Hello! Beginner in programming and electronics, I made a midi controller with an arduino pro micro, 64 pots 10k connected to 4 multiplexers 16 channels and 2 pots 10k directly to 2 analog pins. I used the example code supplied with the library and everything worked fine, but I noticed a bit of late…

The maximum rate that the Arduino's ADC can sample at (with full resolution) is 125 kHz / (13 cycles/sample)*. This is in ideal circumstances, when you're just constantly polling the ADC status register without doing anything else. If you need to sample 66 potentiometers at that rate, you get an eff…

I lowered the value of the analog filter as you indicated and that solved my problem. Thank you for your diligence and detailed reply!
