So I have a musical pit gig coming up soon and am running some Garritan instruments through Logic Mainstage. I'd like to know if it's possible to make volume (or modulation) respond to velocity rather than just the mod wheel - through settings in ARIA Player, or in Mainstage, or perhaps through some plugin or other solution. When it goes into two hands material I can't really play and move the mod wheel simultaneously. (I've tried expression pedals, but they're very finicky and hard to control.) In an ideal world, I'd have separate control over sharpness of attack and loudness of sound, but for the moment I just need something that will work in a pinch.
Thanks in advance,
