Strange glitch when using "Feedback Network" Max for Live device within Max 8

I recently was experimenting with some of the live device plugins that came with 8 (not sure if they were also in 7). The "Feedback Network" device is very interesting, but I keep getting this glitch where at seemingly random times there is an incredibly loud and distorted 7-note tune that plays (very tonal, unlike the feedback loops being generated), which has absolutely nothing to do with what's going on in the rest of the patch. I've isolated it enough to show that it is definitely being caused by this device (and it has to be connected to a DAC that is on). It's incredibly inconvenient for actually using the device in a live performance; sometimes it may not happen for 15 minutes and sometimes it may happen twice in two minutes. Has anyone come across this issue?
