I just tried it again in Sonar 7PE. The DXi version will change bank and patch from the MIDI track assigned to Z3ta+. The VSTi version will change patch, but not the bank. It shows in the MIDI track as being changed, and it shows the correct bank and patch name. But Z3ta+ changes only the patch, not the bank. Every patch is from Bank A, regardless of what the MIDI track shows.
Very strange, and apparently not a problem for most people. Is anybody else seeing this behavior?
I just use the DXi version to avoid this.
Thanks.
