I've had a Matrix 6 Keyboard version for many years but have never heard the M1000. I was at the Vintage Synth Explorer website http://www.vintagesynth.com/oberheim/mat6.php and read this comment by

"Fantastic sounding dirty beast, massive sounds, amazing programmability, slightly slow envelopes but to be perfectly honest not every synth fits all holes, this is an underated classic but i have to point out its got a much more analog sound than that of the matrix 1000, they are supposed to be the same, but those wide bodied CEMS and the sightly odd way its clock pulse behaves compared to that of the 1000 makes them worlds appart imo."
Just curious if anyone else has noticed that, because it could definitely influence the decision.
