Yes. But you have to set it up. With your synth in the AudioBus input slot and Cubasis in the output create a midi track set your synth to send midi and Cubasis to record it from the same channel. Make sure Cubasis created an audio track for the synth, if not create one and set it to receive from your synth in AudioBus. Enable recording for audio and midi set the time marker where you want to start. Switch to your synth. In the AudioBus launch panel hit record for Cubasis, jam away.
