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.


When updating to the ver. 2.0 Echolution 2 application and firmware, you must update the firmware FIRST (using the old app) and THEN update to the 2.0 app.
If you update the app first, when you then update the firmware, the app will crash and disconnect.

If you updated the app first and can’t update the firmware, you will need to:
1) UNINSTALL the 2.0 app
2) Go to and download the Legacy E2 App (choosing the right platform for your computer: Linux, Mac or Windows)
3) Install the Legacy E2 App
4) Update the Firmware: click on File>Update Firmware in the app and navigate to the 2.0 firmware file (wherever you downloaded it to). The file is called “e2update.dat”.
5) Update the App: Go to and download the applicable app version, and double click on the file to install.

If you haven’t updated to 2.0 app and firmware yet, simply open your app and follow steps 4 and 5 above before you update the application to version 2.0.

MASSIVE firmware update and NEW application for Echolution 2

This new application and firmware allows expression pedal and envelope control of all knobs, simultaneously, with user definable heel and toe settings as well as independent envelope inversion, strength and decay time parameters for every preset.


The five main parameters (Repeats, Delay Time, Delay Mix, Modulation Speed, and Modulation Depth) now support independent mapping from the expression pedal and envelope detection circuitry.  The expression and envelope mapping can apply to multiple parameters, with each parameter having independent settings for Expression range/direction and Envelope strength/direction/release time.  When a parameter has any of these advanced mapping features enabled the LED for that parameter dimly illuminates to indicate the expression or envelope control.  The previous Single Expression/Envelope Mapping now serves as an Advanced Mapping Override allowing E2D users to quickly override or experiment without the use of a computer.

This functionality is easily accessed in the newly updated Echolution 2 application using the advanced options controls.  When a parameter is assigned expression pedal control, pointers for the heel and toe become visible around that parameter’s associated control knob; moving these pointers sets the range of control.  Controls in the advanced options menu set the direction of the expression pedal mapping.

Envelope control is also accessed through the advanced options controls.  Here envelope control of the individual parameters can be enabled, along with the strength of the mapping, the direction, and the release time of each.

This unprecedented level of control and tweak-ability is pushed to it’s limit with the application’s inclusion of Preset Blending.  Users can select two similar presets and have the application automatically set the expression pedal ranges and directions so that the expression pedal blends between the parameter settings.

To round out this paradigm shifting addition, we’ve added separate global settings for the Sensitivity and Release Time of Ducking, a host of improvements to Preset Management and Switching as well as access to Global Parameters (such as MIDI Channel).

New Features:

* Taps “teleport” when loading presets. This is helpful for seamless transitions between vastly different sounds.

* Switching in and out of TAPE mode is now silent

* Holding down rotary switch during boot sets MIDI channel.

* MIDI Bug that would see other MIDI channel’s data has been fixed.

* MIDI BEAT CLOCK output divider removed – This feature is essential for using E2’s tap tempo to control the Pigtronix Infinity Looper. 

This Echolution 2 firmware, combined with the Infinity Looper 2.0 firmware represents the complete realization of the musically synchronized echo, modulation, filter and looping system we set out to create. Enjoy!
