#39520 — setTimout iteration causing lag

My midiplayup solution in sequenser that use setTimeout is causing lag, should i try to come up with some statistical algorithm to resolve it or should i use buffered playup and will that playup work with simultaneous recording and keyboard playback?

Which route should i take change the playup or doing some statistical adjustment?

I really can't find any examples of buffered playup so i really do not quite understand how it work, i guess there is a buffer with intervals in PPQ where most is empty and it somehow send messages on some of them?

If so what is the PPQ "resolution" that generally fit the buffered approach?

Statistics or buffers, need some advice here?

I suspect setTimeout is not causing any lag unless you are trying to use a value less than 10:

No i am pretty sure it is not related to any screen draw "and i think draw use different timespann then note rendering i am pretty sure draw use interval in 1/24 th of second see setting. And the timeout is a different process, but anyhow you can use checkboxes to turn of  any rendering it will still lag.
Piano Notes Canvas
Draw key press
Scroll time/bar
But then again i can be wrong and missed something.
