Cool, thanks for starting the new thread. Oh, and thanks for asking questions that are really difficult to answer LOLOL!!
1. The Modwheel Situation
Even with the modwheel fully down, the EXS will generate sound internally when you play notes. But as you discovered, it then requires movement of the modwheel to some position other than zero to "reveal" the sound of the notes you played. Now... if you played a passage where you ended up with the modwheel being all the way up, Logic should allow you to pick up where you left off -- hearing the full-volume sound. If it's not doing that then you have to change your MIDI Chase settings, and possibly also change a few other things so that the modwheel isn't automatically set to zero when you stop playback. So first, please post back and let me know if that's what's occurring.
2. Which CC...
You can use almost any CC you like, with some exceptions:
- CC#7 is hardwired in Logic to control the channel strip fader
- CC#10 controls the channel strip's panpot
- CC#11 is hardwired in Logic to control volume in EXS-24 directly
There are other exceptions as well. But you should be able to choose, say, CC#2 - 9, 12 - 31, and so on, and not run into any conflicts.
Just a note that we have to be very clear when using the term "expression" if only because that's the official name for CC#11, but also, to distinguish it from what you're trying to achieve -- musical expression. And, as I previously explained, CC#11 has different [i]implementations[/i] in different plugins. I've already explained what it does in EXS. In Kontakt instruments it's very typical to find that CC#11 controls volume+filter (timbre). And then, in some instruments, CC#11 has no effect whatsoever. So when you say you want to use Expression in the hyper editor, know that what you'll be drawing in there will raise/lower the volume of the EXS sound just as you have it programmed. So for EXS, think of CC#11 as being an additional overall volume control.
You could also assign CC#11 to a knob/slider on your controller and record CC#11 data in realtime, but you can't use CC#11 to then control the filter in EXS (if you try to select CC#11 in the modulation matrix you'll find that it says "unavailable" or something to that effect). The same is true in EXS for trying to assign CC#7 as a modulation source.
4. Hyperdraw Display
I'll make this brief cuz I gotta run. But go into your key commands window and search for "hyperdraw: autodefine". Assign a key to it (mine is "H"). Now when you're in the piano roll, score editor, or even if you've selected a region, hitting "H" repeatedly will cycle the display through whatever CC data is contained in the region. (In fact, I just submitted a blog article on this which should appear sometime soon here on the MPV site).
OK, gotta run. More later on your modwheel situation.
