[sdiy] Theremin tone/waveform' question

[Paul Perry]

I can't imagine what audio frequency modulation of the waveform of another
audio signal would sound like - though many modular owning listmembers
(especially those with serge knockoffs) probably do.

But in my quest for theremin 'tone', I was meaning, a much lower rate of
modulation of the waveform, in line with the shift of frequency of the
output.
So at the lowest audio frequency there is a saw waveform, and this shifts
progressively to a triangle at the highest frequency.
And the output is rounded.
