Sidechain SC3 issues
I'm having a few issues getting sidechain compression, specifically using SC3, working on OS X.
I tried a while ago with Ardour 2.7.1, and have recently tried again with 2.8.12 ($0 version, planning to pay after this issue is solved) and haven't had any luck with either.
Essentially, what I'm trying to do (in this instance) is ducking a piano track under a vocal track. I have looked on this site and others, and have set up a bus with SC3 (as well as a bypassed SC1, but that didn't help) and sends and inserts from the vocal and piano buses. I have tried almost every permutation of input channel for the key and varied the SC3 parameters to no avail.
The problem essentially is that SC3 seems to be ignoring the key input (and not really compressing at all, though I can't be 100% sure). The outputs also seem to be mono - the levels are the same for left/right, when the input levels are very different.
This is happening on OS X 10.6.8 Snow Leopard, with swh plugins 0.4.15 (the ones that come with Ardour 2.8.12). I haven't gotten a chance to try this project on a linux box, but I'd like to be able to do it all on the Mac. Any ideas?
Also, somewhat unrelatedly, I would appreciate it if anyone could point me to instructions on compiling LADSPA/LV2 plugins on OS X.
