FXpansion have released Enigmatron proof of concept/preview VSTi for Windows, check it out in this thread for more info!
"The ENIGMATRON is a solo/lead synth based on the concept of our MYSTERON "theremin emulator". ENIGMATRON uses the principle of continuous synthesis to generate smooth, gliding lead/solo sounds and ambiences.
ENIGMATRON extends the MYSTERON concept in two significant ways:- onboard effects / signal processors, and onboard modulation
generators / LFOs. It will, in future, also provide the capability for external modulation sources (pitch bend, MIDI CCs) to be mapped as modulators."
