02 / YOUR SPACE TO PRACTICE
A real Windows app with your recent tabs and settings ready for your next session. No account needed to practice.

Bring your own music. Open supported Guitar Pro 3-8 files and choose your guitar track.
Make it visible. Explore note colors, finger colors, song maps, and optional original Fret Zealot LEDs.
Keep it local. The app processes your tabs and microphone audio on your computer.
SEE THE SHAPE BEHIND THE SONG
Turn on Chord anticipation and the studio analyzes the entire selected guitar track against a built-in dictionary of open, barre, movable and seventh-chord shapes.
It looks for familiar shapes in chords and arpeggios, then considers neighboring bars to suggest more consistent finger placements and fewer unnecessary hand shifts. That makes the preview more useful when a chord is picked one note at a time.
Available in the web studio and Windows app. Analysis runs on your device. Look for Full track analyzed when it is ready.

Listen & wait listens to your guitar and holds the current target until it hears a stable matching note. Play the right note, and the tab and fretboard move on to the next one.
Use your microphone to get started. With the installed Windows app, you can also plug your guitar into your computer through a suitable USB audio interface. A clean direct signal can reduce room noise and improve recognition accuracy.
Choose your input in Audio inputs, then enable Listen & wait. Chord matching and bend-friendly assistance are available too; recognition depends on your signal and remains experimental.
The tab and fretboard show the next notes to play.
Your selected microphone or guitar interface supplies the sound.
The next target appears after the app recognizes the expected pitch.
Audio is processed on your device. The app does not record or upload your microphone audio.
FROM YOUR SCREEN TO YOUR STRINGS
