The method may comprise playing back a first midi segment of a song, the first midi segment comprising a first midi sequence repeated a predetermined number of times, transitioning to a second midi segment of the song after the first midi sequence is repeated for the predetermined number of times unless a first foot-operable switch is triggered, receiving a first activation command during the playback of the first midi segment and in response to the first activation command, modifying the predetermined number of times the first midi sequence is to be repeated wherein the first activation command is triggered based on, at least in part, a duration and frequency of a user application of the first foot-operable switch.
