Run with 24 frames and a frame size of (needed buffer / 24).
Run this with sched fifo, etc...
Output 24 frames of silence.
Write some more silent frames (it wont be accepted before one is free), send
MIDI event for each. [Gives the MIDI device time to sync]
Write a frame of real data. Send MIDI event. Repeat.
This would give you some jitter but the MIDI device should filter that.

Hi all,
I'm trying to hack up a quick app that sends MIDI clock pulses in sync
with a ringbuffer playback.
I've got it reading MIDI (thanks to Matthias' great exmaple code), but I
cant figure out how to send MIDI clock pulses explicitly. The ALSA seq
interface lets me set it up to go automatically, but I want to send a
clock pulse every 1/24th of the buffer, so the sync is correct.
How about dividing the buffer in 24 frames. And send one MIDI event each
frame? Doable?
