Practice your bass every day!
UnitBasse is the native macOS app built for bass players who want to PLAY. Not to record an album. Just to play better, every day.
Plug your bass into your Mac (audio interface or built-in mic), pick a preset, start the metronome, and train. That's it.
PRACTICE COMPANION
Practice mode (default): a clean sound, 5 essential effects (Noise Gate, Compressor, EQ, Chorus, Reverb), zero distraction. Open the app, play.
Advanced mode: 8 vintage amps, 4 cabinets, 22 effects, 12 presets — when you feel like crafting tone.
4 BUILT-IN MODULES

Version 1.1 turns UnitBasse into a real harmony tool for bass players.
What's New
Chord Explorer: see the chords of every scale degree right on the fretboard, with their playable positions and key notes (root, third, fifth, seventh).
Redesigned scale picker: instant search across all 69 scales, one-tap favorites, sorted by category.
Simple Mode: hide the chord section with a single switch for a cleaner view — perfect for beginners.
Customizable palette: pick your own colors for the harmonic roles shown on the fretboard, now with a legend right below the fretboard.
Metronome: four click sounds to choose from.
Reorganized settings (General, Audio, Appearance) with more breathing room, and a polished dark mode.
Improvements
Stronger VoiceOver accessibility across every module.
Clearer microphone access request.
Audio, fretboard rendering and stability fixes.
UnitBasse is still 100% native macOS, with zero third-party dependencies.
