I recently picked this plug-in up, and it looks great, but when I add it to my Master Track in Reaper, it speeds up the whole project, to sound like chipmunks. While this was funny for a couple minutes, I really want to use this thing. :) Anyone have or hear of similar problems??
You decide your sample rate. In Reaper you set your project sample rate in Project Settings. Take a look at the top right corner and see which sample rate is using that project (48kHz, 44.1kHz, etc) and see if your sound card matches that.
