 The ASR-10 sequencer had an internal 96 pulse-per-quarter-note 16 track sequencer.A 'song' was a collection of 'sequences' joined together, and users were able to jump to sequences live during a performance, in much the same way as software such as Ableton Live allows today.Songs were constructed in either a step time (note by note basis) or through live recording of the MIDI information played in.
