JamTracks by JamKazam are the best way to play or sing along with your favorite songs. Far better than traditional backing tracks, our JamTracks are complete multitrack professional recordings, with fully isolated tracks for each part of the music - lead vocals, backing vocals, lead guitar, rhythm guitar, keys, bass, drums, etc. And our free apps and Internet service are packed with features that give you unmatched creative freedom to learn, practice, record, play with others, and share your performances. With our iOS app, you can: * Choose your favorite songs from our catalog of 3,700+ top hits * Listen to just the single part you want to play or sing to learn it * Mute the part you want to play or sing to create your own custom backing track * Slow down playback to practice without changing the pitch * Change the song key by raising or lowering pitch in half steps With our free Mac and Windows desktop apps, you can also: * Use MIDI with VST & AU instruments for keys, electronic drums, more * Play online live and in sync with others from different locations over the Internet And you can also access your JamTracks from a standard browser, and export your custom mixes as mp3 files to use anywhere outside the JamKazam ecosystem. Get your first JamTrack absolutely FREE to try it out with one of your favorite songs. After that additional JamTracks are only $1.99 each for a perpetual license (much like an iTunes digital download).
