Just a side project. It's not unlike the OPL2LPT or the OPL2 audio board, but I would like to use the real hardware. Driving such an ISA card seems simple enough for an Arduino. Far from it. OPL2/3 does not have to deal with data transfer, latency, etc. An ISA sound card with an OPL2 is super easy …

You would be also making software that would support the usb sound card? I would write the software to drive the ISA sound card as an USB MIDI device (for the OPL part) and maybe USB audio device (for the digital audio part). The hard work of implementing these specs is already implemented by …

Hey! I would like to turn a real Sound Blaster Pro (CT 1600) into an USB sound card (using an Arduino for example). The card needs +5V, +12V and -12V. I was wondering if I would be able to power it just from the +5V of an USB port to avoid an external power supply. Does anyone know how much current …
