Reader Stephen Young created this short film, Therevox – Wood & Wires, which takes a look inside the workshop of Therevox Custom Musical Instruments.
Since 2004, Mike Beauchamp’s Therevox has made instruments in the tradition of Paul Tanner’s Electro-Theremin and the Ondes Martenot.
Their ET-4 line is controlled by moving a finger along a reference keyboard, shaped to provide tactile feedback. Dual pressure sensitive intensity keys control the amplitude of the ET-4’s two independent analog oscillators. The ET-4’s performance options are rounded out by a low-pass filter, white noise generator and internal spring reverb.
Here’s a quick demo of the Therevox ET-4.3 continuous pitch analog instrument.
This includes a 4-mode MIDI over USB output, controlling two instances of AMsynth, an assignable expression pedal/CV input and intensity key “hold” knobs. Continue reading
Giuseppe Di Cillo hacked his Gakken SX-150 to add a pressure sensitive ribbon controller, turning it into a cheap electro-theremin.
The Mod Ingredients:
- 1 50cm softpot sensor
- 2 15kh resistors
- 1 wooden board
- 2 female audio jacks
- A cable with two stereo male audio jack
- 1 3-terminal connector for printed circuit
- electric cables
Details on the Gakken SX-150 mod are available at Coagula.
This is a demo for Drawdio – a pencil that lets you “draw” instruments.
While creator Jay Silver compares it to a theremin, it’s closer to a Tannerin or Electro-Theremin. Continue reading
