Hi list, In sigmund~.c line 228 / < https://github.com/pure-data/pure-data/blob/master/extra/sigmund%7E/sigmund%7E.c#L228 > Is that, int bin2 = (maxbin < bestindex + 50 ? bestindex + 50 : maxbin); should not be instead: int bin2 = (maxbin > bestindex + 50 ? bestindex + 50 : maxbin); I'm probably wrong, but in case, somebody could check?
