Any progress on this? I would love to try this on my new PFM2.

All the voltage conversion is done by the hardware.
The firmware reads input at the MCU level (0 -> 3.3v).
The output comes from the DAC (0 -> 5v converted to -2.5v -> 2.5v)
As eurorack delivers -12v and 12v, i think it should be easy to amplify the audio output with a op amp in amplifier mode.
I have no plan at all to do that.
