Themin, also known as aetherphone or etherophone, is an instrument used for music. There have been many versions of this instrument, from the simple model with speaker and controller to the more complex models that include variable modulation, such as the ones created by Bob Mog.
RolloSONIC now allows us to install a theremin into our computer. However, instead of holding it in one's hands we can use the mouse to control it. All kinds of oscillators and processors will be at your disposal (for audio entry and exit), effects, and an oscilloscope to control volume.
If you are not familiar with modular synthesizers it can be difficult to use the program. However, once you understand how the signal flow works you'll be able to create a controllable voice with your micros signal or mouse within minutes.
