Awesome idea: use Pi Pico as USB sound card + DSP! Equalizer, crossover, room compensation, etc.

So here's where the project sits at the end of day 1 - It's a #Blackberry Q10 keyboard working through a #PiPico #RP2350 controller. I'm making a physical keyboard case for my phone because I'm outrageously tired of virtual keyboards.
That's a PMOD implementation of the Q10 keyboard by Solder Party (shout-out to @arturo182) - I don't think you can buy these anymore but I bought two of them years ago and squirreled them away for the day I'd have a suitable microcontroller for the project.
