8bit

This is a programmable computer with 8-bit audio output.

Functionality

  • It uses ATtiny1616 microcontroller which runs at 20MHz.
  • It's quite limited in terms of RAM, but it can be useful for creating audio sources and effects that require very little memory.
  • Has two CV inputs with attenuators.
  • Built-in low-pass filter to smooth out the audio output if needed.
  • MODE switch with LED indicator for implementing custom modes.

Inputs

Inputs

  1. MIDI MIDI input to control the 8bit module
  2. CV1 CV input for the first control voltage
  3. CV2 CV input for the second control voltage
  4. TX Debug pin for the microcontroller
  5. UPDI Programming pin for the microcontroller

Outputs

  1. MIDI MIDI THRU (passthrough) output
  2. AUDIO 8-bit audio output
  3. AUDIO 8-bit audio output (duplicate)
  4. GATE Gate trigger from the MIDI input
  5. GATE Gate trigger from the MIDI input (duplicate)

Controls

  • CV1: Attenuate the CV1 input if provided, if not CV1 input is normalized to 3.3V.
  • CV2: Attenuate the CV2 input if provided, if not CV2 input is normalized to 3.3V.
  • MODE: Toggle button to select the mode.
