On step sequencers, musical notes are rounded into steps of equal time intervals, and users can enter each musical note without exact timing; Instead, the timing and [[duration (music)|duration]] of each step can be designated in several different ways:
* On the [[drum machine]]s: select a trigger timing from a row of ''step-buttons''.
* On the [[acid bass machine|bass machines]]: select a step note (or [[rest (music)|rest]]) from a ''chromatic keypad'', then select a step duration (or [[tie (music)|tie]]) from a group of ''[[duration (music)|length]]-buttons'', sequentially.
* On the several [[electronic keyboard|home keyboards]]: in addition to the real-time sequencer, a pair of ''step trigger buttons'' is provided<!-- for "One Key Play" -->; using it, notes on the pre-recorded sequence can be triggered in arbitrary timings for the timing dedicated recordings or performances. (See {{slink|List of music sequencers|Step sequencers (supported on)}}).

In general, step mode, along with roughly quantized semi-realtime mode, is often supported on the <!-- analog --> drum machines, bass machines and several [[groovebox|groove machines]].
