Connecting to MIDI devices and applications
Musical Instrument Digital Interface (MIDI) is a standard for communicating performance information from one
piece of software or hardware to another. In Windows, you can transmit MIDI data internally between applications, or
externally to and from devices such as MIDI keyboards. In Adobe Audition, you can utilize MIDI in the following ways:
• Using the MIDI sequencer, you can import, record, and edit MIDI data, and you can output it through VSTi
virtual instruments or hardware synthesizers. (See Composing with MIDI.)
