Electronic Musical Instrument 1870

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. The instruments was light and portable and built in a 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 of the sound wave could be altered to give a more staccato effect or softened to give a more string like sound, the timbre of the sound could also be altered.
