_LIMIT & PAINT issue?

[Dav]

I'm working on a keyboard recording/playback program - will post it soon.  Had an issue with _LIMIT when used with the PAINT command.   Basically I'm using _LIMIT to control the speed of the recording and playback, and allowing the user to control the _LIMIT rate to speed up/slow down song playback speed. 

Roughly something like this...

speed = 100

DO
   _LIMIT speed * 10
  .... allow use to adjust speed value from 40 to 200 
  ...PAINT a key played...etc..
LOOP

Well, it worked sometimes, then not at all -it will get to a point that _LIMIT won't change anymore and stayed on one speed no matter what the speed variable is.

After much bug testing and eliminating lines, I narrowed it down that the PAINT call was the culprit -- when I replaced it with a LINE that does the same thing, the _LIMIT change always worked as it should.  Put PAINT back in, it fails. Any idea what could be causing the PAINT/LIMIT to clash? Perhaps my graphics system is the problem?

Anyway, _LIMIT is working fine using LINE command, so I'm beyond the hurdle now, just wondering about it still...

My guess is PAINT is slowing the main loop to the point where LIMIT can't compensate.

Remember that LIMIT auto adjusts.  It'll compensate to a certain point but if the loop in which it resides is too slow it will not be able to auto adjust.

Thanks , @NOVARSEG. Yeah, that's probably the best guess.

Anyway, the program is working and I hope to post it soon.
