Autodafe has released a free Kontakt soundset sampled from the Casio VL-1 (or VL-Tone), a small synth-calculator from the '80s, (in)famous for its sounds and rhythms.
It features the 5 original on-board sounds (Fantasy, Guitar, Piano, Violin and Flute) and the on-board rhythms at fixed tempo.
Kontakt scripting provides controls for ADSR and FX Bypass.
