how "modular" is the GM if I want to ...

... later on add a DFAM, extend the GM case and add a 49 note MOOG keyboard, or 61 note MOOG keyboard?

thinking the DFAM and GM would be ideal together like that, and with a 61 note keyboard I would never want for anything ever again, I'd delete Reverb/Craigslist, live an honest and humble life from then on

that is a novel idea: transplant the GM into a larger case & add more modiular

not sure how everything is connected inside; it may be possible to just swap the keyboard?

there is a youtube vid somewhere where they rip one apart

I've been thinking about getting a 2nd Grandmother. Then getting a 61 note keyboard from Moog .. which hopefully would have Aftertouch I could patch into the filter and/or LFO.

Then I'd have 4 sweet oscillators, one keyboard, all the patchable goodness I'd ever need for the rest of my life

what about just buying a Matriarch?
