Hi @zynthianers!
I’ve released a little kit for customizing the zynaptik module:
With this little kit you can add the extra features to the zynaptik module:
- 16 extra digital I/O pins (GPIO => MCP23017)
- 4 analog input pins (ADC => ADS1115)
- 4 analog output pins (DAC => MCP2348)
The software implementation is quite advanced and currently you can:
- Use the I/O pins as extra switches, assigning to CUIA or MIDI events
- Use the 4 analog inputs as CV, assigning to MIDI events (CC, Pitch-Bend or ChanPress)
I’m working for improving the CV/Gate implementation and very soon you could use the digital pins as Gate In/Out. The DAC (CV-out) remains unimplemented until now.
Take a look to:
I would like to not being the only one testing these features … 
Regards,
