"The Generator Organ is an off-grid crank powered self-amplified electronic organ. The organ derives all the power it needs to function in real time from a human powered hand crank embedded in the side of the instrument and needs no external sound system to play it. Volume and timbral characteristics can be performed intuitively using speed of cranking and the entirely analog circuitry allows for polyphonic/melodic performance using a top-octave division scheme."
