Finalizing my first prototype USB Midi Controller with Leonardo and heading over to PCB, enclosure etc.
I then thought to add some built-in audio interface 16/24bit with 2 stereo outputs. Searched but didn't find useful info. Anyone has done something similar or any ideas ?
One "stupid"/easy way would be to mount some USB hub inside the case (to power/connect both), then connect to the hub the Arduino and probably find some USB sound card to plug. But wonder if there some kind of shield or other way.
