I made a PD project of a three steps clock with an adjustable option to send to Ableton live in order to create broken rhythm.

Is there a way to gauge the accuracy level of this cloclk?
Are there any interruptions possible for the accuracy of the clocl I've created?

@20har I suspect others know better than I, but haven't responded.

This is one way to test:

22-0721-realtime.pd

On my system, I observe jitter in "realtime" on the order of about 5 ms. This holds true at shorter intervals -- if I move the slider to 6 or 7 ms, I see the realtime number jumping between 5 and 10 ms (error within 5 ms, then).

I tried two different audio hardware buffer sizes, same behavior.

Up to 5 ms timing jitter doesn't seem very nice.

To sync with Ableton, I would use the abl_link~ external instead.
