Description
Electronica EM - 04. There is a one master oscillator in the instrument. Due to this oscillator a possibility of instrument's detuning in the process of operation is eliminated. This generator shifts a pitch of the instrument on an octave, "slalom-effect" and refines the tuning +/- 1/4. Because of split of the manual into 2 sections, the volume of each part may be adjusted."
