Funky grooves practice/jam app for all musicians, music teachers and music students no matter level, with up to 6 mixable instrument tracks. Are you tired of mostly jazz focused jam tracks, uninspiring and just not that suited for Funk/Soul/Fusion instrument practice? And do you miss the simplicity of a good funky vamp that swings, where you can just jam and not necessarily think too much about too many chord changes? You would rather jam over instrumental grooves in the style of i.e Herbie Hancock, Prince, Steps Ahead, Jeff Lorber Fusion, Maceo Parker, James Brown, Earth Wind and Fire, Donny Hathaway, John Scofield, George Benson.... Well, this might make your practice routine a bit more fun. Funky grooves with up to 6 mixable instrument tracks - Drums, percussion, Bass, pianos, guitars, click... The 8 to 16 bar sections can be transposed to all keys, instruments can be muted on a section basis to create custom arrangements - ie mute all instruments but the drums for the first repetition and add instruments on each repeat - creating classic funk build ups.
