Dear Julie, I assume you’re planing to convert the patch to an Orac module. I fear I won’t be much help there, as I haven’t really used it and never converted a patch (maybe consult the organelle forum, there are some very nice and helpful people there). But if you need help making sense of the patch itself, send me a message with your problem and i’ll try to help as good as i can. BTW. I was planning on making a update of this patch myself, as there are tuning issues in the upper notes (Karplus-Strong-Synthesis is messy)
