OBERHEIM SYNTH

Thanks a lot, pal. Very useful info !! Yet, a less clinical sound would be welcome, anyway..... Is there a lack of chorus on M1000? I think it would be a great option. It's often implemented on the greatest synths ( I own an Elka Synthex, one of the best choruses ever made on board..), since it changes the sound dramatically. Don't know anyway if it would be hard to be implemented on a 1 rack unit machine.
Btw: the "ring modulation" attempt would be great, one of my favourite options...
Cheers,
Francesco.

       I don't quite follow this
 per-voice argument. Everything that happens in software
 (LFOs, RAMPs, ENVelopes etc.) is per-voice basis. Every
 signal that is generated in software is calculated
 separately for each voice, and the signal generation code is
 virtually identical to M6 (and 6R), so no hidden secrets
 here. The only exception is global Vibrato that is
 'shared' between voices. Everything that happens in
 hardware (OSCs, VCF etc.) is one-chip-per-voice anyway.
 
 
 Another myth that has been
 circling around for at least 25 years is about the wide body
 CEM3396s versus narrow body ones. And it has been debunked
 for a zillion times. I think even Doug Curtis himself
 commented on this long time ago (or was it Dave Smith?)
 saying it's not true. The only difference soundwise
 comes from timer clock circuitry: while on M1000 all timers
 are driven by CPU clock M6 has three separate LC oscillators
 resulting in less 'clinical' clock and some minimal
 drift that is usually perceived as 'more organic' or
 'phatter' sound.

       Sorry.
 
 I remeber now that probably each CEM chip has a resonance
 and cutoff section on its own... Am I wrong? So the less
 organic sound on the M1000 is an issue of the "narrow
 body" Cem instead of the "regular sized" CEM
 found on the Matrix6. Or maybe a digital control of the
 filter on the Matrix 1000 makes them to work too
 "tight", making them to sound a little poorer...As
 a cat on a leash looses personality... :-)
 
 
 
 Anyway, googleing around, I found an interesting thing about
 the Cheetah M6, that uses the same narrow body CEM 3396
 chips of the Matrix1000. And there is the chance, as the
 site keeper writes, to add some extra waveforms on the
 Cheetah. Maybe also on Matrix 1000?

 Just write me what do You think, I know it's too easy to
 suggest something hard, when You have not to work upon it.
 But, who knows...?

  Great idea,pal. I would like to see
 
  implemented a thing that only Matrix6 seems to have (
 afaik
 
  ) comparing with our little puppy: filter and resonance
 
  discrete for each of its 6 voices.... It makes the sound
 
  fatter, more organic, as I can hear on my
 analog-filtered
 
  Korg DW8000.Chorus?
 
  Francesco.

         This is just a bit of "What
 
  if".
 
   Please treat it as a thought experiment. 
 
   I love my Matrix-1000. I love 8-bit
 
   machinery. And I love modding things, finding simple
 hacks
 
   that make things better without taking large chunks of
 
  your
 
   lifetime.
 
   Good starting point:
 
   I'll have to take apart my Obie anyway; the battery
 will
 
   have to be replaced sometime, and there's the v1.13
 
   bugfix firmware update by Fetz. 
 
   But why stop there? I think there may be
 
   a couple of things you could do to enhance the
 M1000's
 
   scope, following these simple
 
   rule: Tradition: Any modification has
 
   to be downward compatible to existing Matrix
 
   sounds. 
 
   Simplicity: It has to be
 
   simple. 
 
   Aesthetics: It has to fit the
 
   original housing. 
 
   Incrementalism: Even if
 
   it's something big, you'd start small and move
 on
 
   step by step.
 
   Pragmatism: If it already
 
   exists, don't bother building it, buy it.  
 
   The reason for the last rule is
 
   time - there's never enough of it, at least with me.
 So
 
   to keep moving, it is vital to be able to stop at any
 
  point
 
   and still have a working unit. 
 
   So these are the things I could come
 
   up with that might be done.:A per-voice ring modulator.
 
   Switched on by an unused bit in, say, the Unison
 
   parameter. 
 
   Switching the
 
   filter from 4-pole to 2-pole. Making the M1000
 
   respond in real-time. OK, Number 3 seems to
 
   violate my rules of simplicity and incrementalism -
 this
 
  is
 
   a HUGE project, or so it seems. The M1000 is an old
 beast
 
   with a tired heart - the 6809 processor won't be able
 to
 
   respond any faster. But maybe you can use 21st century
 
   technology to assist it - use a modern single-chip
 system,
 
   maybe even something like a Raspberry Pi, and have it
 run
 
   the original firmware, based on the technology behind
 the
 
   MAME game machine emulator. Then go ahead and replace
 the
 
   time-consuming modulation calculation routines by
 native
 
   code. Tweak, repeat. 
 
   The result wouldn't be a
 
   different synth. Anybody who wants to build a totally
 
   different synth may go and buy his or her fucking
 Eurorack
 
   system. But it would be a better synth. An object of
 
   desire. 
 
   So what
 
   would you dream up for the Überheim
 
   Matrix-1000?
