Using the Z3TA+ in Sonar 7 PE - Patch selection issues

Hey guys,

I haven't used the bundled VSTs much with Sonar since I've had it as I had a lot of transferable experience with Reason synths, so was effectively using that as a beastly rack...

Anyhow, problem I've been having is that I wanted to run two separate patches separately and soon realised that I would need two instances of the synth.

Problem is, on the second instance of the synth, when I set up the channel, bank and patch in the corresponding MIDI track's I/O and hit the keyboard it's fine. But the second I press space or play, the bank on the synth itself keeps snapping back to Bank A (I need it on D)

Am I doing something wrong in the MIDI channel or synth...? I have the channel set to 1 of 16 on both instances. I'm assuming that Bank A, B, C, D, E, F relates to Bank 0, 1, 2, 3, 4, 5 on the MIDI channel...

Any help would be appreciated. I'm wading through the manual now as it's a very cool synth with great potential, but doubt I'll find the answer to my issue while I'm there :\

Thanks!
