I've owned a small AE modular system for a few years and recently got hold of the DIY breadboard
(BRAED BOARD) module
The AE modular system sounds fabulous.
I purchased the system years ago to tinker with electronic circuits.
It uses +5v so you won't electrocute yourself.
The BRAED BOARD is a perfect addition for the experimenter in all of us.
Check out the AE modular wiki for more ideas
I am always running out of VCAs (they say you can never have enough).
So why not make a Buchla style LPG as my first project.
AE modular do also make a LPG module if DIY isn't your thing.
I think this module (called the LOPAG) is powered, and has the added option of switching to VCA mode.
This DIY version is passive & super super simple.
Parts
+ Vactrol
+ LED
+ 10K resistor (x2)
Yes ! that's it.
Actually, you don't even need the LED. Its only a display.
You can of course get more complex, but those basic parts are all you need.
So experiment.
PS: if you can't find a vactrol, just roll your own.
You will need a LDR (light dependent resistor) , a LED & heat shrink.
More info about vactrols and how to roll your own here:
A short note: The LPG has low pass filtering characteristics as its name implies,
so if you want a clean unadulterated sound, use a VCA.
Some pics of my soldered version of this circuit using a NSL vactrol & a DIY vactrol.
