Drawer : a panel board at the left side where the musician plays the “touche d’expression”, chooses the timbres and the loudspeakers.

« Haut-parleur principal » : it is a standard loudspeaker.

Keyboard : this monophonic keyboard with a variable-frequency oscillator on which each key can be used to produce vibrato is controlled much in the same way as it is on cello.

« Métallique » : source of sound amplification where a gong
is made to vibrate by means of a motorized amplifier.

Monodic/monophonic : like the human voice or the flute,
the onde is a monodic instrument.

“Palme” : source of sound amplification where strings tensed along each side of the loudspeaker are made to vibrate by means
of a motorized amplifier.

“Reverb” : source of sound amplification where springs are made to vibrate by means of a motorized amplifier.

Ring : this other way of playing (beside the keyboard) controls
a potentiometer which can produce perfect glissandi.

Timbres : waveforms you can combine.

“Touche d’expression” : it is a potentiometer which offers very subtle control over dynamics, articulation and attacks.
