Discover UnitBasse.
69 scales, the whole neck.
Pick a scale and a root note: every note shows up on the fretboard, with its name, its interval or its degree.
Harmony at your fingertips.
Chords of the scale, triads, arpeggios and the circle of fifths: see and hear how the scale is built.
An accurate, pedal-style tuner.
Needle or strobe, offset in cents, reference from 430 to 450 Hz. The iPad's microphone is enough.
A real musician's metronome.
It floats above every tab: 30 to 300 BPM, 20 time signatures, subdivisions and Tap Tempo.
A bass amp, in real time.
Plug in your bass, put on your headphones: 8 amps, 5 cabinets and 7 effects, set up like real gear.
Scales
The fretboard,
finally readable.
69 scales in 12 families, every root note and 4 tunings. From the Dorian mode to the altered scale, the fretboard shows you everything.
A color for every role.
Root, third, fifth, seventh: the structure jumps out at you.
Fingerings.
The right finger on every note, and the scale played on real bass samples.
Harmony
Understand what
you play.
Under the fretboard, the Harmony panel opens four tools to go from the scale to the music.
Chords of the scale.
The seven chords, block or arpeggiated, with their positions on the fretboard.
Triads.
Major, minor, diminished, augmented, on every string pair and for every root.
Arpeggios.
Four-note arpeggios across the whole neck, then position by position.
Circle of fifths.
Tap a key: you hear it, with its key signature, its relative and its chords.
In tune.
And always in time.

Frequently asked questions.
How do I plug my bass into the iPad?
With an audio adapter that has an instrument input: a USB interface or a jack adapter. For the tuner alone, the iPad's built-in microphone is enough.
Why do I need headphones for the amp?
Without headphones, the sound comes out of the iPad speaker and back into the microphone: that's feedback. Plug in your headphones before turning the amp on.
Why does the amp pause while I tune?
The tuner and the amp both use the audio input. Opening the Tuner pauses the amp, which starts again by itself when you leave.
Which iPads are supported?
Any iPad running iPadOS 16.4 or later, in portrait and landscape.
How is it different from UnitBasse for Mac?
Scales, tuner and metronome are the same. The iPad amp keeps the 8 models and 5 cabinets, with 7 effects. The Mac adds the full 22-effect pedalboard, the ability to load your own Audio Units plugins (not included), sound presets, audio device selection and keyboard shortcuts. The two apps are sold separately.
Do I need an internet connection or an account?
No. UnitBasse works fully offline, with no account. The microphone is only used for real-time sound processing: nothing is recorded or sent.
Why a one-time purchase and not a subscription?
Because UnitBasse is a tool, not a service. Buy it once, use it forever.
