Build a song one loop at a time. A looper and multitrack overdub tool for guitar, vocals and anything with a mic. Layer parts, keep them in time, and export stems when the idea is worth finishing. SUS4 Loop Builder is a multi-track looper for building song ideas from scratch. Record a bass line into the first layer, layer a chord progression over it, add a melody on top, and keep going until the idea has a shape. Each layer has its own level and effect controls so the mix develops as you build. When you have something, export the full mix or individual stems to your DAW for proper production. The loop library saves your builds so you can come back to them, reference them, or share a stem with a collaborator. โ€ข Multi-track looping โ€” record and layer on top of previous loops โ€ข Per-layer level and effects controls โ€ข Loop library for saving and revisiting ideas โ€ข Stem export โ€” export individual layers or the full mix โ€ข Multi-track export to your DAW โ€ข Subscribe monthly, or unlock the full SUS4 suite forever: unlimited loops, multi-track export, per-layer effects, and the full loop library All recording stays on your device.

This app is useful for repeatedly practicing specific sections when practicing an instrument or singing, or when learning music by ear. You can record and layer your own performance while playing back a track, change the playback speed, place markers so playback starts from specific points, and set loop playback for selected sections. It can also integrate with your Apple Music, allowing you to use songs from Apple Music as practice tracks. For music files imported from Files, it also supports a 10-band EQ, so you can adjust the bass and treble or focus on listening to only a specific frequency range. To make practice even more productive, the app includes a variety of helpful features: * A setlist feature that lets you create practice lists for upcoming performances * A calendar feature that shows your practice history * The ability to add events to the calendar and keep notes for the day of a performance * A countdown feature for upcoming events to help boost motivation * Reminder functionality to help you stay consistent with daily practice * A high-performance metronome that supports multiple measures with mixed time signatures and note values * A tuner and tuning fork feature that supports 440Hz, 442Hz, and other pitches * The ability to attach PDFs and photos, with trapezoid correction for photos so they can be neatly stretched and saved as rectangles * The ability to annotate PDFs by hand or with Apple Pencil * The ability to leave notes for each song * iCloud sync, so you can save settings and sync them across multiple devices Pro Features * Removes the limit on the number of saved metronome settings and unlocks additional sound options beyond the default tone * Unlocks PDF sharing * Removes the limit on saved recordings * Removes ads We hope this app will help anyone aiming for more precise performances in all kinds of musical settings, including concerts, live shows, recitals, meetups, solo performances, ensembles, daily practice, and the real stage.
