MIDI MESSAGES
Polyphonic Aftertouch: hard that key is being pressed. (le. each key can send independent aftertouch
messages.)
the position of the controller. In this chart, control changes 01-07 are "continuous
controllers." (Slider or wheel-type controllers) They carry data in the range of 00-7 F am
Control changes 40-43 are on/off switch-type controllers. Data O is off, data 7F
is on.
Control changes 7A-7F are a special type of control change called Mode Messages,
and usually carry a fixed data byte. They tell the receiving tone generator how to
behave. The way in which these message are interpreted will depend on the device.
(See the MIDI Implementation Chart for your tone generator or synthesizer.)
Cn Program Change: This tells the receiving device to switch programs (memories).
Dn Channel Aftertouch: Also called "Common Aftertouch", this is found on the DX7. It indicates the
strongest pressure on any part of the keyboard, ie, the "common" value.
En Pitch Wheel : To provide finer resolution, this data is sent in two bytes, first the Least Significant
Byte (LSB) and then the Most Significant Byte (MSB). Yamaha tone generators
and synthesizers ignore the LSB.
FO System Exclusive: After FO must come an identification number which has been assigned to each
manufacturer. Yamaha's number is 43. What comes between this message and F7
(End of Exclusive )is completely up to each manufacturer (but each byte must be
between O and 7F). Yamaha uses System Exclusive messages to transmit voice am,
data, sequence data, rhythm pattern data, bulk memory data of all kinds, and many
other useful things. See the System Exclusive format chart for your device.
F7 End Of Exclusive This marks the end of a System Exclusive message.
(EOX):
F1, F4, F5, F9, FD: These are unused, and reserved for future expansion.
