Dream on. You could show controller automation lanes as digital audio workstations do, but those are only as informative as they are consistent with some scheme like General MIDI and a standard sound architecture. Once you start resampling or using modular routings any kind of timbral notation schema goes out the window.

I've seen attempts at this, and if you email I'll try and dig you out a reference but the particular book I'm thinking of is in a box in my attic right now. However I can't say I've found them very informative. When I think about timbre I think about the whole synth architecture and program it in my head, for many timbral ideas it's just a matter of walking up to the synth later and dialing it in.

Most electronic musicians stick with simple diatonic scales or within modes, at most switching in and out of relative minor. Harmonic complexity and timbral complexity don't go very well together.
