Theremin or aetherphone / etherophone is an instrument that has been used in music since the thirties, and there have been hundreds of versions over the years, from simple models with integrated controller and speaker to those with variable modulation like the ones designed by Bob Moog.

Free modular synthesizer that's easy to control

Now we have the option to have a theremin in our computer thanks to RolloSONIC, but now instead of using it with our hands, we will do it with the movement of our mouse. We will have at our disposal all kinds of oscillators, processors (for the entrance and exit of audio), effects and oscilloscope (to control the output volume).

The program can be very complex to control if you have never worked with modular synthesizers, but once you get used to how the signal flow works, you will be capable of creating a controllable vocoder with the micros signal and your mouse in a matter of minutes.
