Hi there.
New here. Just stumbled on an ambient eurorack YT video. I really like ambient as a whole and what this user has produced.. which really pushed me researching so..
Since a few month, i have been reading and watching videos about modular synthesis- principles , concept etc and have read/watched videos about most of the presented modules to understand their respective functionality. But i am a bit at loss when see this rack and i read ‘you never have to many vca’ which is quite essential to allow ambient modulation..

NOw i do not mean to copy/paste this rack but i would like it to serve as a foundation for me to learn- i do not intend to buy everything that would be madness considering the need to understand and appreciate each module..

So i have a couple of questions!

1:Does this rack miss vca? Or the like of O_C , PNW & marbles are sufficient source of modulation?
2: what is the mult module used for in there?
3: any issues you see with it?

Advice much appreciated
