The Swarmatron was created to produce eight tones tuned approximately to one
note, each tone slightly different in pitch to produce a complex and natural
These eight oscillators can be played with a single ribbon controller
(variable resistor) to move the pitch center up or down.
The span control expands the sound of a swarm of eight notes spread just a
few cents apart into a wide chord of equidistant pitches spread over the
entire spectrum. The player can "taffy pull" the resulting chord by using
the span control and pitch ribbon in tandem.
Swarms of sine waves evoke swarms of angels congregating. Swarms of sawtooth
waves evoke the swarming of bees. The sound of a host of voices, earthly or
unearthly, has a unique character recognized by the ear even when they are
folded together in unison.
