This is a virtual mouse-controlled theremin. Unlike a standard analog theremin, which typically has a sinewave oscillator and some basic vibrato, SpaceTheremin lets you choose from six different oscillator types (sine, square, triangle, sinc, saw, and pulse). The same waveforms can also be used for vibrato.

It has an adjustable pitch range and checkboxes that let you select whether the pitch and volume ranges are logarithmic or linear.

Use of the vibrato can result in some incredibly freaky and bizarre sounds. Set the vibrato depth (in percent) and adjust the vibrato frequency via the slider to hear the effects. A vibrato depth of 50% and a triangle waveform gives an interesting sound, for example.

Although the vibrato frequency ranges from 0.1 to 12.0 Hz in 0.1 Hz increments, checking the "modulation" box changes the range maximum to 8000. Moving this slider into the audible frequency range (20Hz and up) allows you to get strange two-oscillator frequency modulation sounds.

Another neat trick is to use the tab and arrow keys to adjust parameters while playing tones with the mouse. For instance, if the waveform is selected, the arrow keys will change waveforms in mid-tone for an interesting efect. You can also do the same with the vibrato waveform. Adjusting the vibrato frequency via the keyboard can also be handy.

This program is more for generating strange sounds than for playing actual music. As such, you may get some really horrible noises out of it.
