Cubase Mixer issues

[MBTC]

Have you looked at the Cubase Tutorial (available from the question mark on the plugin)? I believe it's covered there.

I have a Snow which only has two outputs and up to 4 parts, so I can't do the same things I might with a TI Desktop, but the way I use it is typically using one instrument track for the plugin and one for the audio output, and bouncing everything from that point on. I only expect good polyphony from one "epic" sound at a time out of the Snow.. maybe I could do more, but if I use multiple parts I tend to just use them to beef up the single sound. If I added a desktop I might aim for 3 sounds for the 3 analog outs, in which case I would set up a bus like stereo 1, stereo 2, stereo 3 and make sure the audio track is mapped to that bus, then a MIDI track to hold the notes/automation for each part.

At least I think you said you have a desktop or keyboard model? The plug in is a bit different between that and Snow.
