Subject: more stuff!

Hi gang!

1) Hey Larry, I broke the first switch on the first MOTM kit I got (wasn't
even tightening it, just trying to get it vertically aligned). Thanks Paul
(and Chris?) for the part number. But Larry, I think you've been doing too
many push ups (or you need to find another outlet for your aggressions).

2) I wanted to mention to Chris that I like using exp envelopes (which has an
attack curve in reverse orientation to a "real exponenetial curve" as I'm lead
to believe; all exp ADSRs to my knowledge share this) with exp input on the
VCA often; it's worth checking out.

3) Un-implemented MOTM 110 mod -- DC coupling switch. Drill hole in panel
below CV MOD knob. Install spst switch (do not overtighten). Connect switch
across bypass cap (using 3 cond. sheiled cable???). This will allow gating of
CV, as well as audio; wish I'd thought of it before assembly.

4) About filter Q

The (damn) Serge filters have something similar, not a control but a separate
input for a pulse called RING. Works great! I love it! Paul should add it!

Dave, if you want me to say more, you'll have to say "pretty pretty please;"
in the mean time, look at that Serge page filter section.

5) And finally,

And a number of people are clamoring for that (BTW, zero is a number)!

Paul is very helpful in that way!

Larry! I think I remember you posting this ("no ADSRs?") when you first got
it, and I said something like you have to have a minimum of 3 per voice. I've
changed my perspective recently, that's far too few!

In 1983 dollars:

>> 4710 Ring Mod/VCA (not a dual module, use the RM AS the VCA!)
$22.50
>> 4711 Stereo Mixer
$29.88
>> 4712 Reverb
$26.95
>> 4740 ADSR
$25.95
>> 4720 VCO
$34.95
>> 4730 VCF (multimode)
$37.95
>> 4750 Control OSC/Noise
$21.95
>> 4771 PSU
$29.95
>> 8771 QUASH (uP S/H) (?)
$34.95
>> 2720 Env Follower
$19.95

I bought a 4017 in 83 in order to replace the broken RM in my ARP. I never got
it working in any satisfactory manner, and that experience put me off building
EM circuits for a long time; the biggest (EM) mistake I ever made.

At the same time I bought some of the (CEM based) EKx series. So this might
really hurt (again, 1983 dollars).
CEM 3310 $6.95
CEM 3320 $7.95 (hey! that's not much cheaper than they are now! And they
actually sound quite nice IMO)
CEM 3330 $6.95
CEM 3340 $8.95

At the risk of stating the obvious, a VCO, VCF, VCA, ADSR does not a synth
make. You NEED to have those (and they need to be good) but it is the more
esoteric modules that make a synth have its own personality. However, if ten
companies put out the VCO, VCF, VCA, ADSR core, and nothing more, all the
companies can bite the dust, before any of them have a chance (or a clue!) of
putting out the more exotic modules; and we're all left with a bunch of VCO,
VCF, VCA, ADSR collections. Sorry if my original point was not clear.
