When using heavy pad style sounds on the polysix emulation, and a note is stolen, the emulator seems to ignore the filter/attack settings, and just plays the note with the filter fully open.

    Not sure if this a bug or normal behaviour. It has been open for ages now so it might be difficult to get an example patch to test it out.

    The note stealing operation should result in a 'key-re-on' flag being set, this tells the envelope to return to the attack state however per default it will not return to zero but start the attack from the current value. There are issues with a 'rezero' of the envelope which is if you have a fully open envelope and quickly rezero the value to start another attack then you will invariably get clicks and pops which is why they default to a continue mode on the current gain.

    So, if the envelope is typically fully open, which may well be the case for pads where you want to have the sound swell up and maintain itself rather than have percussive entrance then this might be the normal result.

    Having said that, pretty much everything you report does turn out to be a bug which is why an example patch might help.

    Regards, nick

    My bad. I was evidently jumping to conclusions when I posted this. IIRC, I was using patch 23 on the polysix. I think I mis-took the filter being completely open when playing new notes for note-stealing. Attached should be a fix for that memory that just lowers the release on the filter when a key is released.

    Am not convinced it was your bad - you have a knack for finding issues with bristol. I might put this on to pending for the next release, if it comes up again later we can reopen.

    This is probably normal behaviour then. :P

    I wouldn't call it a knack really, if I come across something in one of the emulators that makes me go "Hm, that doesn't sound/look right", I'd subsequently report it!

    As a side note though, perhaps this bug squished somehow in the later releases....

    This is being closed as unreproducible. If it comes up again, and it may, it can be reopened or another case can be made.
