How likely is CV input expander to ever be made? Perhaps a 2 or 4hp expander which provides an additional 4 inputs? With a ton of possibilities in Mappings, I'm now finding that i could use at least 4 more cv inputs.

Not planned. But I understand that the CVM8 from expert sleepers seem to work well via I2C which means 8 additional inputs!

I can confirm that the CV8M works perfectly, right out of the box. You just change the little switches on the CV8M to put it in i2c mode, connect the little cable to the expander (it's included!) and route your signals to where you want in the nerdseq interface. It's great! 8 cv inputs in 4hp!

I got a CVM-8 and tried hooking it to my Nerdseq Multi-IO via I2C but could not get it to work. I had gotten my FR8 faderbank connected via I2C so was expecting to succeed. @rubberband, I was wondering if you had any recommendations.
On the CVM-8 I set the dip switches to 1101, which is the same as 1001 that you used but is for 0-10V instead of just 0-5V. I kept the pull-up resistor switch on the CVM-8 to off and didn’t make any other changes on the CVM-8.
I connected the CVM-8 I2C wires to port B on the Nerdseq Multi-IO and made sure that the wires were connected properly (gnd-gnd). I then configured on the Nerdseq the IC2 communication for channel B to be 16N->NS 17-32 so that the Nerdseq is a follower and should receive data from the CVM. I mapped port 17 so that I could see what its current value is. And then I connected a clock input to input 1 on the CVM. But both the CVM and the Multi-IO module communication LEDs never flash, and the Nerdseq Mapping page always shows a value of 0.
@rubberband, how did you configure IC2 on your Nerdseq so that it worked?
