Quote Martin Walker:
Ironically most musicians starting out with modular synths in the early days did so on a ‘suck it and see’ basis, and discovered many useful things by accident
When a synth voice had essentially 4 controls, you could work that way. Though I wish someone had told me the concept of balancing other settings so that 99% of a given knob's travel wasn't "dead space" (have I explained that clearly?) a little sooner. Much the same idea as gain staging through a mixer channel. I suppose you MIGHT work it out for yourself, but a little tuition avoids a lot of dead ends.
Once FM synthesis arrived, I think the chance of doing anything useful by pure intuition effectively vanished! Let alone the incredibly powerful but almost impenetrable VAST synthesis engine on my Kurzweil keyboards. Getting anything out of that without "standing on the shoulders of giants" would be highly unlikely!
