Just talked to my wife and she said UPS delivered the ZOOM MRT-3 drum machine to the house.. Can't wait to get home and play around with that thing.. I'll be getting back with a review of it and how well it syncs with my PSR..... I still have yet to get a midi cable for it.. The only one I have is one that hooks up to the midi in and out of the PSR and to the joystick port of my computer.. Hmmm could I use that chord? It has midi in and out plugs, but also has the gameport connection.. Will it transmit data if I just use the midi in and out????

Zoom makes great drum machines. I have an RT-323 myself, and I use it all the time. Its only problem is that it won't do 8th note takt (7/8,9/8, etc.) but the sounds are exceptional, and it is very easy to program (compared with, say, the DR-770)
