Prologue-16 definitely doesn't like staying in tune until warmed up. Had lots of issues but firmware 1.10 fixed most.
I noticed LF comp. makes low volume static noise when nothing playing is that normal for a compressor? Guitar centers used section is pretty good for cheaper gear. I just saw a Prophet 12 module on there for $1300. Picked up a MINT used Roland TR-08 for $260. Not too bad in my opinion.
DavidDever you weren't by chance an oldskool trance DJ from Philly back in the day were you?
