Sorry for the delay. I just checked it after updating to the dev branch and editing the pru file again to enable the muxer with the CTAG Beast. Good news: the 64 and 128 block sizes are now available and the patch builds and runs without errors! Thank you so much!!
Now I just can't get it to recognize voltage from non–X.0 pins. So the patch prints expected values for voltage going into 0.0, but not from 0.1 — same with 1.0 vs 1.1, etc.
It works with both the Pd multiplexer-capelet and the multiplexer-display examples, so I imagine I just need to tweak something in the patch. My patch has the array named bela_multiplexer, I'm using indexes 0-63, the muxer is enabled in the IDE and the pru file. Is there anything I'm missing?
