About MIDI About MIDI MIDI (Musical Instrument Digital Interface) is a standard which allows electronic musical instruments to communicate with each other, by sending and receiving compatible Note, Control Change, Program Change and various other types of MIDI data, or messages. This synthesizer can control other MIDI devices by transmitting note related data and various types of controller data. It can also be controlled by incoming MIDI messages which automatically determine the tone generator mode, select MIDI channels, voices and effects, change parameter values, and of course play the voices specified for the various Parts. MIDI channels MIDI performance data is assigned to one of sixteen MIDI channels. Using these channels, 1 - 16, the performance data for sixteen different instrument parts can be simultaneously sent over one MIDI cable. Think of the MIDI channels as TV channels. Each TV station transmits its broadcasts over a specific channel. Your home TV set receives many different programs simultaneously from several TV stations and you select the appropriate channel to watch the desired program. Weather Report News 2 1 News 2 MIDI operates on the same basic principle. The transmitting instrument sends MIDI data on a specific MIDI channel (MIDI Transmit Channel) via a single MIDI cable to the receiving instrument. If the receiving instrument's MIDI channel (MIDI Receive Channel) matches the Transmit Channel, the receiving instrument will sound according to the data sent by the transmitting instrument. For information on how to set the MIDI transmit channel and the MIDI receive channel, see page 104. MIDI Transmit channel 2 MIDI cable MIDI Receive channel 2 MIDI channel and MIDI port MIDI data is assigned to one of sixteen channels. However, we can overcome the sixteen-channel limit by using separate MIDI "ports," each supporting sixteen channels. For details, see page 107. MIDI Messages Transmitted/Recognized by this synthesizer MIDI messages can be divided into two groups: Channel messages and System messages. Below is an explanation of the various types of MIDI messages which this synthesizer can recognize/transmit. The messages transmitted/recognized by this synthesizer are shown in the MIDI Data Format and MIDI Implementation Chart of the separate Data List. n Some of the following explanations are described in a general sense, and not necessarily as how they relate to the MO. For details about the behavior of MO when receiving each MIDI message, refer to the "MIDI Data Format" and the "MIDI Implementation Chart" in the separate Data List. Appendix Owner's Manual 223
