When performing on stage, we have a problem keeping all our MIDI instruments in time with each other. So I need to create a master sync source. This would be a box which can send a MIDI ‘Start’ command when a button is pushed. It would be nice if it could synchronise this start command with the first beat of the bar so the music never skips a beat.

I decided this would be a good project for me to get back into microcontrollers. It’s been about six years since I’ve done any microcontroller work so I’m a bit out of touch with the latest in that field.
