Thanks Surfer
I was mainly asking about being able to record midi from the synth as opposed to audio. Im aware of audiobus and its ability to record audio tracks - although ive never tried it. It looks worth it just for the ease at which you can switch between audio apps.
But still, im not clear as to whether I can record midi from a synth app into cubase? Note data to begin with, but hopefully various other parameters once automation is in there. Basically, I want to be able to play on my synth keyboard and twiddle the knobs, while having Cubase record all the midi data.
