You shouldn't have to sacrifice a whole channel, stick it in a table with a groove of 6/6 and run that on step 1 of a lightly used channel.

You could send/read once per 1/4 note by dividing the time by 24. whole notes by 96.... etc. It would work but gets less precise with fewer messages/longer time intervals. if the Aboy misses a tick, it starts to screw with the sync times.

Great idea!
but it's sad to sacrifice a channel and each step...

Do you think it would be possible to achieve the same thing, but once per phrase only?

what happend if the arduinoboy 'misses' a CC ?

Arduinoboy MidiOut send MIDI Stop and Start commands when a song is started/stopped, but the GB's processor is too busy to send to midi sync ticks at 24ppqn.
here is my workaround using an additional arduino w/ the appropriate Midi IN and OUT circuitry.

https://github.com/miotislucifugis/CC-t … clock-sync

One channel will have to be sacrificed and entirely filled (each step, of each phrase, for the entire song) with a X ?? command. (As-is, the sketch is looking for Ch 5, CC#127, val 15. Change these to match your Aboy editor settings)

This device reads the command, counts the time in between, divides it by 6 (24ppqn 1/4...so, 1/16= 6ppqn.) It then send 0xF8 midi clock messages at this interval until the midiStop message and CC messages end.
