Subject: RE: VC EGs

From: JWBarlow@...
Date: 2000-02-03

A guy can't go to work for one day without having the MOTM list go wild with
visions of VC EGs. Unfortunately, under the influence of the evil Moe, many
great opportunities are missed all for the sake of his self serving schemes
to control the world through the use (misuse) of MOTM equipment. Ah, if only
he'd use his talents for good, and not evil!

Now for the side of right and truth!

1) A 2U dual (or even a 3U triple) would be preferred over a 1U single --
though I could live with 1U.

2) While the evil Bradley would like to see a gate LED, I find that an LED
which follows the output voltage of EGs is much more enjoyable to watch -- it
has a soothing effect (Moe likes the blinky ones since they cause a more
agitated state in the general populace).

3) If there is an end pulse (a pulse which goes high at the end of the cycle)
to be used for retriggering the EG, one would need a mixer if one were to use
the EG as a triggerable LFO since there is only one input -- I do like the
idea of the end pulse though, for those of you new to the list. If one had a
"CYCLE" switch (somewhere) one could still use the gate input -- but the END
output should still stay!

4) The Delay is also a good idea, and there seems to be a lot of interest.
Yet another reason why we shouldn't be limited to the 1U (single EG) format.

5) I have to differ with Dave V.'s point about having a sustain length
control. I think controlling the time domain of the sustain parameter would
be more easily be done by controlling the length of the incoming gate signal.
I should also mention that I tend to prefer varying gate lengths over static
ones anyway since it sounds more natural to me -- there is an interesting
take on this in the Digisound schematics though which uses a CEM 3310 to make
the sustain have a decaying contour similar to a piano I think.

6) I am interested in Hugo's idea of a peak length control since I've done
the tiniest amount of experimenting with this and found it to be a very
powerful tool as he suggested! I'm not sure this warrants a pot, however,
possibly a three position switch -- anybody have any useful ideas about this?


Finally, I haven't finished with the Crow, Roy, Hugo, et al. super whiz bang
gotta read a twenty page manual to get it to do anything costs about $800
scroll through a hundred menus VC EG, I'll get back to it soon. But I'm glad
everyone sees the usefulness of the AD/AR EG -- and I really like the VC part
(thanks, as always, to Ken for pointing us in this direction)!

Gotta quit my day job so I don't miss this useful MOTM development time!
