App Description
SK-51 is Fingerlab's all-in-one emulation of the Casio SK-1 and SK-5 — an 8-bit lo-fi keyboard from the 80s with sampling features and onboard drum machine, available for iPhone, iPad & Mac.
Called the "poor man's sampler" in its time, this iconic Casio keyboard was used by Fatboy Slim, Portishead, Autechre and Nine Inch Nails — and now it fits in your pocket.
At Fingerlab, some of us composed our first songs with it as kids in the eighties. We wanted to bring back that unique feeling, so we built SK-51: a faithful recreation of the Casio SK-1 and VL-Tone, recorded note by note at professional audio quality (16bit / 44.1kHz).
SK-51 is a universal purchase — one buy covers iPhone, iPad & Mac.
Sample your voice, fire up the drum machine, play a chord — and you've got a track.
