In grand celebration of International Joke Day 2024, we at Caelum used our incredibly intelligent minds to bring you our first sampler; King Key. Gone are the days when you were left begging for high quality one-shot keyboard samples, now you can get King Key. Anywhere in the world you can now play the sounds of a keyboard, on your keyboard. We also blessed you with the sounds of a MIDI keyboard, a typewriter and 4 produced kits as our generosity knows no limits. Click, Clack, Svvvvt, B-ding, cha-cuh, fshhhh. With 9 instruments and 11 presets at your finger tips you can finally be the person your parents wanted you to be, a King Key one. Using proprietary high-detailed sampling techniques, which are sadly too complex for you to understand without demonstrative play-dough, we have captured the essence and spirit of a vintage Imperial typewriter, a Modal Cobalt8X and a Generic USB keyboard. We then took these beautiful, inspirational samples and produced them into some juicy, expressive kits for your pleasure. King Key is designed as an AUv3 plugin, meaning it works within iOS and iPadOS hosts such as Logic Pro, GarageBand, Cubasis 3, AUM and Beatmaker 3. King Key also works as a standalone instrument.
