Anyone using Jupiter 80 with cubase?

trying to confirm what i believe is the midi , audio routing. which looks very limited.

i think you can use an external midi keyboard and send no more than 4 separate midi channels in to JP 8 , one for each part.

it looks like you can only send two independent stereo tracks into your daw.

is the sub out TRS or TR?

should i try and use usb for audio in to cubase, Does it just mirror the main audio, or is this a way to get a third independent audio track?
