SK-51 is an all-in-one keyboard inspired by the Casio SK-1 (and his brother the SK-5), a 8-bit lo-fi keyboard from the 80’s, with sampling features and onboard drum machine.
Called the poor man's sampler at the time, this keyboard was a real instrument and has been used by many major artists such as Fatboy Slim, Portishead, Autechre and Nine Inch Nails.

As some of us at Fingerlab compose their first songs with it when they were kids in the eighties, we wanted to bring back to you this particular feeling from the past, so we created the SK-51.

We recorded all the instruments and drums notes, one by one with a professional audio quality (16bit/44KHz), we recreated the sampling features, and we transcribed all the demo drums patterns.
We also added the sounds from the Casio VL-Tone, a keyboard older than the SK-1 but nevertheless famous.

With its nice and true to life interface, many instruments (Trumpet, Flute, Piano, Vibraphone, …), 4 sampling slot and many drums patterns and sounds, the SK-51 is versatile and fun music tools.
Record your voice, start the drum box, play a chord and you got it!

Free version features:
- 3 instruments (Flute I, Piano I, Trumpet)
- 7 drums kit

We hope you’ll enjoy it!

Stay tuned!

Suggestions From A Musician to Improve This Great App

This app is great, simply for allowing us to enjoy the features of the original Casio Sampling Keyboard without having to shell out the cash for an original hardware version. My suggestions for improving this app:

1) Allow the sample to play at the same speed regardless of pitch.
2) Allow the ability to choose different attack envelopes for the type of sound the user is trying to achieve (especially pads).
3) place more of the yellow trigger pads, like on the SK-5.
4) figure out a way to prevent the samples from clicking when they start over in “loop” mode.
5)figure out a way to allow sounds to sustain.

Otherwise, this is an app with a great future! Worth your time/ money.

Something new

I haven’t tried the full app even though it could have possibilities. With what I tried I’m stuck with Will this app be worth it or just another app collecting gigabytes.

App Crash - edit

Update - The developer responded directly to the concern and rectified it immediately. One star review is now easily a 5 star review. The app is perfect.

When you try to hit any of the sample buttons or make an attempt to record a sample, the app crashes. Not cool to $5 to not have access to the apps ultimate selling point.

Developer Response ,

Sorry for this issue, we already have sent an update fixing all this issues, it will be available in a few days.
