About

Strumetra Studio

Features

Practice guitar with your own sheet music and TAB, build chord changes, keep time with a metronome, and create drum backing patterns. Strumetra Studio brings four practice tools together without an account, ads, or score uploads. SCORE: READ, PLAY AND LOOP Open Guitar Pro, MuseScore, MusicXML, MIDI, CAPX and AlphaTex files. Choose a part, adjust tempo, and repeat difficult passages with bar loops and count-in. Follow notation, tablature and fingering as you play along. Recent files stay within easy reach without covering your score. CHORD TRAINER: BUILD FLUENCY Create and reorder chord progressions. Manual mode offers Previous and Next; Timed mode advances at your chosen tempo; Audio Trigger advances when local microphone input crosses the configured threshold. See the current chord and the next change together. METRONOME: FIND YOUR PULSE Set BPM, use Tap Tempo, choose a time signature and sound, and configure accents and count-in. Volume and Mute respond during playback. DRUM MACHINE: MAKE A BACKING PATTERN Start with a groove or edit the seven-track step sequencer. Choose a kit, adjust tempo and swing, and mute individual tracks. Add drum or metronome accompaniment to score and chord practice. A WORKSPACE THAT FITS Score, Practice, Rhythm and Settings use a consistent layout. Playback controls remain available while you open Options or Settings. Choose Light, Dark or System appearance. iPad uses a landscape workspace with room for notation and controls. YOUR FILES STAY LOCAL MuseScore MSCZ and MSCX files use the built-in importer; no external converter or MuseScore installation is required. Audio Trigger analyzes microphone input locally while running. Microphone audio is not recorded or transmitted. Scores stay on your device. No analytics, advertising or runtime cloud account. OPTIONAL LED FRETBOARD Add visual guidance with supported Bluetooth LED fretboards compatible with Fret Zealot and Fret Zealot 2. Practice tools also work without fretboard hardware. These are third-party compatibility marks. Strumetra Studio is independent and is not affiliated with, endorsed by or sponsored by their owner. Drum Trainer and MIDI drum-hit scoring have moved to the separate StickSignal app. Drum Machine remains in Strumetra Studio. Bring your own supported score files. The interface is in English. Not all imported formats contain fingering information. Audio Trigger detects sound attacks, not chord correctness.
