedal to the free Pigtronix Echolution 2 PC/MAC editor application via the newly revised USB port gives the E2 Filter Pro access to the full power of the flagship E2 Ultra Pro.

Many of the new sounds, MIDI functionality and deep sound design features found in these new units were requested by Pigtronix Echolution 2 users around the world and can be added to previous versions of the Echolution 2 via a simple online firmware update process, as detailed on the Echolution 2 blog located here:

The new E2 pedals will ship worldwide in August, 2015 and will hit the street at $449 USD for the Echolution 2 Ultra Pro and $329 USD for the Echolution 2 Filter Pro.

Pigtronix bass pedal trio reviewed by Bass Guitar


The UK’s Bass Guitar Magazine plugged into all three Pigtronix bass pedals and weighed in.
Bass FAT Drive: “A tube sound is the basis of the drive tone, with that recognisable warm softness at the core of the various sounds you can coax out of the unit… with the tubey sound of a wholly accurate representation of the noise made by the old glowing valves.”
Philosopher Bass Compressor: “A rather impressive pedal that offers a range of useful options.”
Bass Envelope Phaser: “a gizmo that adds ‘the funk’ to your bass sound in a seriously powerful way that no words con the printed page can possibly describe.”

Infinity Looper review in MusicTech

MusicTech Infinity

MusicTech magazine checked out the Infinity Looper and published an excellent review.

Here’s an excerpt:

“The Infinity Looper is an excellent bit of kit that definitely brings something new to the looping table. The ability to record synchronized dual loop audio from separate sources and run the unit via MIDI means it’s a real looping solution for bands. The 24-bit/48 kHz recording spec means the unit sounds great, so it’s very hard to tell the difference between live and looped playing, and recordings are virtually noise-free. While you can get into the unit’s basics pretty quickly you do need to study the manual—thankfully this is well written and the information is easy to access. The Infinity has a well laid out and fully featured interface and all the right sorts of connections to make it an extremely musical, practical and flexible solution.”

Pigtronix Infinity 2.0 Official Release: Build 202

Infinity Looper is officially out of BETA. The 2.0 firmware is rock solid and contains numerous new features that have been requested by Pigtronix customers around the world!

The easiest way to update your Infinity is to connect it to your computer via USB, run the Pigtronix-Infinity application, Select “Tools->Update Firmware” from the menu bar, Left-Click the “Automatic” button, close the application, disconnect the Infinity from your computer, and then Power Cycle the Infinity while holding “INPUT SPLIT.

The Infinity Looper 2.0 firmware file can be downloaded for manual install here

The Windows application has been modified and can be retrieved by running the “UpdateApplication.bat” script in the PC folder of the Infinity’s USB drive.  Further directions on updating the application can be found here.

The Mac OSX application has been updated and can the new installer can be downloaded from here.  Download and run the installer.  On newer versions of Mac OSX it will be necessary to Ctrl + Click the installer to get the necessary installation permissions.

Release Notes:

Fixed issues that could cause the Infinity to crash if left running for more than 3 hours.

In Sync’d modes, Loop 1 can now be erased and re-recorded to its previous length.  When re-recording Loop 1, it will automatically close at it’s previous length: maintaining synchronization with Loop 2.

Added Double-tap instant Overdubs to Sync’d Parallel, Series, and Fade / Trails modes.  When a loop is waiting to begin playback, pressing that loop’s footswitch again will cause the loop to enter overdub mode when it begins playback.

Added Per Preset Default Sample-Rate.  Using the Infinity Application, users can now select a default sample-rate for each preset (48 kHz, 24 kHz, 12 kHz).  Whenever a preset is loaded, or both loops are erased, the Infinity will reset to the selected default sample-rate.  This allows users to record loops, alter their timing / pitch using Varispeed, and after erasing everything, instantly be at a known sample-rate.

Added support for Extended Multiplier selections via Infinity Application and MIDI CC 82.  Using the Infinity Application, or a MIDI CC, the multiplier can be set to any value from 1-127.  When set to values other than indicated (x1, x2, x3, x4, and x6), all Multiplier LEDs will illuminate to indicate that a custom multiplier is selected.  When a custom Multiplier is set, pressing the Sync Multi switch will move to the closest non-custom setting (x1, x2, x3, x4, or x6).  To set a custom Multiplier, send the desired Multiplier value on MIDI CC 82, or set it using the Infinity Application by selecting “Custom” and entering the desired multiplier in the box.

Added Global Boot Option for Overdub Synchronization.  With Overdub Synchronization enabled:

  • If no MIDI Clock is applied, Overdubs will only open and close on Loop Boundaries.
  • If MIDI Clock is applied, Overdubs will only open and close on the downbeat of measures as set by the Time Signature Setting.

This setting can be enabled using the Infinity Application’s “Tools->Global Boot Options” and selecting “Sync OD to MIDI / Loop Boundaries.”

This setting can also be toggled using the Infinity’s Boot Option system.  When the Infinity powers up, it will display the setting of Overdub Synchronization on the 5 Sync Multi LEDs; these will be illuminated if Overdub Synchronization is enabled.  To toggle this setting, press and hold the Sync Multi Switch while the Infinity powers up.

MIDI Time Signature Support.  The Time Signature of a provided MIDI Clock can now be sent using MIDI.  This feature allows Beat Buddy users (and users of any device that supports the sending of Time Signature), to dynamically adjust and then save the Time Signature of the Infinity.  This has been explicitly tested with the latest Beat Buddy firmware.  When the Beat Buddy changes songs, it will send a new Time Signature to the Infinity.

Reverse buttons (MIDI and Remote) now toggle the reverse request.  Previously the Reverse could only be cancelled by pressing the UNDO switch.

Fade and Trail stop modes now save currently open overdubs.  Previously leaving an overdub open when a Fade or Trail stops a loop

Changed behavior of Overdub: If an overdub is closed and undone in a single cycle, attempting to open an overdub will wait until the next loop cycle before actually opening the overdub.

When transitioning between Loops in Series, pressing stop will now stop playback correctly.  Arm stop cancels the transition.  All stop cancels the transition and stops the currently playing loop via it’s selected stop mode.

Fixed an issue that caused All Erase to not work when MIDI Clock was applied.

Fixed LED Flickering when used with MIDI.

Infinity 2.0 Release Candidate 4: Build 156

Here is the firmware for the Infinity Looper 2.0 Release Candidate 4.

Global MIDI Settings for Beat Buddy: MIDI Start Plays and MIDI Stop Active.  Combined with the previously added MIDI Start Records, all aspects of the Infinity’s response to MIDI Start and Stop commands can now be customized.

  • MIDI Start Play enables playback of recorded audio when a MIDI Start is received.  This Playback begins according to Arm/All and Parallel/Series settings.
  • MIDI Stop Active enables instantly halting all playback/recording when a MIDI Stop is received.  This stops both loops instantly, regardless of Full/Trail/Fade and Arm/All settings.
  • The defaults for the Infinity are MIDI Start Rec=Disabled, MIDI Start Plays = Enabled, MIDI Stop Active = Enabled.

Infinity Looper can be reformatted on boot up. New menu allows the user to select the number of presets / maximum loop time: 

  • Pressing and holding the SERIES LOOPS switch while the Infinity boots (directly after the firmware version number displays) will enter a Reformatting Menu (indicated by a lower-case ‘r’).
  • In this menu, users can select the number of presets to format the Infinity with, in increments of 10: 1=10, 2=20, 3=30 etc.
  • Once the desired number of presets is shown:
    • Pressing on the Preset Encoder or the SERIES LOOPS switch will confirm the selection, reformat the Infinity, and reboot.
    • Pressing the STOP footswitch will cancel the re-formatting and exit the menu.

Infinity Looper now has MIDI Channel Selection menu to display and change the current MIDI channel assignment:

  • Pressing and holding the STOP MODE switch while the Infinity boots (directly after the firmware version number displays) will enter a MIDI Channel Selection Menu (indicated by an Upper-case ‘C’).
  • In this menu, users can select which MIDI Channel the Infinity listens to.  The possible MIDI Channels are 1-16 with tens indicated by an illuminated decimal point: 9=9, 0.=10, 1.=11, etc.
  • Once the desired MIDI Channel is shown:
    • Pressing on the Preset Encoder or the STOP MODE switch will confirm the selection, save the MIDI Channel, and finish booting.
    • Pressing the STOP footswitch will cancel, exiting the menu without making any changes.

Quickly changing presets via MIDI is now more stable.  MIDI requests for preset change are now ignored while a preset is currently loading.  Once that preset finishes, only the most recent preset change is processed.

MIDI SysEx message handling has been optimized.  

MIDI CC implementations for all the soft-switches (STOP MODE, INPUT SPLIT, SERIES LOOPS, etc) are fixed.

Changes to Varispeed setting via Pitch Up/Down/Center made before recording audio are now saved.


 The easiest way to update your Infinity is to connect it to your computer via USB, run the Pigtronix-Infinity application, Select “Tools->Update Firmware” from the menu bar, Left-Click the “Automatic” button, close the application, disconnect the Infinity from your computer, and then Power Cycle the Infinity while holding “INPUT SPLIT.

This update includes additional Global MIDI settings accessible via the application.  The Windows application has been modified and can be retrieved by running the “UpdateApplication.bat” script in the PC folder of the Infinity’s USB drive.  Further directions on updating the application can be found here.

The Mac OSX application will be released early next week.  The Previous application will continue to work with this firmware without the ability to change MIDI Start Plays or MIDI Stop Active settings.

Guitar World gives Rototron its Gold Award

Guitar World took Rototron for a spin and decided it deserved their esteemed GOLD AWARD.

gw sq

A lot of pedals—from phasers and vibes to so-called rotary effects—approximate the sounds of a rotating speaker cabinet, but it’s rare that one can nail the sound, performance and quirks of the genuine Leslie cabinets used to great effect on recordings by the Beatles, Peter Frampton, Stevie Ray Vaughan, and many others. The Pigtronix Rototron is the latest contender, and it comes much closer to the authentic experience of playing through a Leslie cabinet than any stomp box yet.

Most rotating speaker pedals sound good, but I don’t know of any that perform as close to a genuine Leslie as the Rototron. The overall effect is thick, warm and chewy, with an unmistakable combination of phase shifting, chorus and tremolo that replicates the true Doppler effect of a rotating speaker. The ramp and brake effects are the coolest, and they expand the pedal’s creative potential beyond the usual swirling and gurgling underwater sounds. The rotating speaker effect sounds dead perfect and uncannily threedimensional when each output is connected to a separate amp. All that’s missing is the squeak of a poorly lubricated motor.

Here is the firmware for the Infinity Looper 2.0 Release Candidate 3.

No changes were made to the applications since Infinity Release Candidate 2 (build 152). The Applications can be found here (PCMac).

Instructions for updating the firmware and applications are located here.


-Series Mode Beat Buddy support has been finalized.

-Issues related to pausing a Beat Buddy during record have been corrected.  NOTE: Pausing the Beat Buddy while recording a loop will break synchronization, causing the Infinity to begin quantizing actions on loop boundaries rather than measure boundaries.

-Reformatting using the SERIES LOOPS switch at boot now immediately loads the reformatted settings.  Further, switch presses during boot no longer alter loaded settings.

-Errors related to Auto-Zero Record have been fixed.

Infinity 2.0 Release Candidate 2: Build 152

Here is the firmware for the Infinity Looper 2.0 Release Candidate 2.

The Updated Applications can be found here (PCMac).

Instructions for updating the firmware and applications are located here.


-Complete Beat Buddy support has been thoroughly tested and fixed where necessary.  All incidental delayed behavior has been removed and the Infinity’s currently armed loop can be set to record (if it has no recorded audio) when a MIDI Start is received.  This setting is under “Tools->Global Boot Settings->MIDI Start Records.”

-An issue caused by starting the MIDI Clock at the same time a MIDI Start is sent has been fixed.  NOTE: To accurately track all MIDI Clocks, the Infinity requires MIDI Clock signals to be present for up-to 1-minute, without changes, before accuracy is guaranteed; starting recording via MIDI Start as soon as the MIDI Clock is enabled can result in degraded synchronization performance.

-Issues with UNDO/REDO and Overdubs in Series Mode with the Trail and Fade Stop Modes have been fixed.

-Trail and Fade modes now react to Double-Tap Full-Stops.

-Additional Wear-Leveling has been added.  The Infinity now randomizes the location of Blank Canvas on start-up (where possible) to increase the life of SD Cards and significantly increase stability.

-Color-Blind LED indication has been disabled by default in this build.  It can be re-enabled using the Infinity Application.  This setting is located in “Tools->Global Boot Settings->Color Blind Mode.”

Echolution 2 Build 78

Click Here to Download the latest firmware for your Pigtronix Echolution 2 and Echolution 2 Deluxe.

New Features:

  • Maximum delay level has doubled. The Mix Knob can make the delay 6dB louder at the maximum setting.
  • Adjustable Filter Cutoff Frequency for the default filter, LP filter, and Tape filter.  Each preset can have different settings for each of the 3 filters.
    • To Change the corner frequency of the currently enabled filter, Press and hold both the Filter Selection and Bypass Selection Soft Switches, and then turn the Speed knob.  Immediately after updating your Echolution 2 the filters will be set to the finely tuned defaults: Default = Fully CW, LP = 11 O’Clock, Tape = 9 O’Clock.  Any changes made to these settings can be saved to the current Preset using the Preset Encoder.
    • To change the corner frequency of the currently enabled filter using MIDI, send the desired (0-127) value on MIDI CC #74
  • Global Tap option sticky flag.  With Global Tap enabled, the delay time will not be loaded when changing presets.
    • To toggle the Global Tap setting, press and hold the TAP footswitch while the Echolution 2 is powering up.
    • NOTE!: The Remote Switch assignment sticky has moved to the ENGAGE Footswitch!
  • The Echolution 2 now copies ALL data from MIDI In to MIDI Out.  If a MIDI Clock is present on MIDI In, it is copied to MIDI Out.  If no MIDI Clock is Present on MIDI In, the Echolution 2 will output its own MIDI Clock on MIDI Out.
  • Ignore the Incoming MIDI Clock option sticky flag has been added.  This can be used to control multiple Echolution 2’s via MIDI CC’s but allow them to have different delay lengths.
    • To toggle the IgnoreMIDIClock setting, press and hold the Expression Assignment Selection (EXP) while the Echolution 2 is powering up.
  • Changes have been made to the Echolution 2’s Power up procedure:
    • The Echolution 2 will now display “-” while it initializes itself, when this is done it will display the current firmware version number in a sequence of three digits.  For this firmware you will see “0->7->8″.
    • While the Infinity is displaying the current firmware version number it will also display the current settings of each sticky flag
      • Global Tap is displayed on the TAP LED:
        • Not Lit = Global Tap is disabled
        • Lit = Global Tap is enabled
      • The Remote Switch setting is displayed on the ENGAGE LED:
        • Not Lit = The Remote Switch controls Jump/Freeze
        • Lit =The Remote Switch controls Preset selection
      • The setting to Ignore Input MIDI Clock is displayed on the 5 Expression Selection LEDs
        • Not Lit = MIDI Clock is NOT Ignored
        • Lit = MIDI Clock is Ignored
  • 2 new special values have been added to the Engage MIDI Controls.  These new values explicitly assign the current Engage State
    • MIDI CC #27 Value of 3 explicitly sets the Echolution 2 to Engaged
    • MIDI CC #27 Value of 4 explicitly sets the Echolution 2 to NOT Engaged

Bug Fixes from previous versions:

  • Tap Tempo, Engage, Jump and Freeze MIDI Controls have been fixed and now correctly allow a value of 1 to trigger a short press in ALL cases
  • Jump and Freeze are now ignored if the Delay Range is set to NO DELAY (If the Delay is turned off using the Delay Time Soft Switch).  This prevents the Echolution 2 from staying in the Jump or Freeze state until the Delay is turned back on.

Infinity 2.0 Release Candidate: Build 150

Here is the firmware for the Infinity Looper 2.0 Release Candidate.

The updated applications can be found here (PC, Mac).

Instructions for updating the firmware and applications are located here.

Here is the final manual. PLEASE read it.


-New MIDI CCs for Incrementing or Decrementing the currently selected preset

  • Decrement Preset (MIDI CC #85, >=64 decrements)
  • Increment Preset (MIDI CC #86,  >=64 increments)

-Sync’d Series Mode can now close loops early while remaining sync’d (as Parallel Mode does)

-Close Base Layer->Overdub via the Undo Footswitch now also respects early loop closures in Sync’d Modes.

-Loop Volume EXP Mapping and behavior of the Loop Volume Knobs has been fixed

-Preset Encoder long holds no longer change with sample-rate

-A few small bugs with Pitch Intervals, MIDI Program Changes, and MIDI Song Select have been fixed.


Both applications have received numerous bug fixes related to saving and loading audio and Set saving/loading.

Bass Musician magazine reviews the Philosopher Bass Compressor

Bass Musician magazine has given the Philosopher Bass Compressor a rave review:

“I’ve used many different compressors, some good, some bad, but none like this. If I was to only have one pedal in my setup, (I currently have three, a chorus, fuzz, and preamp), this would be the pedal. Why? Simple to use, but still does a lot, even though it is “only” a compressor. The five basics on this pedal are volume, compression, sustain, a toggle switch for grit, and lets not forget the engage toggle switch for on/off functionality. I’ve used the Pigtronix Philosopher Bass Compressor on a couple different gigs, one in a small club, and the other at an outdoor festival. I couldn’t have asked for more, as the pedal fit everything I needed. With the compression and sustain, I was able to actually turn my chorus off, as I only use a small amount just to “round” out the notes a little. With the grit function, I was able to remove my fuzz pedal, and still get the amount of dirt I needed. The grit function of this pedal is one of the features that make it different from the other compressors on the market and gives a subtle distortion that really stands out.

The volume knob is just that, and the compression knob goes you a blend of both dry signal and compression. Lastly, the sustain knob goes from very subtle sustain to practically hanging on forever until you chose to stop it. One thing I noticed with the sustain, unlike other compressors, especially at the festival is that it did not affect notes played that I did not hang onto, it only applied sustain where I wanted, evenly, and until I let it go. Increasing the sustain also gave me affect if I held the note long enough, I got a small amount of feedback, which I really liked, especially at the end of a tune. Keep in mind, I was outdoors, and my rig was fairly loud. For the small club gig, I did use the supplied 18 volt adapter, and for the outdoor festival, I just added it to my pedalboard and connected it as 9 volt. I did notice a small difference in the operation between 18 and 9 volt, but nothing that really stood out or even seemed to affect the performance of the pedal. The  Pigtronix Philosopher Bass Compressor is really making me rethink my current setup and could easily replace two of my current pedals. Click to listen to some of the audio samples and you may end up doing the same.”

Infinity Build 143: New Features and MIDI Bug Fixes

You can find build 143 here and directions for updating the Infinity’s firmware and applications here.

This update is the first feature-complete firmware update.  In this update we’ve resolved the final remaining issues with MIDI Synchronization, added support for changes to the Default Blank Canvas settings, and more…

This update is the final feature update for the Infinity Firmware.  We will stay in BETA while customers report any remaining issues and while we prepare even more documentation.  Following this final BETA stage, we will release the Official Infinity 2.0 firmware.  Thanks for working with us throughout this process.

List of NEW Features:

- In Series Mode, when using the Fade Stop Mode, switching between loops no longer causes the current loop to fade.  When a loop is stopped using the Stop Footswitch the loop will fade out as it does currently.

– Infinity now accepts MIDI Program Change messages to change presets.  This can be disabled in the Application by going to Global Boot Settings and unchecking the “Accept Program Change” check box. The MIDI Song Select Command can still be used to change presets.

-The default Blank Canvas settings can now be changed using the updated application.  To change the settings simply select the Blank Canvas from the Preset List and make the necessary changes.  Audio still cannot be loaded to, or saved from, the Blank Canvas.

-We’ve added MIDI support for the alternate Remote Options (Stutter, Erase, Erase+Rec) and Expression Pedal Mappings (Aging, Varispeed).

  • Stutter: MIDI CC# 48, Values 1-127 trigger
  • Erase: MIDI CC# 49, Values 1-127 trigger
  • Erase+Rec: MIDI CC# 50, Values 1-127 trigger
  • Varispeed: MIDI CC# 3, 0-127
  • Exp: MIDI CC#4, 0-127
  • Aging: MIDI CC# 9, 0-127

MIDI Bug Fixes:

– All remaining issues with MIDI should be resolved.  In particular:

  • Using Varispeed with MIDI no longer causes incorrect pitch changes on playback.
  • Auto Zero Record has had 24kHz re-enabled by default.
  • Fast Tracking has been enabled.
  • MIDI Start no longer causes MIDI Timing glitches.
  • MIDI Sync in Series Trail/Fade modes no longer experience occasional glitches that caused delayed actions.
  • Changed implementation of Reverse and Undo MIDI CCs to allow Remote-like control that can enter AND exit Varispeed etc.  These CCs do obey Stutter, Erase, or Erase+Rec settings.

Rototron wins Guitar Player Editors’ Pick Award


Guitar Player magazine has given Rototron its Editors’ Pick award in the October 2014 issue.

Here’s an excerpt: “The Rototron sounds superb through a single amp, and utterly divine through two. It captures that multi-dimensional rotary speaker sound extremely accurately, while being capable of some trippy and ethereal sounds when you get creative with the knobs. The Rototron’s tone is rich and lush throughout its range, and the control parameters offer sky’s-the-limit flexibility that behooves much exploration… for tone, flexibility, and sheer inventiveness, the Rototron earns an Editors’ Pick Award.”
