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.
