Pigtronix Echolution-2 Deluxe - Manual (Page 19)

MIDI
Every function of the Echolution 2 can be controlled via
MIDI.
Setting the E2 MIDI Channel:
1. Power up the E2 while holding the LFO button
down.
2. Once the E2 has booted up, release the button.
3. Make your MIDI controller send a valid CC
command to the E2 (see table below), on the
desired MIDI Channel.
4. The E2 will pick the MIDI Channel of the first valid
command it receives, and store this for future use.
There is no need to repeat this procedure unless a
different MIDI Channel is desired.
Supported MIDI commands:
To load a particular preset, simply send a program change
command with the desired preset number. The E2 will load
that number plus one as the preset. This is because many
MIDI controllers send “PROGRAM CHANGE x-1” when you
select program x. ie. The foot controller will send
“PROGRAM CHANGE 00” when you select the footswitch
corresponding to preset 1. If you want preset 00, send 127
as the program.
