Can someone help me figure out what the "midi channel" selector does on a "Polyphonic Expression" (MPE) subpatch? I made the following observation: if I set the midi channel on the subpatch selector to channel 1, it will react to midi notes on channels 2-16, and to midi cc on channel 1. This is what i'd expect.
If, however, i set the midi channel on the subpatch selector to channel 2 or higher, the subpatch won't react to any midi notes, not on channel 2, or elsewhere (unexpected!). It will react to cc's on channel 2, though (expected).
(all of this regards a main patch set to channel 1)
This is the end of my question.
And here's why i'm interested in this, if anyone has any other ideas:
I have an MPE keyboard on the USB port, and a regular midi keyboard on the DIN. I want to
have the patch react to program change messages from the DIN port (and preferably, but not necessarily, also the USB port)
have midi cc's from the DIN port ignored
controll a Polyphonic Expression subpatch from the USB port as usual, while
being able to toggle between ignoring or using addiotional midi notes from the DIN port
Towards achieving 4, i have constructed a subpatch that will resend midi notes from the DIN port, channel 1, to channels 2--16; that patch works fine, what i'm struggling with is getting the program change message from DIN, while ignoring the midi cc's from the DIN.
Any help is appreciated. Just in case, i'm including a the patch that i used for diagnostics.
