Thanks for your suggestions.
My case is an Intellijel 7U 104; I've checked power supply and according to modulargrid info it seems ok.
Kink is in my list and an additional ADSR module was there too... I have to rethink about it.
Good catch on ES-9.
As for clock divisions and additional LFO, I'm relying on Eloquencer and Pamela's New Workowt that are providing both. Is there an added value to have LFO and clock divider separated from the 2 modules ?
I have some doubts about Stages and Marbles; maybe Eloquencer an Pam's are already providing enough uncertainity/randomness and envelope/lfo services so that Stages and Marbles become sort of a duplicates.

Speaking of complex sources to possibly substitute 2hp VCo& MMF & Stages & Marbles, what are you suggesting ?
Maybe something completely different from what I already have such as make Noise Morphagene ? Something else ?

THanks for your help
