MIDI Support

The Musical Instrument Digital Interface (MIDI) enables consumers to use multimedia computers and electronic musical instruments to create, enjoy, and learn about music.

The MIDI protocol is a music description language in which every word describes an action of musical performance. Each action is stored as a binary word, and when combined, stored as MIDI files. These files can then be replayed by any electronic device that can read the MIDI file and recreate the performance using its available sound system.

Technical Specifications for MIDI:

•Recommended file size: up to 15 Kb

•MIDI instruments: 128

•Maximum polyphony: 24 voices

•Minimum duration per note: 20ms

•Maximum duration (NW dependent): 16-30 secs
