The stand alone audio board and the prop shield are great, but...I'd love it if there was a board that had support infrastructure for all manner of audio projects, whether they be CV based, stomp box, or stand-alone instruments. Basically spots for the buffers, optoisolators, and DACs that accrue.
Ideally it'd have pads to support (*=eurorack version concessions):
One could argue that I should just switch over to the Axoloti, which has most of the I/O covered and a fairly slick GUI-to-finished-program process. OTOH: It's expensive in a per-board level and I like the control that the Teensy audio set-up offers.
I have poked around for teensy based projects with PCBs, and the closest I found is a partial match that isn't available anymore. Anyone have pointers for a better match, a PCB they've tested, or interest in designing something along these lines, with or without the eurorack safety/compatibility considerations? I'll get around to designing something eventually, but 1) probably not before the next version of teensy comes out, and 2) not without a lot of painful iterating on my part (I'm a doctor, not an PCB designer). Bonus: If there was a standard board that people were working with, it would decrease noob mistakes and enforce best practices, just as the other audio boards have.
Ideally it'd have pads to support (*=eurorack version concessions):
- MIDI in and out, with optoisolator
- Buffered audio in (ideally stereo)
- Stereo audio out, with and without amplification
- Connections for teensy ADC pins
- Buffered inputs for ADC *that can handle CV voltage range
- Buffered inputs for logic *that can handle typical gate voltages (up to 12V)
- Connections for DAC pin
- Dual outboard DAC *with op-amp for modular CV scaling (+/-5V or 0-10V)
- micro SD slot
- onboard memory
- barrel and *eurorack power connectors
