The Garriton products work (I've got GPO and JABB), but there's one problem - BiaB sends a reset to the Mod wheel at the start of the song playback.

Unfortunately, Garritan uses the Mod to control the volume, so it sets the instrument volume to zero. This isn't an issue with instruments don't respond to the Mod wheel (such as the piano and harp).

You can get around this by embedding a Mod wheel instruction into the song playback. But that doesn't work if you use the "From" to play back the song, since it will skip the embedded MIDI instruction (assuming you placed it in the first bar).

Vocal control, you say. Never heard of it. Is that some kind of ProTools thing?
