Re: EDP hardware (2 EDPs)

I am still owing a mail about this to the list.
I must admit that I did not find the beautifull solution yet.

Thats it. I have a double pot that does this at once, simple to build 
into some device like a stereo effect machine after the 2 EDPs, case 
you dont use a mixer like me.

If you have pages on your MIDI pedal, you can make one for each 
purpose, put the EDPs on different channels and have one page send 
two notes, one for each channel.
Other methods are to send only on one channel and have a Sysex key 
that changes the MIDIchannel of each unit or switches Control source 
to make them receptible.

Unfortunatly I dont see how to use presets for this since they are 
channel specific.

>d. Separate controls for EDP #1 & EDP &2 separately, but in the same patch

This is a bit more complex, because there are functions that you want 
for both EDPs simultaneously, even if you operate MONO. This is 
mainly FB and MUTE. Ok, you can switch to c to control those, but for 
example you may want build on one theme while the other is fading, so 
you need to have the FB of one unit reduced while you overdub over 
the other. So on my MIDI unit, i will have FB for both EDPs 
separately, and for

fun idea!

Yes, but its not huge and it depends on how the panning happens exactly.
