It seems to me that a Theremin has an interface that couldn't get
much more intuitive as an interface.
Using it to control the pitch and amplitude of sine waves wouldn't
involve involve switches, buttons, gates, Sample-and-hold, threshold
triggering, or pulse waveforms. It's not so much my feeling the term
mapping was misused, but I also saw so many suggested solutions
dealing with pitch tracking, MIDI and digitizing controllers which
all surely add layers of quantitization inaccuracy to a process that
doesn't need any of it.
Had there been a different goal and or different interface then one
might have a reason employ mapping and/or digital processes.
I should have used "inherent lack of maps" not "complete lack of
maps" in my post. I guess I didn't want to use inherent twice in the
same sentence ;-)
Though I don't see why you mention compressor/limiters, they aren't
necessarily or even ideally digital. Wouldn't the process be better
described as a transfer function? (fwiw A friend is about to spend 5
figures on a Fairchild)

For what it's worth the Doepfer the process doesn't involve "mapping"
- there is no map, that's a term better applied to MIDI data for
instance, simply put Doepfer makes some Theremin-like antenna modules
that output control voltages as you've mentioned. You can use that
voltage to control or be scaled to control anything that accepts
voltage control. Doepfer makes VCOs with sine waves. I just paused
on the word "mapping" because I believe one of the main attractions
of un-digitally assisted analog technology is a complete lack of maps
and the inherently stepped/quantitized data involved (nothing wrong
if you need it but neither sine waves nor theremins are stepped to
begin with)
