Hi John,
Thanks for your kind words.
Alas I couldn't read the mp3 (missed header?), but I think I reproduced what you heard.
I played several chords while keeping the pedal pressed, then released and heard the famous "clicks and plops" for which you invented the nicer term "ripple" - I'll add that to the clicks & plops FAQ (thanks and please also read that for another explanation of your problem).
What happens: the release keeps the sounds of all previous notes alive - so when using chords, a multiple of the notes.
When you release a CPU intensive process of reducing the volume of all these sounds starts in the sound module. This module works in a time slot and if the CPU can't chew all the work within that slot, then this can happen.
In my test (which I hope represents your situation) I noticed the CPU peaking in parallel with the "ripple".
So it's not so much a bug as you stated in your separate mail, but rather a limit.
If you intend to use sustain pedal in this way, you may avoid it by lowering the MAX_POLYPHONY in the configuration.txt.
I never tested this before as in my opinion playing with sustain pedal pressed over a longer period isn't a realistic way of playing as the sound gets messy - but your mileage may vary ofcourse.
If you want get a "non damped room" effect, I suggest to experiment with the reverb - this is quite powerful.
