MIDI Manual

The LinnDrum MIDI mod allows your LinnDrum to send and receive MIDI information whenever drums are played. It also generates or syncs to MIDI clock and handles MIDI start, stop, continue and song position pointer. In addition, the mod supports MIDI disk drive saves and loads.

Setup mode:
Set the Setup switch on the MIDI interface to ON position. Now, pressing down on any of the drum buttons will display the note value that is assigned to that drum. While holding the drum button down, press Right arrow button to increment or the Left arrow to decrement the note value.

Note that on power down, the note assignments will revert back to the factory default settings.

To Slave the LinnDrum to MIDI Clock and Song Pointer:

Set the Setup switch to the ON position.

Pressing the Left arrow will make the LinnDrum to be behind the beat.
