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
The Therevox ET-4.1 is an analog continuous pitch instrument inspired by the interface of the rare Ondes Martenot.
Each oscillator has six different waveforms, including the classic sine wave of the Electro-Theremin and the Ondes Martenot’s unique octiviant and white noise settings. Each oscillator can be tuned separately, or synched to create intervals or interesting harmonics. Oscillator 2 can also be set to a consistent note or used as an LFO to modulate the filter. The internal low-pass filter with variable cutoff frequency is used to shape the sound and this can also be controlled with an external expression pedal or CV source.

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.
Therevox has introduced the Therevox ET-4 – a new continuous pitch analog synthesizer that is expected to ship in January of 2012.
The Therevox ET-4 is inspired by the Ondes Martenot’s “au ruban” controller .Pitch is controlled by moving an adjustable finger-ring, while amplitude is controlled by two pressure-sensitive keys.
The ET-4 can interface with external synthesizer gear through Control Voltage (CV) outputs for the ring controller and amplitude keys.
A wide range of sounds can also be created with the ET-4’s dual analog oscillators, each with 6 waveforms and 6 octave positions, along with low-pass filtering and real spring reverb. The ET-4 plugs directly into an amplifier and has a separate output for a tuner, for easy and silent tuning changes.
