8 BIT

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 requires 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.

As of now, a 909 sampler is implemented as a firmware. More firmwares are in the works.

Inputs

  1. MIDI In
  2. CV1 In
  3. CV2 In
  4. Debug pin for the microcontroller
  5. Programming pin for the microcontroller

Outputs

  1. MIDI THRU
  2. Audio Out
  3. Audio Out
  4. GATE Out
  5. GATE Out

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.

Programming
