Exactly Steve. I want to be able to change arp mode (up, down, fwd assign, etc.), and a bunch of other things, on the fly. At this point I'm not trying to create or edit arp patterns in real time (though that may come later...)

I'm able to control most things in the preset that is in the edit buffer but now I'd like to tweak the other tracks, or channels, so I can have fun with  multi-mode. I'm not sure I understand the edit context. Do I have to modify the presets that are loaded on the tracks or does each channel represent its own edit buffer that keeps track of changes made to it? Sorry if I'm not explaining myself well.

Now I want to change parameters like the arp type on each multi-mode channel but I am not sure how to "target" the channel to make the change. The sysex guide refers to MULTI_MODE_CHANNEL_SELECT but when I select one then change a parameter, the preset on that channel isn't affected.

When you edit a preset from the front panel, you can edit the values on each layer seprately or all at once. So, let's say a particular preset has ROM Instruments on all 4 layers and you want the filter parameters and the filter envelope to be the same on each layer. You can change all settings for all 4 layers at the same time. Then, let's say you want to vary the filter envelope on two of the layers, you can do that. (At that point if I were editing a preset, I'd save it.)

For example, globally you assign MidiA -> MidiP to specific CCs. When CC values come in on a specific channel, the patchcords determine what those CC vlaues do. For example CC74 might control filter cutoff frequency on all layers of a patch on a specific channel. But it doesn't have to. Its all a matter for how you define (1) the CCs globally [eg, MidiA = CC74] and (2) the destinations for that source funtion [eg, MidiA -> FiltFreq +100).

Apparently these are immediately available via cc's on knobs A & B but I must confess that I don't understand which part of the voice these knobs hit - "All Layers" in the current preset, or some global filter? (Doesn't seem so based on what I'm seeing on the display.)
