So here goes with initial reactions.
I was not disappointed on opening the box. It was lighter than I expected, so no worries about putting it on my mike stand, and the finish is really good. It has a reproduction period piece feel to it, and really deserves a matching wooden stand rather than a modern black tubing mike stand.
Plugged in a battery and hooked it up to my Marshall MS-2 micro-amp (it's tiny) switched it on, twiddled knobs and it made noises. Went to Kees' notes on the laptop, followed his instructions for tuning it, and it worked as advertised. Hurrah!
By golly this is fun. I experimented with emulating a police siren - fairly easy - found an appropriate distance to move my hand after a minute or so, but really hard to maintain it accurately for anything more than a couple of woos.
Wolf whistle... fiendishly difficult to get both hands to do the right things. Occasionally I found a bit of it. I'm going to have to work on that.
Clangers (a classic British children's animated sci-fi - the Clanger's voices were slide whistles, played to a written script) pretty easy to get a clangeresque sound, harder to make it talk, but could be a good exercise for the volume hand, and if I can make it talk I'm one step closer to making it sing.
Twittering birds: (i.e. high pitch fast vibrato) - this is easy - as I opined in Roll Call the best way to get a fast, tight vibrato is a hand position and movement with which the majority of people are intimately familiar. A little trickier is simultaneously dipping the left hand in and out of the ring to give a panting intonation to the voice. I have yet to consider low moans beyond a cursory tryout, but that too seems feasible, so that's a step towards recreating that scene from When Harry Met Sally.
Well, for a while I considered this (as one would), and then I thought about an idea I met on Theremin World - World Thereminisation, and I thought "Sex sells." The world may not particularly need yet another sexy pop video, but the idea of a moodily lit video of an attractive young thereminist in a suitable decollete dress making a theremin sing like Donna Summers doing Love to Love You Baby, having adjusted her gestural techniques to emphasise the sensual nature of the instrument and echoing the emotions of the song in her facial expressions sounds like it would be popular to a fairly broad audience. And, with a bit of luck, just sufficiently suggestive to be banned outright in those areas of the world where a more delicate sensibility prevails, which is always good for ratings. ;-)
So, back to play. Lets plug it into my iBook, to which ends I had purchased an UA-1A USB Audio Interface - a very basic entry level device, the iBook not being equipped with Audio In. I powered up garageband and, after a bit of fiddling with preferences obtained a very faint sound from the theremin. I think I need to feed the signal through my amplifier first, but that requires another cable, so next time I go to the shops in Watford. Might be a while. :-(
Still, enough signal to play with a bit. I had found a neat little $5 app called WaveWindow to turn my mac into an oscilloscope, so I now know that the sine-wave setting produces a sine-wave, and the saw-tooth setting chops the bottom off it. I also got another app at the same time that indicates if a note is on pitch or not, but that is for later on.
I did not play long with garageband, but I boosted the signal with it to fairly audible levels on my usb headset (yes the ibook does have a headphone socket, but I wanted a mike on it for skype) and I learned that it responds well to some filters, and not so well to others. (From photoshop I have learned that some filters require particular sorts of images
