  • Step mode: On the step sequencer, musical notes are divided into steps, and each steps are recorded without exact timing. Instead, timing of each step are separately designated by order of entering steps (on bass machines), or selection of column buttons (on drum machines). Analog drum machines and bass machines often utilize this mode, along with semi-realtime mode.
