Cakewalk's In Concert was unique in its ability to "listen" to what you played on a MIDI keyboard and alter the tempo of its accompaniment to follow your lead. Home Concert 2000 - from TimeWarp Technologies, creator of In Concert's technology - picks up where its predecessor left off. Unlike In Concert, Home Concert 2000 displays notation on screen, so you don't have to purchase sheet music separately. It can read and display the notation for any Standard MIDI file you purchase or download, though you can't print this notation from within Home Concert 2000 - for that, you'll need a separate sequencer or notation program.
