Negative sustain with MIDI notes #24-#28 with specially crafted FXP

I recently discovered a Good Bad Bug/awesome quirk when messing with unison widths and damper duration. If you set the unison width to 0 and damping duration to 10, the strings become "perpetual motion engines", but only for MIDI notes #24-#28 using the Grimaldi harpsichord. To trigger the quirk, press a key within the aforementioned range, then press pedal CC #64 just after note release. If you hold the pedal too long, you get this:

---------------------------
Pianoteq 4.exe - Fatal Application Exit

Pianoteq Trial 4.5.0/20130411 fatal error [dkiI]: out-of-control[0],

OK

Honestly, I feel this is a really cool effect which could be used as a build up to a thunderous crescendo, however, when I consider the improvements a new generation model brings, the benefits outweigh this one simple bug. It would be better to fix it for Pianoteq 4.5.2+ or Pianoteq 5.
