Perhaps i should have started my whole PatchPierre blog with writing about the most basic and essential A-100 modules first.

| How the four parameters A, D, S and R change the shape of an ADSR envelope |
It is a simple ADSR (Attack, Decay, Sustain, Release) generator.
When this module is triggered it generates a variable voltage, changing in time, called an envelope.
The shape of the envelope is set by four variable parameters: Attack, Decay, Sustain and Release.The envelope is started (triggered) by a gate signal either from the internal gate voltage on the system bus or, if a signal is put into it, from the gate input socket.
The varying voltage (visualized by an LED) is output in normal (positive) and inverted form, and can be used for all kinds of voltage controlled modulation of any VCO, VCF, VCA or other CV controlled inputs.
The envelope can also be re-triggered, but that only works when the gate is opened.
The module has a three-position toggle switch between three time ranges.
The envelope time can be set from about 50 microseconds up to several minutes.
Okay... There's not much extra to write about this elementary module, although i do like the inverted output (plus that it has two 'normal' outputs).
I should say that there are more economicly priced other envelope generators available.
My advice is to get yourself one of the Quad envelope generators for example... if your modular gets bigger you will probably need more EG's anyway.
I do have the four-fold A-143-2 Quad ADSR, but the A-143-1 Quad AD with only Attack and Decay, or perhaps the A-142-4 Quad Decay with just decay are just a few of the other options if you are looking for expanding your modular with basic EG's...

I love the quad ADSR module myself, and regularly use it as a flexible LFO since you can retrigger it by using the output of the ADSR stages. If you use the Decay-phase output you get a LFO with a lot of control of the slopes.

The quad ADSR is awesome and almost makes me regret buying this module. A post on that will follow early next year when i have a bit more time. I might include your tip! thanks
