The goal with this particular instrument is to handle the muting/mixing/panning of the N loops and the 1 dry signal.
Those aloop_in1 through aloop_in4 signals are coming in on their own channels, as is adry_in1. Is that what you mean? Then the stereo mix will be output to a left and a right channel before it goes to the output instrument…
Or do you mean bussing to the left and right channels directly instead of explicitly mixing them?
