Hey Casper.

Try setting the max length again. I believe that should flush the buffer as the memory is cleared and re-initialised. To do it without flushing you could use LiSa as a delay. LiSa has a explicit clear function. Theoretically speaking that might prevent memory fragmentation and should have a lower performance cost (and you can ramp down before clearing to avoid clicks). In practice I seem to remember that clearing LiSa can lead to some performance costs too, though that might be related to my ongoing struggle with hard to detect floating-point de-normalisation issues.

Hope that helps,

Kas.
