| br>Nicely laid out workflow (albeit but one way of doing things). Depends on your friend's budget and current understanding of synthesis in general, and modular in particular, but I started with a fraction of that - VCO => VCF => VCA + Maths. I built up pretty quickly once I began to understand what was going on, but I reckon starting with a fully-featured modular from day one might be overwhelming for some.
But you'll be a better judge than I whether your friend can afford/comprehend the whole lot in one go. br> br>
