I use panning and pan plug-ins for numerous tricks in my music. I love the 80s UI in Audio Damage’s Panstaion. It’s a pseudo recreation of the Drawmer M500. $39.
“Panstation is, without question, the most sophisticated autopanner plug-in available. We started with a loose model of the venerable Drawmer M500′s panning engine, then added the counting features from the Audio & Design PanScan (probably the most famous vintage autopanner, and the “secret weapon” of many well-known producers.) The result is an autopanner plug-in that is second to none in both feature set and sound.” – audiodamage.com
