SUS4 Backing Tracks

About

A band in your pocket. Ready to jam. SUS4 Backing Tracks gives you jam tracks for every key, every common style — the kind of tracks that make practice feel like a real musical situation rather than an exercise. Transpose to any key, shift the tempo up or down without pitch change, and loop a section to drill a particular passage as many times as you need. Stem isolation lets you pull individual elements of the backing — take out the bass to work on your bass lines, isolate the chords to practice improvising over them without distraction. Play along, capture the session directly in-app, and review it afterwards. • Jam tracks for every key and common styles • Transpose to any key with pitch-accurate playback • Tempo shift without pitch change • Loop sections for focused repetition • Stem isolation — remove or isolate individual instruments • Subscribe monthly, or unlock the full SUS4 suite forever: 40+ tracks, stem isolation, transpose, tempo shift, and looping All audio runs on-device.
