I have Sonicouture's Ondes Martenot, and it is capable of making a pretty convincing Theremin sound. It's not a Theremin, but it can sound quite close.  In fact on the "8 Best Free Theremin VST" page at the end of the first paragraph where it mentions artists that have used it and they name Radiohead, that is a mistake.  Jonny Greenwood of Radiohead plays the Ondes Martenot, not a Theremin (although knowing him, he probably has played one at some point).

At least he plays the OM in the studio and a few special shows.  It's a unique, old, and rather fragile instrument.  So he asked Analogue Systems to develop an Ondes style controller to use with his AS Modular system and they produced the French Connection controller for him, which is what he uses on stage these days.

If you want to see 4 of them in action, check out this video of Thom and Jonny (joined by Thomas Bloch, as mentioned on the Sonicouture site, and 2 other people) performing How to Disappear Completely

(poor video, but the audio quality is good)
 
So check it out. The Sonicouture  OM is sweet sounding and can do a lot more than just a Theremin sound.  If you haven't tried any of SC's stuff before, you're in for a pleasant surprise.  They make fantastic sounding instruments.
 

If you have one of the Roland synths... 1080,2080,5080 etc... maybe some of their other synths too not sure.  There is one of their original patches that does a great job faking it called "Helium Queen".

There's one in Rapture / Rapture LE (if you don't have the full version) called Theremin vox in the leads section.

Its a happy little ditty! Theremin sounds kewl.
 
 

Thanks, Mark.  I don't know why you thought I wouldn't like your music.  I like a lot of different styles and your track sounds great.  That drum part in the intro would give Dragon Force a good run for it's money: that is some fast playing!
 
Keep up the good work and thanks for the Theremin tip.
 
(When finished, the track I'm working on should be the musical equivalent of a room with a lava lamp, macrame plant hangers, and a girl in hip-hugger jeans and a tie-died shirt.  )

You're describing my Grandma. There are Theremin patches in the IK SampleMoog.

Haha, Bass Daddy!  That's good.  Most of my songs are inspired by real people and this one is based on a 20-something female I know who is a modern version of a hippie.
 
Anyway, guys, I got Spooky Keys working.  If you want to do any flying saucer or ghost music, get the free download for Spooky Keys or Super Spooky Keys.

Also, Moog just released its cheapest Theremin yet:

Here's a review in SOS: http://www.soundonsound.com/sos/may15/articles/moog-theremini.htm
 
SOS mentions this at even half the price, about $150 http://www.lostvolts.com/
