While many digital and analog hardware keyboards in the aforementioned categories of digital piano, stage piano, and synthesizer can be used as MIDI controllers if they have MIDI capability, they often do not offer the same level of software integration and number of MIDI-mappable controls as a dedicated MIDI keyboard. MIDI keyboards are often utilized by individuals who work with DAWs and software instruments, from hobbyists to professional musicians working in recording studios or concert stages.
