    Teensy 4.1 and 120 DAC ?

    Hello everyone ,

    I come to you because I have questions.
    I'm working on a monophonic analog synthesizer project totally driven by midi. This project is progressing well, every day has its victories...

    However, eventually I want to make a polyphonic synthesizer, the initial idea was to make 6 synthesizers (vco/vcf/vca) and let the midi controller do the maneuver (note 1 on voice 1, note 2 on voice 2,.. .). Communication is carried out by USB between the midi controller and the synthesizer, which itself is driven in CV by a teensy 4.1 via 20 DACs (max11300).

    Now I tell myself that I could also multiplex a voice and the CVs to obtain 6 voices controlled independently of each other. However, I would then need 120 DACs (i.e. 6 max11300).

    Will the teensy4.1 be able to follow without too much latency and while maintaining correct sampling?

    cordially Jeremy

    Does it have to be all analog? You could use the audio library to implement 120 oscillators.

    Yes the entire audio path must remain completely analog. The CVs are there to manage the opening and closing of envelopes and filters such as the VcF / vca .
