I mainly want to know if you believe what I'm trying to do is possible before I spend a lot of time trying to do it. I'm a relatively new Linux user but I'm learning.

I'm a bedroom producer. I have Tascam Model 12 (12 in, 12 out) and Expert Sleepers ES-9 (14 in, 12 out) audio interfaces. I would like to combine them into a single device driven by ALSA (PulseAudio is incompatible with VCVRack, my preferred "DAW"). Furthermore, I want the Model 12 to occupy IOs 1-16 (with 4 dummy IOs) and the ES-9 to occupy IOs 17-32.

Currently, the generic ALSA device can handle one or the other interface, but not both at once.

Any hints toward a solution (e.g. how to start crafting an aggregate interface) would be greatly appreciated!
