Ripple effect sound when releasing sustain pedal

Hi Hans, thank you so much for looking into this issue.  Just to let you know, reducing the max poly has not fixed the issue. I tried reducing it to as low as 40, without success.

I want to use this setup as a simple stage piano. Your variant of samplerbox works perfect for me apart from that sustain issue.

I've done a bit more research around the sustain issue. The ripple effect only happens if the pedal is pressed down for circa 10seconds. Anything under that, the issue doesn't manifest itself. I found that taking the pedal off 5 seconds into a lead piano break and then back on reduces occurences of this ripple effect happening.

Why do i need the sustain on the pedal? 

I don't need it for all of the songs i perform, but if you think of a song like "Let it Be" that little piano run before the guitar solo is a must for the sustain pedal...and it works beautifully until i take the foot off the pedal!

If this is only happening when pedal is pressed for circa 10 seconds, it is as you say, a CPU or memory issue?.
Hans, is there any way in software to clear the memory buffer if it detects a long sustain keypress?  It would probably take a few mS to clear in memory and generate a click in the process but still, thats better than a rippling sound!
