What Is Midi - Roland A-49 Owner's Manual

What is MIDI?

MIDI is an internationally recognized standard for exchanging performance information between
electronic musical instruments and computers.
For example, in the illustration below, a MIDI signal meaning "the 'C' key on the MIDI keyboard was
pressed" passes through the A-49 and is received by the computer's software sound module, and
then the software sound module plays the note "C. "
MIDI signal
Information meaning "the 'C'
key was pressed"
In this way, MIDI is used to send performance information to other instruments; for example
"the 'C' key was pressed with a certain amount of force, " "the instrument was changed to a violin
sound, " "the volume was raised/lowered, " "the pitch was raised/lowered, " etc. In other words, MIDI
is the "language of musical instruments. "
MIDI signals are merely performance instructions, therefore a MIDI sound module, such as a
software sound module, is required to produce sound.
All software sound modules and DAW (Digital Audio Workstation) software support MIDI.
MEMO
DAW software is a term that refers to music production software, such as SONAR.
