Not entirely, which is why techniques -- which can be realized using
a hardware modular -- such as FM, additive, etc. are valid and useful.

Afaik, Modcan offers a a flanger with voltage control.

I do not know if he was trying to "imitate" sounds.  However, it does
not seem as though he was trying to accurately recreate a specific
sound, such as a specific bird call or the sound of a particular
species of insect.  For all we know, he arrived upon them by happy
accident.  While one can easily create a brass or string patch on
almost any synth which might remind the listener of the instruments
that can create those sounds, it is easily distinguishable from the
real instrument.
