The OM-1 Cassette Synthesizer is an analog musical instrument built around the concept that when a continuous tone/note is recorded to tape, its pitch will change as the tape's playback speed is increased or decreased. Individual notes are playable via the 8 buttons (keys), each with a tuning knob directly above it. The volume of the notes can be articulated by using the pressure sensitive volume control - the harder its pressed, the louder the note. A three position switch controls attack/release response of the audio output - Short, Medium, and Long. CV/Gate inputs allow control over the cassette's pitch and volume from a linear (non-quantized) voltage sequencer.
While loosely inspired by instruments like the Mellotron® and Ondes Martenot, the OM-1 has a sound all its own. Because it uses a standard cassette tape as its audio source, the sound creation possibilities are endless. The OM-1 is engineered for experimentation.
