KEEZI: Your Piano, Smarter

Your piano already sounds great. KEEZI makes it smarter.

Instantly see scales, chords, progressions, and sheet music lit directly above your keys.

KEEZI is a touchscreen controller with an LED light strip that connects to your piano via USB, responds to every note you play, and unlocks an entirely new set of creative and learning tools.

Generate chord progressions, transform any scale to the white keys, build full chords with a single note, and bring your playing to life with customizable LED effects—all on the piano you already own.

Whether you're learning music theory, practicing a new song, improvising, composing, or performing, KEEZI gives you powerful tools that simply aren't available on most pianos—and even many premium keyboards and MIDI controllers.

No apps. No subscriptions. No accounts. KEEZI is fully controlled from its built-in touchscreen, so it's always ready to use. It was designed to feel like a natural extension of your piano.

Works with virtually all USB MIDI digital pianos, keyboards, and MIDI controllers.

Display Scales

Light up scales directly above your piano keys so you can practice with confidence, build familiarity across the keyboard, and improvise without worrying about hitting the wrong notes.

Visualizer

See every note you play come to life with vibrant LED feedback across the keyboard. Personalize the experience with fade and pulse effects, custom colors, and preset palettes. Enable Velocity Lighting to expand the illuminated area based on your playing dynamics, creating a more expressive visual performance.

Chord Dictionary

Explore chords across the entire keyboard with visual guidance above every matching note. With support for any root note and 26 chord types, KEEZI makes it easy to find new voicings, build progressions, and unlock fresh musical ideas.

Animations

Whether you're practicing, performing, or relaxing, KEEZI brings your piano to life with dynamic lighting effects. Choose from a variety of built-in animations, customize the colors of each effect, or simply use a solid backlight to create the perfect atmosphere for your space.

Arpeggiator

Instantly create rhythmic arpeggios from any chord you play. Adjust the tempo, note rate, and playback style, and customize sustain pedal behavior to either hold the arpeggio or sustain notes normally.

Chord Progressions

Generate chord progressions in any major or minor key and use them as a creative backdrop for improvisation and melody writing. KEEZI can automatically sound each chord, with adjustable chord duration and the option to advance through the progression using the sustain pedal for a more hands-on experience.

Easy Chords

Turn simple key presses into full chords and explore new progressions with ease. Simply choose a major or minor key and KEEZI ensures every chord stays in scale, making experimentation effortless. Use Split Mode to play chords with your left hand while creating melodies with your right.

Move any Scale to White Keys

Play any major or minor scale using only the white keys. KEEZI automatically keeps every note in key, making it easy to improvise, jam, experiment with new ideas, and build confidence without worrying about playing the wrong notes.

Sheet Music Quiz

Build confidence reading sheet music. Practice identifying both notes and chords in both the treble and bass clef while KEEZI tracks your score, accuracy, and response time to help you measure your progress.

Works with virtually all pianos!

KEEZI is 100% compatible with virtually all digital pianos and keyboards that support MIDI. During development, KEEZI was tested with a wide variety of keyboards from major manufacturers. The included LED strip can also be trimmed to fit keyboards of virtually any size, from compact 25-key MIDI controllers to full 88-key pianos.

Every KEEZI includes a USB-A to USB-B cable for direct connection to most digital pianos. A small percent of pianos use USB-C or Micro-USB ports instead. These are fully compatible with KEEZI but require the appropriate cable (or adapter).

Have an older piano with only traditional 5-pin MIDI ports instead of USB? No problem. KEEZI can still be used with a MIDI-to-USB interface, available separately.

Even acoustic (non-digital) pianos can still use KEEZI's LED lighting and animation features for displaying scales, chords and animations. However, features that require MIDI communication—such as Visualizer, One-Key Chords, and Arpeggiator require a MIDI capable piano.
