After making my first few sound boxes with axoloti, I was rapidly in search of having a maximum amount of knobs at my disposal.
I’ve used the midi standard (by using off the shelf midi controllers, or by making my own using a teensy board or the Touch Board by bare conductive) but I would really like to use the 12 bit resolution that the axoloti offers.
I’ve tried understanding multiplexing by following these forum threads :
for ADC (inputs) :
for DAC (outputs) :
But I get very easily confused my the amount of multiplexer chips available and the ways to assign them in the patching software.
So here are my questions :
What is an easy way to get a maximum (and what is the limit) of analog inputs and outputs from an axoloti core board ?
Is there not a way to use a teensy board (that offers 21 analog inputs) and communicate with axoloti via serial port (instead of reducing to 8bit and converting to midi protocol) ?
Is there any other way ?
