Hello! I am trying to make an interface for an analog polyphonic synthesizer and I want to have a lot of CV outputs coming from the teensy. I know 24 channels might be impossible, but thats my goal. I guess right now I have two plans. either one big multi-channel DAC, or a bunch of dual or quad dacs. Is there any insight into how hard this is before I go deep down the rabbithole?
I am currently using a Teensy 4.0
I am wondering if there was any reason that this 16 channel 16 bit DAC wouldnt work with the teensy? It communicates via SPI at 50 Mhz. I know teensy 4.0 CPU speed is 600 MHz so maybe this would work?
Ive also thought about using a bunch of these MCP4822 - dual 12 bit dacs They also use SPI.
I'm not sure exactly how to interface with them correctly, but I have seen this person's blog post where they do something similar with 6 of the MCP4822's controlling a synthesizer
Or maybe i could use a whole handful of these single channel 12 bit MCP4725. They communicate via I2C .
