I am a Pro Drummer and also own and run the band pa. I just traded my Ber. 2500 in on the new XTi 4000 and wish they would release the software for it. I have JBL and two 15" sub's. I want to trade my JBL JRX 115 for two more JBL JRX 112m. That way I would have four of them. Two for mains and two monitor's.
