While I also look forward to including Audiobus in Cubasis it’s limitations are becoming apparent.
It only has one output. So if one has midi tracks for two synth apps like Animoog and Addictive synth both feed the same output channel, with no mixer. Mix down becomes a series of run the midi, record the output, repeat for the next synth. Not that much better than copy and paste from the synths’ built in recorders.
