Hi there !

Didn't know about Tim Hecker, pretty nice sounds, thanks for sharing :)

With regards to your rack, I would personally miss at least a few VCA's, a clock source (I don't know the Voltage Block that well but Steppy won't advance without a clock, Pamela's New Workout would provide that and some more, or you could just use of Maths' channels in cycling mode) as well as a mixer since in your plan there seems to be no way to hear all your sound sources at the same time... Also, what was the reasoning behind the buffered mult, what do you plan to use it for ? These are generally only used when you need a very precise copy of a signal, otherwise inline mults could do and save you both space and money. Finally, as a very personal choice, I would not go for a Zeroscope in such a small setup. For me, but that's just me, an oscilloscope is needed when creating very complex signals, I don't think I would get a lot of use out of it for a "small" setup like yours, although that may be due to my lack of experience with such devices.

If you want to start with just a few modules based on the above, I would go for the classic Rings into Clouds + Steppy and Voltage Block for sequencing, some fun to be had experimenting with these very deep and complex modules I think, although I have never owned any of those except Steppy in my setup.

Have you tried VCV Rack ? It's free and while you might not want to make music on a computer in the long run, I found that some time with it helped me understand some modular synthesis concepts before diving into the actual pool. It's a rather good option as it allows to better decide for yourself where you want to go, rather than entirely relying on advice from the interwebz.

Hope this helps !

Cheers,
Diego
