sorry to hijack your thread, I have nothing to help you on this. Instead, I need some help with my setup and I wonder if you can help me! I started doing some remote piano classes. I have a midi controller and use Logic's piano. I want to play with 'local' latency, but still send the logic sound via zoom (or any other app). To do that today, I have to use an 'Aggregate Device', which introduces ~60ms of latency, making it super hard to practice. Did you face this problem as well?If yes, did you find a solution? Thanks!
If you use Loopback (and you may also use Audio Hijack for finer-grained control) you can create virtual devices that can be selected from within Zoom (for example) while being monitored through, say, a pair of headphones.
Here's a crude diagram that shows how this might work:
I believe this would reduce the latency from your keyboard to your monitors while any lag Zoom has processing the audio (and probably) video would be slightly increased.
