The third deep dive video on the Zoxnoxious synth covers the hardware bus and how the backplane communicates with the each of the six voice cards. I describe what functions happen via digital protocols such as I2C and SPI. I also show how the voice cards are setup and how each voice card accesses analog outputs from other voice cards.
The analog VCOs and VCFs are kept in tune with an autotune routine. Showing how this is done with frequency measurement and linear interpolation is detailed as well.
