About
“While the Theremin is notoriously difficult to play, Léon Light in its raw, untamed form, is even more unruly, perhaps even, unplayable!”
Light is the key to taming Léon. Movement detected creates sound. Wild when unrestrained. Watchful when Focused, Tempered & Trained. Léon’s discipline is impeccable. Yet there is always the danger that Léon will devour his trainer!
* Detects motion within a field of view.
* Converts movement into pitch across the audible range
* Uses Filtering and Tempering to ‘Tame the Lion’
* Create slides, textures, and rhythmic patterns via Quantization.
* FX Box with Space—Tone touchPad & Width parameter for Real-time control.
* Quick Select Instruments. Pre-program scales, chords, and songs.
Not A Theremin!
The Theremin responds to movement within electromagnetic fields. Léon Light responds to motion detected within a visual field.
Inventor’s note:
Early demos of the prototype always elicited the response: “Oh, it’s like a Theremin!”. Clinging to the conceit of originality, I would protest and explain the differences — to no avail. Today, I embrace the comparison. 'Yes, it is like a Theremin — but even more difficult to control!'
Taming the Lion
Adjust quantization, temperament, instrument range, focus, attack style, pitch class filtration, and real-time effects. Léon can sing smooth scales & arpeggios. With proper light conditions, training and playing technique, Léon is a reliable, expressive musical instrument. Yet always remember — Léon is wild at heart.
