The free version includes 3 instruments, 14 drum kits, 4 sampling slots, 6 drum pads, a drum pitch-bend ribbon, a full mixer, MIDI, Audio Unit exposure, AudioBus & Inter-App Audio support, and Ableton Link. The full version (in-app purchase) unlocks 19 instruments, 14 drum kits, 21 demo patterns, 5 effects (TubeAmp, Phaser, Delay, Reverb, Compressor), and live recording.

User Reviews

Overall, SK-51 is praised for its nostalgic Casio vibe, intuitive UI, and solid recording features, plus reasonable pricing and GarageBand usefulness. The main drawbacks are paywalls gating core features, stability issues and crashes during sampling, and unreliable output playback. When fully unlocked, many reviewers feel it’s worth the price, but frustration remains from not being able to test sampling before buying and from bug-related interruptions.
Pros
  • Nostalgic Casio SK-1 vibe with authentic retro sounds.
  • Easy-to-use, classic and friendly UI (resizable).
  • Strong recording/sampling capabilities that are a highlight.
  • Affordable price and good value when fully upgraded.
  • Good GarageBand compatibility and usefulness for GarageBand users.
Cons
  • Free version is largely useless due to paywalls; core features require purchase.
  • Crashes and instability around sampling/recording, especially after upgrades.
  • Output playback issues; sometimes samples don’t audible or playback is unreliable.

Dude, everything here is. Great! I love the old analog sounds, too bad most of it his behind a paywall.

Really wonderful and powerful app. One request: can you please make this Bluetooth compatible? It would be so rad to use my stereo speakers as a playback option. This would open up a wide array of possibilities. It works with earbuds but not Bluetooth speakers for some reason. Other than that, I love it!
