OBERHEIM SYNTH

Hello,

Had 3 m1000 at once .. fantastic synth !
i agree with the previous comment 2 in stereo with voice spillover
and a dedicated multiFx a la tc m300 or an mpx550 .. is a pure sonic heaven
Now i have only one after i got a Jupiter6

never heard a m6 but FIY from
(both use the cem3396 from the schematics)

Matrix 6 & 6R /// Matrix 1000

Both Matrix use six CEM3396 'Synth on a Chip', M6 has wide body version (600mils), M1000 
the small (300mils) one. Both Matrix synths have DCOs. Master clock is derived from a 
quartz on the Matrix 1000 and from three free running, software calibrated (voltage 
controlled) oscillators on the Matrix 6.
M6 has a 4 to 2 split mode, the M1000 lacks this hardware, otherwise the voices are 
(nearly) the same.
6 CEM3396 Dual Wave Processor (Withe body?)

old definitiion: Matrix 6 and Matrix 1000 differed in the way that the M6 had a couple of 
Curtis chips to generate a voice while the M1000 used a "synth-in-a-box" chip from Curtis 
that had the whole voice in one IC. Even the "Wave" selection feature was packed in there. 
I only don't know if Curtis developed this chip because Oberheim wanted them to do so. So, 
if someone wants to build his own analog synth, he might start with that chip. It's not 
the best sounding chip but very easy to build control circuitries around it. On the web, 
you might find interesting information about SSM and CEM chips.
