Thank you Kale. I found that the echo & reverb, plus being a little low in the mix made it sound even more 'other worldly'. I believe that a real theremin generates a sine wave, so it should be pretty close.
Lovely, that's a great combination. Short and sweet is always good. Surely only a matter of time before I get an E-ther, although I know it's not going to be as easy as you make it look
I'm just doing my best and having fun. (spoiler:) Being able to make multiple takes and choose the best is very helpful. I've also developed some tricks, such as using the keys on my keyboard there as a visual aid for positioning my right hand. In the past I have actually drawn myself a scale on paper or in sharpie on the table, but I can't do that on camera, that would spoil the magic a bit! A bit of reverb and echo helps too!
