Object, Instrument, Technology

The Sonde is a studio-oriented musical instrument designed by Canadian physicist Hugh Le Caine and built in the National Research Council of Canada’s (NRC) Electronic Music (ELMUS) Lab in Ottawa, Canada. It was created to facilitate experimentation in additive electronic sound synthesis. Unlike subtractive sound synthesis, in which a complex waveform is “shaped” by filtering or removing different frequencies, additive synthesis requires building up a complex waveform through the simultaneous introduction of multiple simple waveforms.

The Polyphone is a performance-oriented musical instrument designed by Canadian physicist Hugh Le Caine and built in the National Research Council of Canada’s (NRC) Electronic Music (ELMUS) Lab in Ottawa, Canada. It is the world’s first known keyboard-based electronic synthesizer that allowed for multiple notes to be played at once. Its name, Polyphone, is derived from this polyphonic capacity. It permitted musicians, for the first time, to play a synthesizer as they would a piano or organ: with two-hand accompaniment and multi-note chords.
