Professional producers use a variety of tools to create beats. These tools include digital audio workstations (DAWs), samplers, drum machines, MIDI controllers and sequencers. DAWs allow producers to record and mix audio, while samplers allow users to sample and manipulate sounds, and drum machines and sequencers provide the rhythm for a track. MIDI controllers can also be used to control virtual instruments and manipulate sounds. Producers also use software plugins to add effects and synthesizers to their beats.
