What key are we in, what’s the chord right now, and what comes next? Scale Navigator answers that question by giving you a way to explore harmony and keep what you find. You can move through scales and chords, try things, and hear how they connect. Stay in one area or move somewhere new. When you come across something you like, you can save it. Build sequences of harmonic states and chain them into a progression or a full song. Whether you’re exploring or building, the foundation stays the same: a shared harmonic state. Once it’s set, everything can follow it. Your playing, your instruments, your DAW, or other musicians in the room. THE SCALE NETWORK Scales are arranged in a connected network: think of it like the circle of fifths on steroids. Each scale sits next to neighbors that are related, so moving between them feels smooth. Move locally for subtle changes, or jump across the network for contrast. CHORD PROGRESSIONS Every scale contains its own set of chords. You can adjust chord quality, control how roots move, and shape the voice leading. This gives you a structured way to explore chords, try ideas, and keep what works as you move through different harmonic areas. SKETCHPAD When you land on something you like, you can save it. Each saved state keeps the scale and chord together, so you can return to it, compare it, and build from it. Write music step by step by chaining together the moments you want to keep. ENSEMBLE Create an ensemble and share a link. The host controls the harmonic state. Anyone who joins stays in sync with the same scale and chord in real time. Each person or instrument can use it differently. Play directly, improvise, read notation or tablature, or route it into MIDI. It works just as well for coordinating multiple instruments on your own as it does for playing with other people. TABLATURE View scales and chords on piano, guitar, bass, mandolin, and other instruments, along with standard notation. 3D VIEW The network can also be explored in 3D, with zooming and rotation control. DAW INTEGRATION Connects to your DAW, so your session stays in sync with the current harmonic state.
