This sounds like a very interesting project. Out of curiosity, are you using TouchOSC more as a patch editor or as a real-time performance tool?

If you use sysex, you are editing presets/patches. If you use CCs, you are doing something different. For designing sounds, I use the front panel (sometimes an editor) to create presets. Once created, I use CCs to tweak the presets for real-time performance.

"All layers" refers to editing parameters in a preset. Each preset can have up to 4 layers. 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.)

Each layer also has virtual patch cords (sources, destinations, amounts). Some of the sources are CCs. To use them, you don't use CC numbers directly; you use the source functions. 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).

Some CCs are defined by default (CC7 = Vol, CC10 = Pan, etc.) See http://launch.groups.yahoo.com/group/xl7/message/21532 for more details.

BTW, you might want to create preset templates that have patch cords set up the way you tend to use controllers. Just a thought.

Anyhow, I hope this makes sense and I hope it helps.

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.)
