Read full descriptionHide full description
Official app for the Neoharp musical instrument. Fine-tune your sound across all three channels — Chord Buttons, Bass, and Tone Keys — with flexible, per-channel controls. Connect your Neoharp to your iPhone or iPad (via USB-C), open the app, and let your ideas flow. What you can do in the app: - Balance the volume of each channel with the built-in mixer. - Choose Chord Buttons behavior: play the chord tones on press, or switch harmony silently (no chord playback). - Disable/enable the Bass voice. - Set chord voicing and range: define the playable range, toggle inversions on or off, and choose the lowest reference note (note offset). - Toggle sustain on/off; connect an external pedal to control note sustain with your foot. And that’s not all — more features are coming in future updates! Requirements: - A Neoharp instrument is required for full functionality. Questions or feedback: neoharp@neoharp.com
