    kallikak replied to a thread Filter Modulation in Audio Projects
    I have a very simple example here LFO Modulation that might help. It has an LFO modulating both an oscillator and a filter with an independent amount control as well. It doesn't use an envelope, but inserting one...

    You can daisy chain 8 MCP23017s off one i2c bus, giving 128 (interrupt capable) digital pins. That would support 64 encoders (if you're not using switches). And the Teensy 4 has 3 I2C busses, so you can support...
