SUS4 Backing Tracks

Features
Read full description

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.
