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.

Echolution 2 Build 78

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).
