Crumar BIT DCO clone with added functionality

video upload by Craig Barnes

"This dual DCO is based on the counter/resistor ladder technique used in the Crumar Bit series of polyphonic synthesizers, the 8253c triple counter has been replaced by a Waveshare Zero RP2040 based SOC. This allows the Waveshare to receive MIDI and calculate portamento etc. The only thing I want to add is an interval for DCO2 to set things like 5ths up in the DCO pair. Each DCO currently has 4 waveforms, Saw, PWM, Triangle and SUB. Although I might reduce that down by removing a triangle and SUB from either side. It was designed as a DCO core for a monosynth or a poly depending on needs."
