Four separate metronomes or timelines are available, with up to 13 subdivisions per timeline. By entering a number of beats per measure for each timeline, Quadranome can play up to 4 subdivisions against each other, with each metronome resolving to the "1". You can easily create polyrhythms such as 7/4/3, 13/4, or 11/4/5. By repeatedly listening to these complex rhythms, you can vastly improve your rhythmic vocabulary.
