What Is Midi - Roland UM-ONE 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 UM-ONE and is received by the computer's software sound module,
and then the software sound module plays the note "C. "
"C" key is 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.
* DAW software is a term that refers to music production software, such as SONAR.
