I'm having trouble using more than two instances of a VSTi with Cubase SX 2. The same problem arises with Garritan PO and in EWQL Silver Edition. You are supposed to get 16 unique channels with every VSTi, but if i have four instances, with 8 channels each, then the third and fourth instance interferes with the first and the second instance. Some MIDI messages gets received by both. I have no trouble having different instruments assigned to the channels, playing them, and so on. But if I have volume changes during the song, on the 17th channel (the first channel on the third instance), the 1st channel (the first channel on the first instance) will also get that message, and adjust it's volume. Anyone have any idea what this might be?
