Sequencing software can be used to manipulate recorded MIDI data with standard computer editing features such as [[cut, copy and paste]] and [[drag and drop]]. [[Keyboard shortcut]]s can be used to streamline workflow, and, in some systems, editing functions may be invoked by MIDI events. The sequencer can set each channel to play a different sound and gives a graphical overview of the arrangement. A variety of editing tools are made available, including a notation display or [[scorewriter]] that can be used to create printed parts for musicians. Tools such as [[Loop (music)|looping]], [[quantization (music)|quantization]], randomization, and [[transposition (music)|transposition]] simplify the arranging process.

[[Beat (music)|Beat]] creation is simplified, and [[groove (music)|groove]] templates can be used to duplicate another track's rhythmic feel. Realistic expression can be added through the manipulation of real-time controllers. Mixing can be performed, and MIDI can be synchronized with recorded audio and video tracks. Work can be saved, and transported between different computers or studios.<ref>Gellerman, Elizabeth. "Audio Editing SW Is Music to Multimedia Developers' Ears".

Sequencers may take alternate forms, such as drum pattern editors that users can use to create beats by clicking on pattern grids,<ref name="Huber 1991" />{{rp|118|date=November 2012}} and loop sequencers such as [[ACID Pro]], which combine MIDI with prerecorded audio loops whose tempos and keys are matched to each other. Cue-list sequencing is used to trigger dialogue, sound effect, and music cues in stage and broadcast production.<ref name="Huber 1991" />{{rp|121|date=November 2012}}
