Here is a simple, step-by-step guide to make your very own MIDI Clock to LSDJ and/or Nanoloop Sync Device.

This device will respond to 'STOP', 'START' and 'CONTINUE' MIDI real time messages, making it compatible with devices that are able to output MIDI clock messages. (eg. a drum machine or a sequencer). You can synchronise up to 6 copies of LSDJ and/or 6 copies of Nanoloop simultaneously to MIDI clock.
