The VL-1 was actually the first instrument of Casio’s VL-Tone product line, and was also a functioning calculator! VL-1 sounds created by filtered squarewaves with varied pulse-widths or vintage Pulse Width Modulation (PWM).
An advanced unit, it featured a programmable synthesizer which provided for oscillator waveform and ADSR envelope (VCA) selections.
German band Trio used the VL-1 in the hit song from the 80′s “Da Da Da”.
