Thanks for the positive feedback. Really glad to hear I'm going in the right direction, especially from such an experienced synthesist like you Lugia. The quad VCA will be on the "first to buy" list :)
Morphagene seems like a great choice too. I'll give myself some more time to think about that. But I gotta agree, Rainmaker seems to be an amazing delay module with endless possibilities. Definitely going for this one.
As for sequencing. Outboard gear is an option, thanks for the suggestions. At first glance, I like the Squarp Pyramid. But since I will be moving the system from my apartment to my studio quite a bit (which is another reason why I went for the Intellijel Case), I think the best option, in the long run, will be a sequencer in the system itself. Just not sure which one to get. Voltage Block + Varigate looks also nice. So many options.....
One more question: is the Sisters Filter enough to start, or should I put the Optomix on the "first to buy" also?
