Wood, keyboard, 13 oscillators with modulators, transistor technology (germanium transistors), tube amplifiers, opto-couplers

The 13 keys of the keyboard activate the 13 oscillators. The frequencies of the individual oscillators can be selected freely by means of potentiometers. Each oscillator has its own low-frequency oscillator and variable filter functions for structuring the sound. The system is designed to be easily adaptable to individual needs.
