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.
Many MIDI messages are expressed in hexadecimal or binary numbers. Hexadecimal numbers may include the letter “H” as a 
suffix. The letter “n” indicates a certain whole number.
The chart below lists the corresponding decimal number for each hexadecimal/binary number. 
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.
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 35. 
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 38. 
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 This synthesizer’s tone generator and sequencer blocks handle different MIDI events. These are listed separately in the MIDI Data Format as well as in the 
MIDI Implementation Chart.
