Thanks.
What has steered me toward even considering modular in the first place is that while I love the sound of various hardware synths, they all seem to paint you into a corner. I liked my Minibrute for what it was but grew to want a different filter and snappier envelopes, which made me think I would be happier with a Moog Little Phatty or Sub Phatty. After demo'ing a Sub Phatty I realized it scratched an itch, but it would limit me in it's own way too in short time.
I'm always drenching synth sounds in delay and reverb or looking for other means to try and create layered ambient sounds, so when I heard some of the stuff people were doing with Mutable Instruments modules that can't be done at all on existing fixed architecture synths - then it felt right.
I might scale back my ambitions, get the Mother 32, an extra VCO, and the Rings - then think harder about what's actually missing. I'll likely need time for my wallet to catch up anyway.
