PTheremin is a software-based Theremin synthesizer.

This is a simple software-based Theremin written in Python. A theremin is an electronic device that uses a capacitance sensor to determine the distance between the device and the user and outputs a tone that varies based on the distance sensed. Most people are familiar with this instrument as the very sound effect used in many old sci-fi flicks. This program lets the user control the frequency and amplitude instead using the mouse.

An additional feature is the ability to limit the output frequency to only musical notes of a particular scale (diatonic, pentatonic, etc). You won't get the very sound but you will be able to play clean notes easily. You can't use vibrato in this mode unfortunately.

To get a really convincing Theremin sound it helps to run the output into a reverb effect of some sort (I use a reverb pedal and a guitar amplifier).


A Linux PC with an OSS-suported soundcard.
Python 2.3 or later.
PyGTK 2.4 or later. Might work on earlier versions but not tested.

What's New in This Release:

Fixed max volume causing clipping.
Fixed saving a recording takes forever.
Various UI improvements (colors, note labels, scales).
