Despite profound limitations, the Casio VL-Tone VL-1 has become, at least for some, a desired vintage synth.
The Casio VL-1 VL-Tone, released in 1982, combines a calculator, synthesizer, and sequencer. The synthesizer is monophonic, lofi, and has pretty cheesy presets.
Even the lack of MIDI, the horrible sequencer and terrible preset rhythms, though, did not keep the VL-Tone from finding its place in songs like Trio’s Da, Da, Da.
Today, it’s desirable as a portable instant 80’s soundbox.
