I'm having trouble with lop~ getting stuck putting out NaN. Is there a workaround, like filtering out the NaNs before and after lop~?

only happens sometimes, but once it gets stuck, it stays stuck.

(OS X pd 0.39-2)

thanks,

Roberto

I saw something about this on idecibel.fr, sorry I can't find the link but my guess is that it's an intrinsic problem. Therefore change your patch, look out for div by 0 anywhere up the chain and try adding a few DC blockers [hip~ 1].
