Yes - I am patiently waiting for this to arrive. Hopefully by next week. If configured properly it should give me 5 voices of poly/paraphony. I'm hoping I can figure all of this out!

Yeah, that's pretty cool. It'll give you the CVs and gates. But I'm talking about EGs for those gates to trigger. I'll have to go hunting for it...

Ahhhhh. This is interesting, thanks for finding it.

Forgive the question, but this is all rather new for me - for now, I could route everything into one EG which would be considered paraphonic, correct?

I suppose, technically, but you'd have no gate, even, between the notes. I would think, at minimum, you'd want to gate the output of each oscillator indepependently, otherwise you have a full chord at all times. Which may not be a bad thing.

Patch an organ into a voltage controlled filter.

Patch an organ... Funny!

As for gating the outputs independently, I assumed the Grove Audio is supposed to do that. At least that's what they're all telling me.

Why's that funny? Oakley/Krisp-1 EFG should be utilized...

The Grove will provide gates for each note. But those gates need to gate something. I'd guess, at a minimum, you could run a gate to the CV input of a VCA on each "voice," and just have an on/off switch. I see you mentioned the octal linear VCA. it takes 0-5V CV, and your Grove's gate outs are 5V, so it seems like you'd be able to switch voices on off like that. I'm kind of surprised I've never actually tried it! It would pretty much sound like... an organ plugged into a VCF. Thorsday's not very far off the mark. It worked for the Who. ;)
I think, like so many things modular, you need to get it all in your grubby little hands, and hopefully what's possible will become clear, and you'll have a better understanding of what's not (yet) possible for you, and what you'd need to get to make it work.

This link is for a draft copy of the GMS-744MU Operation Manual. There is a section containing some example paraphonic and polyphonic patches that should show where gating EGs and VCAs need to go. The examples use a GMS-710MU VC Envelope/VC Amplifier module which is a combination module. This draft is based on the GMS-742a Midi/CV converter so some sections may not apply to the newer module.
