with an aggregate device, if I join the mac built in output and black hole, what I get with [dac~ 1 2] is that it outputs to both devices at the same time. Maybe I'm configuring something wrong... ?

but the way Pd seems to work with multiple devices is that it splits channels for devices separately

I think the OS can do it on Mac (over a decade ago that I've used Macs,
but back then it was called "aggregate device" and you set up such meta
device which is composed of multiple soundcards. It exposes then the sum
of the inputs/outputs to the system).

I have no idea about the rationale not to include that function in Pd on
Mac, but I assume it's better if the OS is doing it. From what I
understood Apple is doing resampling anyway to compensate for clock
drifts, just like pipewire does on Linux.
