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 video intro to the Therevox ET-4.1: Continue reading
Reader Ville Aho created a DIY Ondes Martenot style synthesizer, the MonotrOndes, based on a Korg Monotron. Continue reading
The video takes a look at a new instrument created by Mark Steiner, the Artemis.
The Artemis is a wind/string instrument, inspired by the Ondes Martenot. Pitch is mainly controlled by a ring attached to a loop of string. Continue reading
This video, via Mark Steiner, demos his DIY Martenot-style controller.
The Ondes Martenot, an early electronic instrument designed by Maurice Martenot in the 1920′s, offers a standard keyboard for discrete pitch control and a ring-on-a-string controller for continuous pitch control.
Here’s what Steiner has to say about his creation: Continue reading
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.
