As a Digital Performer user, I want to caution anyone else to NOT buy the UAD plugs. The latency issue is crippling. They are virtually impossible to use without a nightmare of repatching, rebussing, and setting and resetting delay compensation pluggins. And you will NOT be able to record/track with them. They are essentially useless - except that you could strap them across the master bus at the very end of a mixdown. All in all - get Waves or T-Racks, trust me.
