I want to make a my arduino generate midi clock out of 2 midi outputs so i can sync 2 different devices to it and i want to control the tempo with a pot. Does anyone have any links to some good info on how to generate midi clock with an arduino or any advice at all? I have dealt with reading pots and converting it into midi cc before but its making a clock and what signals to send that is confusing the hell out of me.
Any help at all will be muchly appreciated thanks.
Generating MIDI clock is relatively easy.
I built a (somewhat) simple “analog-style” MIDI sequencer, which does transmit a MIDI clock signal. Schematics and source are available on my blog, which I’m going to link to below. If you just want a clock source, you’d only need the Tempo pot and the MIDI out wiring, and ignore all the other stuff 
The key thing is to transmit the byte 0xF8 to the serial port 24 times per quarter note. In my example, my notes are 16th notes, so I’m sending 6 clock pulses per note.
