How to connect

Just connect the MIDI output of the controller to your TR-8oh8 modded TR-808. Adapters from TRS-A to DIN-MIDI are included with the controller.
Additionally, you can connect other MIDI devices to the controller via the MIDI input or via USB. MIDI messages coming into the controller are forwarded to the TR-8oh8.

Sending the current state

You might want to send the current position of the sliders and pots to your TR-8oh8 to synchronise them. In order to do so, press the ‘SEND ALL’ button for about 2 seconds.

Configuration

The built-in config menu lets you freely adjust LED colors and configure the way MIDI is routed through the controller.
To enter the config menu, press the CONF button. To exit, press it again.
Adjusting LED colors:
Use the pots above the Reslicer Repeat section to adjust RGB values for the repeat LEDs.
Use the pots above the Reslicer Random Jump section to adjust RGB values for the repeat LEDs.
Confirm LED colors by pressing the Random Jump AUTO button.
