mutator patch
Hi list,
I found this at the clavia homepage:
http://www.clavia.se/products/nordmodular/software.htm
a patch which mutates the sound in an interesting way.
I am shure it is also possible in max/msp, and it would be
a cool improvement (in fact I was considering looking for a G2 machine, after
reading about this mutator thing, but hey, max/msp should be able to do this too!!)
Just wanted to give an idea for a new cool patch, if somebody is bored ;O)
would be a big thing for the new share site!
cheers

The Galaxy voice editor/librarian had something similar on its "Factory"
menu. "Shade two" interpolated all of the parameters of one voice to the
corresponding parameter of another. I forget the name of the other process
but it also took two voices of your choice and created a bank of new voices
using the "guide" voices as the limits of random choice for each of the
parameters. When I was using a bank of Proteii and a TX816 as my touring
orchestra, I wrote max patches that did this in real time. You can hear the
TX816 in "Five Summer Scenes" and thereal time mutation in "Colony." Both
are on my web site.

Hi Roman,
Shure I would like to help you!
Could you pls send me (or to the list, so all could
participate and help) your "mutator"-patch?

It doesn't offer the nice pictures like the clavia editor, but you
should be looking at pattrstorage for your 2-point interpolation
needs. With some work, one could use pattrstorage to perform
specifiable randomization of named parameters in a patch, too.
All that said, the G2 is a _great_ instrument and you should get one
anyway!

Is the g2 also good for noisy, droning experimental sounds?
Is it really useful for physical modelling?
I had a nord modular (1.version) but gave it away, because it sounded too cold for me (but I had great fun making patches).

Mutation is the easy part. What was always difficult was finding the
information about data format and sysex codes in the synth. Only a few
synths include enough documentation about midi implementation. The Proteus
manual was particularly good and the Yamaha X series became well-known
because of its wide-spread use and a lot of hacking.
Here are some issues that I recall in writing your own mutator in max....
Interpolation is not linear for many voice parameters, for example these in
the Proteus,,,
sample number - samples are not stored in an order that makes perceptual
sense even if we knew everything about adjacency in timbral space. I created
my own map based on subjective judgments and instrument classifications.
LFO wave shapes - is a square wave half way between a sine and a
triangle?
Parameters that link controllers to synth parameters
And this in the X series...
algorithm number.
Using Galaxy's random patch mutator produced a lot of voices that didn't
make any sound. It was a great way to "shop" for unusual voices but I did
not think of it as mutation in the usual sense - i.e. Small developmental
steps.
If your synth has on-board editing things can be easier. You can use max'
sysexin to watch what happens when you press the buttons on the synth. In
particular you want to know the codes for requesting data dumps from the
synth. Having that you can capture data, modify it in max and then send it
back.
Once again I suggest my piece, "Colony" as an example of doing this in real
time. Voices are loaded from the synth, bred and then sent back.

Some responses to Raman....
Midi controllers - I was referring to the connection of midi controllers to
parameters of a voice patch. It would make little sense if controllers A &
C were being used for some purpose and a mutation reassigns to controller B
that may not even exist.
Requesting voice parameters - the Proteus, as I said, is very permissive
about this. You can send messages to change individual parameters with
short sysex messages interleaved with other other time-sensitive data. This
also works on some Yamaha synths.
Work - some things require work. Just because a synth manufacturer didn't
think a parameter should have midi control doesn't mean a composer should
accept it.
Single device - I found writing custom control patches well worth the effort
when I had spend >$10K on hardware synths. The idea of custom control is
the very reason we have MSP.
Colony - you can hear it along with other works at

Many hardware designers were/are out of touch with "experimental" composers.
Moving away from hardware synths to software like MSP, SuperCollider,
csound, RTCmix and the like solve some of the problems of going down the
road less traveled. I still write music for traditional instruments and I
accept and revel in their limitations but once over the threshold into
digital media I no longer want to do things the way they have always been
done. I no longer have to.

I DO invent new parameters and relationships between parameters crossing the
line between image and sound with ease BECAUSE the designers of
MAX/MSP/Jitter DO understand that the invention of tools is part of the
artistic process.

I don't know where you live but I have reasons beyond being a composer to
choose a new president...but I'll express those views on another list -
perhaps dumpthatchump.org
