MOTM

What I meant was, I'm finally getting into the game and ordering modules
instead of sitting on the sidelines drooling. Over the coming weeks, I
expect to be doing some soldering instead of posting way too many messages a
day and playing with bitmaps!

Besides, there's been so much discussion about the mixer that I'm confused
as to how Paul will actually finalize it.

Of course, you know I was just pokin' fun Dave. Congrats on ordering
modules. They are all super. Still drooling over the VCOs.

Well, I sure am glad we had such a good open discussion on the subject.
I'm sure it will be great. I know I heard a lot of discussion too for an
output mixer. But, for now (and maybe always) my little Mackie does a
great job at "audio" mixing at the very end of the trail. I know, I know,
it is not voltage controlled.

Did anyone besides me see the motorizerd 10K pots in the All electronics
catalog? Seems like it was a low voltage DC like 6 VDC for control or you
could turn it with your hands. That might be fin for some DIY projects.

Now, I have a question about EGs. Someone on synth-diy for whom I have a
great deal of respect recently introduced a voltage controlled ADSR. Why
would I want my EGs to be voltage controlled. I though the purpose of EGs
was to produce voltages for the control of other modules liek VCAs and VCFs
and such. If I have a voltage controlled ADSR, how would I use that?

One use is to have the keyboard pitch voltage attenuated and applied directly
or inversely to the attack of an EG. Thus higher notes on the keyboard have
shorter or longer attacks than the lower registers.

Also, with a sequencer, you can set the attack of each stage. Or individual
release times. This is nice when you're using one row of the sequencer to
set individual note times.

Imagine using a clock to trigger both the ADSR and the MOTM-100, and using
the out on the sample hold to set the attack time. Hey, imagine four
MOTM-100's controlling attack, decay, sustain, release. No wait, eight
MOTM-100's controlling two ADSR's, one for VCA, and another for the filter...

...I'll NEVER have enough modules :-(
