Theremin

This is an awesome idea and execution of an app. Only suggestion is if the volume was easier or more practical to control. It's hard to adjust it while holding a note very still. What if you held a finger anywhere on the screen to bring the volume down? Just a thought.

Free and awesome! Best instrument known to mankind!

Way cheaper than a theremin but still fun.

Fun graphics and good sound. At 99 cents it's a pretty good value, but if you are a Theremin fan and want features, the Theremin-ator looks like it'd be the better choice. I'm thinking I should have gone with the latter. This one has a choice of three wave forms (sine, triangle, square), but you'd really only want Sine. It has a good range. Pitching the phone left to right changes note low to high. Aiming the phone down while on the left lowers the note more, while doing so on the right raises it higher. Having some echo would really bring it to life. Not having any dynamic volume control is problematic (I use the volume slider)

I've built and played all sorts of theremins and was excited to see an app for the iPhone. My major gripe is the lack of true control over pitch. Wildy jumps an octave or two when you are going for a small interval. The tracking is just not consistent. I suspect this is a short-coming of the iPhone itself, not the software. What I do like about this app is; the nice vibrato control options, the 3 different waveform options and the "chromatic" option. What I would like to see in future releases; better movement-to-pitch tracking(most important), simple reverb or delay, and filter/tone control for the waveforms.

Simple & fun. The only complaints I have are that the settings sliders don't always respond well & the iPhone goes into standby too quickly for this app. Some kind of touch control would easily fix this problem.

Hey, just in time for Halloween... some classic theremin sound effects! Sounds great, and it has range buttons for choosing either finer control or a wider range of pitches. Sounds extra-weird when you add lots of vibrato. And the animated Theremin player waves his hands at the antenna, just like you'd do playing an old school theremin. Easily worth 99 cents!

I had problems getting sound out of the app at first and had to reinstall it to get it working. Once I did that it worked. Like a real Theremin it is hard to control and find the correct pitch. I'm still struggling to play the "Good Vibrations" theremin part. The animation of Leon Theremin is fun an option for Clara Rockmore would be even more fun,
