[sdiy] suggestions for extra modules in DIY EMS VCS3

[Harry Bissell]

I'd put a version of my "morphlag" in it. Its great as a keyboard
lag processor. Find the schematic at wiseguysynth.com

So now I'm going to redesign everything in order to use 2 20x20 matrixes in the synth. This also gives me the opportunity to add a lot of extra modules.

I had an AKS for a long time. One mod Robin did for me that I used all 
the time is an inverter. Because of the stereo nature of the instrument, 
an inverter is extremely handy for creating panning modulations etc. I 
would highly recommend adding one, unless one of your existing modules 
has one incorporated.

I often wished I had an extra trapezoid, so it's good you'll have two. 
Multiple filters will be great to have too.

Do any of those oscillators have sync? That's a mod that's very nice to 
have also.

Also, what about VC reverb? The Synthi reverb has its own character, 
breaks up wonderfully, and I think is a vital part of the Synthi sound. 
I can't imagine a Synthi without one.
