Question: how to use gvst-gsnap in audacity?
Answer: Select you clip, go to the Effects menu and click "GVST: GSnap". -The defaults are mostly OK, but the 3 main things you need to change are Key, Attack and Release. In fixed mode, click "Configure" and select the correct key. The Attack and Release knobs are how quickly GSnap will snap the note (in milliseconds).
