you can do this with an encore expressionist (it has polygroups). your
MOTM
has to have at least one vco, vcf, env and vca *per voice* . Set these
up as
individual mono synth type patches to your expressionist and assign
each one
to a channel. assign your channels to a polygroup and your all set -
just be sure to dial your voices up the same way - like setting up an
oberheim 2/4 voice.

Has anyone got a diagram or drawing of their plan for a 3 or 4 voice (or
More) MOTM? If not, it might be a good referrence if one of you graphics
type guys could lay one out with existing modules and say a Kenton Pro-4 or
Encore Expressionist. Just a thought and kinda of watery request HA!

Polyphonic playing on a big modular can be a very special
experience. At first one might think that many identical modules
are needed, like four M-440 filters for a 4-voice modular,
or 8 ENV generators ...
But in practice, you can get good (and often more interesting)
results with a mixed bag of modules. Using 4-pole filter for
one voice and 2-pole filter for the next, or using a VCLAG to
fill in for missing ADSR modules, is not just a surrogate
for N equal voices, but it can give polyphonic playing a new
quality.
For a start, it's good to *attempt* to set up a similar sound
for each voice. This will not be possible with different filters,
but you can set them as close as possible (like, using a slightly
lower cutoff point on the 2-pole VCF to make up for the less
steep slope). Of course playing with N totally different voices
has is benefits as well, but playing with *slightly* different
voices has a charm of its own. I don't know why, but starting with
different filters and trying to get close is more satisfactory
than using identical filters and setting slightly different
parameters. (;->)

Of course this is the beauty of the Oberhiem 4 voice IMHO too.
All the best

Polyphonic MOTM

2004-05-13 by Mike Marsh

Hi All -

Just uploaded a snippet of a peice done by programming my PSIM to
generate notes algorithmically, then put them out via a shift
register. The result is pretty nice!

4 vcos: two 300s and two 310s. Each through one channel of low pass
gate modulated by an 800, then out to various processing. One out
goes to the FS, one to the beautiful 410 (REALLY REALLY gorgeous when
processing the out from a LPG), and the other two into Tony's SVF.

Pretty! Nice!

Mike

Note that if you listen to the file in MONO, you'll get phase-related
dropouts. This happens with a stereo file created using the FS.

Yes, Cyndustries but behind a Schaeffer panel. I really really like
the sound of vactrols! Hint hint Paul: anothe vactrol based filter
would be awesome.

How about that algorithmic melody? Pretty cool, huh? This was old
hat in the bygone MIDI days. In these more modern analog modular
days, algorithmic is pretty hard to come by. But now I can program
to my heart's content and have it play back on a real instrument :)

Life is good.

Mike

What exactly did you do then to create that melody?
Curious...

Re: Polyphonic MOTM

Hi Robert -

I created a BASIC program that generated the melody and downloaded
it to the PSIM module. Here's how I explained it in the PSIM group:

"The code, ahem, borrows from the Good Dr. Mabuse (the shift register
stuff), Brice (lots of stuff) and of course Master Grant (lots of
other stuff). I added the note generation code and an array with
one octave of the C Major scale.

The MP3 was done using the 4 SR outs of the PSIM into 4 MOTM VCOs
(two 300s and 2 310s). Each goes into one channel of a Quad Low
Pass Gate each channel of which is modulated by an MOTM 800 EG,
which is triggered by the gate produces on the AUX of the PSIM. The
OUT of one LPG goes to a frequency shifter, one goes to the favorite
and very nice MOTM-410 filter, and two go into an Oakley SVF. A
total of 8 channels are mixed on my Tascam FW-1880 then into Cool
Edit Pro.

It's nice that the PSIM has 4 outs and the LPG has 4 ins!

Anybody could modify the code generation code and get their own
melodies. You could also change the scale used (there is a minor-
like scale included in the code, for e.g.). Lot's of possibilities
here"

If you are even more interested, I posted the code to the
SynthModules group (also here on Yahoo).

Mike
