I was working on a track a few days ago with a couple different synth plugins and I realized I didn't have any bass all of a sudden after I was done soloing a particular track in song editor. Took me a minute to realize the mod wheel position I had on the one basically dropped the low end out on the other.
It'd be cool in MIDI settings to be able to set the mod wheel position at a particular position and bypass it from receiving further inputs on that track only so it isn't changing on you if you're trying out different setting on a different track/plugin.
