For everyone who plays an instrument. Turn your sheet music into an instrument. Tap notes directly to perform. Enjoy rhythm practice, sight-reading, ear training, and simple song ideas with ease. β€’ Play single notes and chords, with # / b by tapping the left or right edges β€’ Tap length roughly changes note duration β€’ Transpose β€’ Metronome β€’ Recording & Playback β€’ Add takes to layer your performance β€’ Change the key and tempo during playback β€’ Performance data syncs with the companion app β€œKalimbar” β€’ Effects β€’ Zoom in and out of the score β€’ Zooming out enables a wider playable note range. 【FAQ】 Q. I’m concerned about the response time (latency) between tapping and hearing the sound. A. We recommend using the device’s built-in speaker or a wired connection (earphones/headphones via USB-C/Lightning). Note: Bluetooth (wireless) audio is more likely to introduce delay by design. Q. When I use 3-finger (or more) multitouch, the sound or behavior becomes unstable. A. If Settings > Accessibility > Zoom is ON, iOS/iPadOS prioritizes its built-in three-finger gestures, which can interfere with this app’s controls. If needed, please temporarily turn Zoom OFF.
