What is the purpose of having more than one? Does that mean like an adsr and a ar? Or would anyone use 2 adsr’s for any reason?
One ADSR for the voltage controlled filter, one ADSR for the voltage controlled amplifier.
Or depending on the implementation, a separate envelope to drive a 2nd filter from an auxiliary OSC (ie. I’ve driving a FreqBox OSC from a little Phatty piping the OSC out through my Voyager)
You can use something like this for compound patches like a trumpet that has a quick sputter at the head end of the gate, followed by a smooth vibrato sine.
I’m looking to pick up a few ASDR modules from synth.com for this very purpose, as to use a MF-101 as a filter thus freeing up the Voyager for more important work.
For this to work properly, you need to send the gate through a mult and optimally use a lag, thereby delaying the firing of an envelope (for maximum flexibility).
At least that’s one example…

You could mix them together to create one complex envelope, send them to different destinations, and have the amplitude envelope differ from the filter envelope.
The DSI Prophet '08 has an extra enveolpe generator, and when combined with the 4 LFOs and dozens of mod routing possibilities, you can have quite a bit of fun with it. Some of my other favorite features about it include separate glide rates per oscillator, and a “delay” knob in front of each ADSR, which allows you to maintain a sharp attack on any of the envelopes, but not have it start until a few seconds into the note. The separate glide rates per oscillator is so cool sounding - this is a feature I wish my new Taurus 3s had. Wouldn’t sound bad on my Phatty either, and would sound especially wicked on the 3-Osc. Voyager.
The separate glides on the Mopho are awesome. I can only imagine how it sounds with the P08 in unison mode!
I think 3 ADSR’s would be better than 2. One for pitch, one for the VCA and one for the filter on a normalized synth. If you want an AR, Turn DECAY to 0 and SUSTAIN to 10. Now the ATTACK and RELEASE only are functioning.
My very basic modular has 3 ENV generators and as I build the 2nd cabinet, there will be at least 2 more specialty EG added. (One VC ADSR and one Universal Event Generator 8 stage envelope)
As you begin to understand sound programming, you will figure out the need for more than one envelope. Try disecting some of the patches factory programmed in your machine or look in the patch book for the OS for examples.
As ive said before, there is no redundancy when it comes to synthesis.
You might have an Env Gen modulate the waveshape of your oscillators or the speed of your lfos. Sequencers can trigger multiple envelope generators which are sent to various places. You can send a delayed trigger signal to an envelope generator as well making unteresting phrases.
Believe me, there are many great uses for having more than one of the same module.

Hey Eric, are 10 LFO’s redundant? (and to answer that; NO. I’m still building more. Can never have enough modulation sources! LOL)
The only time I think its redundant is if you have absolutely no use for it, like having 4 VCLPFs and nothing to run it through or to control it with lolol.
Eric
How does an EG modulate a waveshape? Does that mean the wave changes with the envelope?
Yes, you can send the control voltage from the envelope to the wave form and have it change the shape of the wave to the slopes of the envelope. You can also route it to change the pitch of the OSC. With pot mapping, you can send it to almost any knob on the Voyager. A lot of really cool sneaky things can be done with those menus on the Voyager.
