A couple of weeks ago I scored an Oberheim Matrix-6R on eBay. I’ve had a Matrix 1000 before, but we never became friends. It sounded too much techno and too little vintage. Therefore it might sound strange for me to go and buy a Matrix-6, since their guts are nearly the same. The thing that convinced me was the video review by my favorite Japanese guy, Katsunori UJIIE. He really brings out the nice brass and strings this machine is capable of!
Since I live in Europe and bought it from the US (the rack version is quite hard to find in Sweden, I’ve been looking out for one for a while), I turned to a guy I know to convert it from 110 V to 230 V. I read on his blog that the built in PSU can be switched by doing something on the inside. I didn’t ask him exactly what, but for someone that’s good with electronics, doing the mod should be piece of cake. I suspect it’s something simple like repositioning a wire and changing the fuse.
When I got it back I plugged it in and was amazed by it’s sound! Fantastic brass presets, perfect for a brass guy like me. Compared to how I remembered the Matrix 1000, this sounded like something completely different. Maybe it’s the combination of more vintage sounding presets and the fact that the DCOs on the Matrix-6 aren’t controlled by the same clock.
Compared to the Roland MKS-70 that took two rack units, and really deserved them, the Matrix-6R definitely deserves its three rack units! I still have a JX-10 that has exactly the same guts as the MKS-70, but honestly, I think I like the Oberheim sound better! The JX-10/MKS-70 with their 24 DCOs are technically more advanced, but they are flirting too much with the digital trend of that time. I also find the Oberheim snappier and the filter more characteristic. To sum it up:
Roland JX-10 / MKS-70
• 24 DCOs
• Roland chorus
• Slow envelopes
• Digital sounding presets
• Broken midi/sysex implementation
• Vintage sounding presets
• 12 DCOs
• 3 rack units (compared to MKS-70 2 or Matrix-1000 1)
• Slow CPU, lots of sysex chokes it
