Neoharp

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 Android device (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.
Works with most Android devices that support MIDI over USB.
