I was trying to use volume pedal as a "send" to (X+MOD+)DLY+REV.
So I put the volume pedal "after stack".
then main output to "master stereo" feeding a stereo PA
and monitor out to "stack" feeding another loudspeaker
but when I use pedal no sound come out.
I can understand the possibility to use the volume to control the post stack sound.
But it wouldn't be useful (and easy to implement i suppose) to have also a volume pedal position let's say after X slot or MOD ?
