Here’s a quick demo of the Therevox ET-4 analog ribbon synthesizer.
Inspired by the Ondes Martenot’s au ruban controller, the ET-4 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 video demo is by reader Gil Assayas, who notes, “It is a fantastic instrument with a very deep and musical sound.
“Mine had some MODs added to it, various CV ins and outs, headphones out, a pre-filter FX loop and “hold” knobs for the oscillators,” he adds. “Here’s a demo I recorded today with a few sounds. No processing was done to the ET-4’s raw output, but I used an MXR Carbon Copy delay on some sounds (the reverb is the ET-4’s built-in spring reverb).”
