Does anyone have experience with writing scores with complex synthesizer parts? Let's say a Minimoog or Prophet-5. How do you get the performer to achieve exactly the sound you desire using paper only? Would you have to add extra lines detailing the positions of each and every knob, or some abstractions (filter, resonance, waveform shape, use of oscillator sync..)
I know you can always spend personal time with the performer to get your ideas across (which is desirable even when scoring for classical instruments) but the point of a well-thought out score annotations should be to minimise that time, I believe.
Any ideas greatly appreciated.
