The ‘Ondium Péchadre’ H. Péchadre. France, 1930

The Ondium Péchadre was developed in France by H.C.R.Péchadre in 1930. The instrument was a monophonic heterodyning vacuum tube oscillator based instrument built into a light and portable heart shaped box, in performance the base of the instrument rested on the players knees and the instrument was supported against a table. The six octave range of the instrument was controlled by moving a pointer around a circular calibrated dial while the left hand controlled the volume of the sound with a velocity sensitive push button device. The attack and timbre of the sound wave could be altered to give a more staccato effect or softened to give a more string like sound.
