"I'm using a rack system, composed of two Oberheim DPX-1 sample players, which play Mirage, Prophet, and Emulator disks. I've also got a rack-mounted DX7, a Roland digital piano module, a Roland Super Jupiter module, and a Roland DP-5 multi-effects unit. It's all controlled by a Simmons computer mixer, which has about 64 programs in it. Through that mixer I change all the MIDI channels on all the modules. I control the mixer through a Roland MIDI MKB-200 keyboard controller. You can assign split points to the keyboard, so I do that for a lot of songs where there is, say, a piano, a koto, then a trumpet sound. Rather than take an Emulator and things like that on the road, I wanted a very easy live setup, so that I could do most of the work beforehand. That's another reason for having those two Oberheim sample players. An Emulator disk takes a long time to load, and you can't say, "Sorry, Madison Square Garden, I've gotta load this disk." We've worked out a system where we can keep switching back and forth [between the DPX-1s]. The only other alternative would be to use something like a hard disk, which I don't really want to do because the hard disk has to be installed in the Emulator and is notoriously unreliable on the road. The good thing about having a rack system is that it can be well protected. You can throw it off the back of the truck and nothing will happen to it."more
I acquired my DPX-1 from the then manager of Swan Yard Studios just as they were closing back in 2002, it had been used on countless recordings in the 80's and 90's along with an Akai S900 i bought and an Oberheim Matrix 6r none of which i own today. The DPX-1 was a sample player expander which had SSM filters, it was basically an Emulator II playback engine in a rack.
