## What is SUS4 Backing Tracks?

A drum, bass and keys band to improvise over, in the style and key you pick.
Blues, jazz ii-V-I, funk, gospel, hip-hop, Latin, R&B, reggae and more, generated on your phone, so it works with no signal.
Fully on-device: no cloud, no account.

Choose a style and a key, set the tempo, and play. Use Solo Me to drop a part out and play it yourself: take the bass out and you are the bass player. Write a chord progression in the editor when the library does not have the changes you need.

• Tracks by style, each labeled with its key and tempo
• Change key and tempo
• Solo Me: mute a part and play it
• A chord progression editor for other changes
• Loop a section to work on it

For guitarists, bassists and keyboard players learning to solo, and anyone who wants to practice with a band instead of a metronome.

Pro, or SUS4 All-Access across the whole range, opens the full track library, key and tempo changes, looping and stem export.

Made in the UK by working musicians.
