@whale-av great suggestion, and thank you so much for your help! I'm on an old MacBook (2008) running El Capitan version 10.11.6. I'm on Pure Data version 0.49

thank you again!

I guess what I'm trying to say is that I can't get externals to work at all

Hi! I'm brand-spanking new to Pure Data (installed it yesterday) and I'm hoping to get some guidance. I've downloaded a patch called Ivertide that in theory acts like a harmonizer (Jacob Collier, Bon Iver) but I feel like I'm in way over my head. I've gotten to the point where upon opening the patch, the log window displays "soundtouch: can't load library", and sure enough, when I look at the patch itself there are a few objects (soundtouch, demux) that aren't valid. Is there anyone out there that can help me through this?
