Quick answer: on the Jam tab, turn the Groove selector to a style, set the Tempo knob, and press Play. The band plays your progression in that groove until you stop it.
Grooves
Ballad, Rock, Folk strum, 6/8, Shuffle, Train beat, Waltz, Four on the floor, Half-time, Motown, Boom bap, One drop, Bossa, Heartbeat and Brush ballad. The free version includes the first five; Pro opens the rest.
A band, not a click
A metronome tells you where the beat is. A band tells you how the song feels. The guitar strums the chord in the groove’s pattern, the piano holds or pulses, the organ pads underneath and the drums keep time, so you can hear whether a melody works before you’ve written a word.
Mix it the way you hear it
Four knobs set the level of each part. Want just drums and piano? Turn the guitar and organ down. Every take records each part separately, so you can change your mind later on the export screen.
