Karaoke, but for your instrument. KaroKowe Jam turns songs into backing tracks you can step into. Every song in the catalog is separated into stems - vocals, drums, bass, and more - and each stem sits on its own knob. Turn your instrument down to zero and the band keeps playing. You bring the missing part. THE MIXER - One knob per stem. Mix the band around the way you practice. - Mute the part you play - bass players drop the bass, drummers drop the drums. - Simple transport: play, pause, and go again. THE CATALOG - Browse songs that are ready to play, split into stems. - Search, favorites, top voted, and discovery feeds. - The community decides what gets split next: vote a song past the quorum and it becomes a backing track for everyone. RECORD YOUR TAKE - Record yourself playing over the mix. - Takes stay on the track, ready to replay and compare. MEET ROADIE Roadie is the in-app practice assistant for bass and drums - techniques, song suggestions, practice routines. Roadie runs on-device: your conversations never leave your iPhone or iPad. SEMITONES Semitones are the in-app currency. You earn them by taking part and spend them on extras like additional stem controls and recording. Top-ups are available but optional. ON iPHONE AND iPAD - Practice anywhere - the mixer works great with headphones. - USB-C and Lightning audio interfaces supported for playing along. - The same account and catalog as KaroKowe Jam on Mac. KaroKowe Jam is part of the KaroKowe family from the SplitFire AI suite: Karaoke KaroKowe removes the vocal so you can sing. KaroKowe Jam removes your instrument so you can play. Pick a song.
