OnClock drift test template

Post by saveas » 02 Apr 2014 08:42

Here is a template that highlights an issue with OnClock timing drift.
It sends midi note 36 on every 16th.
On my setup (iPad 3, iOS 7.04), running only Sunrizer on the background, I get high variation of time between beats (up to 100ms very often).

Is it a matter of iPad 3 not being capable enough to keep up with the clock or something else??

Ok i tested this with thor running in background and the max_variation after 500 beats was 0.025
But when switch to thor and doing some tweaks and then switching back max_variation went up to 0.200
Slaved to MidiOX max_variation was 0.040
