What is MIDI?

Applies to: All products

MIDI (Musical Instrument Digital Interface) is a data communication protocol which can be transmitted via USB or 5-pin DIN cables for the purpose of integrating with, controlling and communication functional commands to software programs and extension. MIDI can contain note data such as Pitch, Velocity, Note on/off, Aftertouch among many other functions.

MIDI is inaudible in its simplest format. MIDI data can be translated into audio by a sound module, such as a hardware or software synthesiser, VST, keyboard or Drum Machine.

Control Surfaces, Synthesisers and Sequencers use MIDI to communicate messages containing note data and controls for various parameters. Some complex MIDI messages require advanced configuration to be sent and received correctly, however most keyboards simply transmit note data containing Pitch, Velocity and Note on/off. This note data is used to trigger a sound module.

For example, creating an external MIDI track in a DAW such as Logic or Ableton will record and transmit MIDI data, though it will not be audible unless received by a Sound Module. If the track is sending MIDI to a sound module, such as a synthesiser or VST, the MIDI data will trigger the module to create a sound in response to the pitch and velocity of the MIDI message.

The correct setup procedure to configure a MIDI controller or keyboard with a sound module varies depending on the specific device, software and connections you’re using.
