Hello.
Does anybody have information about the waveform produced by the Theremin? I
tried to google, but some places say it's a sinewave, and some others that
it's not exactly it (and it in fact sounds richer). However, I cannot find
any real analysis of the timbre of this instrument (weird...). Aren't there
any csound orchestras for that?

Cheers,

Pedro

Hi there

I managed to make a pretty realistic theremin using cSound, you can hear on:

www.myspace.com/josephsanger

I eventually found, after a lot of googling, that it's basically a half 
sine wave, so it's as if the bottom part of the sine (below zero) is 
reflected back upwards again. It would be SO much easier to explain with 
a picture...

Here's the ftable I used:

f1 0 65536 19 .5 1 0 0

Hope this helps

Joe
