I am looking at getting a 4-voice OB-Xa, what all is involved in upgrading it to 8-voice?

thanks

Unfortunately, it's not that easy or affordable. This pic is of my 8 voice. You can see the four voices right there, separated by those white things. Each voice is on one of those cards. Now look closer, you can see the second tray, with the other four voice cards underneath. I don't know if the four voice comes with an "empty tray", but basically you'll have to source and buy four working voice cards. Installing them isn't really complicated after that... so that's the good news!

Thanks! that is a great pic. I figured it would be something like that since each voice is basically its own card there.

I have spare OBXa cards and trays that I can sell, however they have no Curtis chips, so you would need to source them yourself which would be an expensive exercise, and then they would need calibration.

Yes, sourcing the boards, tray, chips and having it all installed/calibrated by a tech would be cost prohibitive. On another note, I see you're in a RUSH cover band and assume you're striving for authenticity with the Taurus and possible OBXa? I strongly urge you to reconsider bringing an OBXa on the road/to many gigs. It's insanely complex, sensitive and HEAVY. Please, do yourself a favor and at least try a Matrix 1000 module midi-ed into your MS2000. You'll get authentic sounds at 1/4 the cost and 100% less hassle. I love my OB but that's just my 2 cents.
