Can it be turned to a cv to midi interface?
No. You can’t turn a DAC into an ADC
Darn… Oh well… Learned something today. It would be possible but with another hardware design, it’s not just the softwear right?
No it’s not just the software.
That’s a bit like saying, can I turn a TV set into a recording device
But you can use speakers as (bad) microphones.
Or headphones, I used to do that when I had my first computer sampler.
…and, you can make sound come out of a dynamic mic, if you plug it into an output.
I wouldn’t recommend it, though.
