## What is SUS4 Backing Tracks?

A band in your pocket. Ready to jam.
Backing tracks for blues, jazz, rock, funk and pop, ready to improvise over.
Change key and tempo on the fly. Nothing streams, so the band works offline too.

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. No internet required during practice.
