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:

  +--------------------------------------------------------------------------------------+
  |                             Loopback: virtual_keyboard                               |
  |                                                                                      |
  | +-------------------+      +-----------------------+    +--------------------------+ |
  | |MIDI / Logic piano |      |output channels: L & R |    | monitors: headphones     | |
  | | (Pass+Thru)       +----->+                       +--->+                          | |
  | +-------------------+      +-----------------------+    +--------------------------+ |
  +--------------------------------------------------------------------------------------+
  
  +---------------------------------+
  | Zoom                            |
  | +---------------------------+   |
  | | input: virtual_keyboard   |   |
  | |                           |   |
  | +---------------------------+   |
  +---------------------------------+

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.

thanks, I'll try that!
