[sdiy] presets on a modular

[Morbius]

[note:]

Being new to the list, I'm not sure why I didn't get a
copy of the reply I posted with the subject line:
"presets & patching > combining 2 replies"... but,
evidently others did get the posting... 'cause they
replied to it.

Can anyone explain to me why I didn't get a copy of my
posting mailed back to me thru the list?

Anyway- I want to insert a repeat of part of what I
said there at the bottom of this posting... seems
relevant... I'm just not sure everyone got it.

[my repeat from previous posting:]

(oh, add to this: I have normalized my osc.s (8 out of
9), and my EG's (4 out of 6).

So far, for a preset system for my modular dotcom, I
use a simple 5x5 matrix switcher (simple 1/4" jacks &
toggle switches) as a router. I also have/use two
Q-143 "Presets" modules combined with several Q-128
"Switches". It makes a pretty effective 'on-the-fly'
patching/routing system that I like a whole lot. The
Q-143 "Presets" module not only has two A/OFF/B preset
variable (+/-) voltage sources, but also two A/B
switches that are all tied together in that module.
This combo of the Q-143 & Q-128 can be quite
effective.

In live performance using a modular, I like to be able
to (as a very basic function) be able to switch
between waveforms. Here is one preset I use often:

The first switch setting (A) gives me 2 sawtooths
(slightly detuned), a sawtooth tuned to a fifth, and a
sine one octave below. LP filter settings (with EG)
set for very percussive response. This patch gives a
real 'ballsey Moog' sound.

Changing the "presets" module switch to the center
(off) position shuts off all of the above, and give me
2 sine waves, one of which is tuned 2 octaves below
the other; no filter; and a variable delayed vibrato.

Changing the "presets" to the (B) setting shuts off
the above, and gives me 2 square waves, slightly
detuned, with two different portamento rates, and a LP
filter setting that is 100% open, with about 30-40%
regeneration.

Ok... three, very basic sounds... but osc.s, filters,
and various other parameters are being switched. And
that is all done with one Q143 and two Q128's.

Add to that, the routing of the matrix switcher, I end
up with a very handy preset modular for use in live
gigs. At the flip of a switch, I can easily do things
like:
apply S/H to osc.s
apply S/H to filters
apply Q-119 sequencer(s) to osc.s and/or filters)
apply external MIDI sequencer(s) to osc.s and/or
filters)
apply LFO modulation to osc.s/filters
apply EG (+/-) voltage to osc.s/filters.

Now... that's a good deal of stuff you can do without
changing one single patchcord during a performance.

On the downside:
It takes a while to set up, and you have to know what
you're doing... and memorize it; ummm... there is no
memory, other than what you have in however many
braincells you have left.

Thanx for the patients for me repeating myself...
redundantly.  ; )
