Now that Roland made Roland Sound Canvas VA available for the Mac again, would be nice to have the option to use the vat or audio unit of it with QMidi. Especially to verify and play standard midi files.
Thanks for the info on using QMidi with MainStage, but I hope QMidi will implement the use of VST and/or AU in the future. Would make things a lot easier (especially now with the Roland Sound Canvas VA back on the mac).
The project have two tracks because I've tested the crossfade stuff (with 2 IAC busses).
The only problem right now with Logic is that it does not respond to sysex master volume messages, so crossfade cannot be done.
