MIDI8d is a simple yet powerful 8 Digital Outputs from a MIDI TRS input connection.
The core of the MIDI8d is the classic Arduino Nano.
Different firmwares (Arduino sketches) can be uploaded, to adapt or completely change the behavior.
Typical uses are:
- 8 Drums outputs, reacting to MIDI Channel 10 (notes 36 to 43)
- MIDI Clock ticks, with various time divisions and Start/Stop Gate outputs
