A bigger case.
As @JimHowell1970 says 'either start with a bigger case or massively scale back what you are trying to do’.
And as you can see, all the people here will advise you to do the former. We say this with the full knowledge of the facts... and to really save you any frustration afterwards.
Utilities and modulation sources.
Once again, we have to underline this other advice from @JimHowell1970 who, with great laudable persistence, tries to remind the necessity of these modules throughout the pages of this forum; and you know what : he is right!
Can you imagine a film with just a few stars and no supporting cast, no extras, not even a little furniture in the set? This is the unconscious bet and the mistake we all make a little too systematically when we approach the modular synthesizer and in front of all its big stars (Clouds, Rings, Morphagene, Basimilus, Bloom, etc.)
Nothing really important to add to what others have said here.
Modular is a bit like cinema. ModularGrid is not the USC School of Cinematic Arts, or the Ecole Nationale Louis-Lumière. But you've come to the right place. The amateurs and even the less amateurs have almost all passed through the benches of ModularGrid :))
