Control change events
Control change events are used to transfer MIDI controller information (modulation, sustain,
volume, and pan, for example) to software instruments or external MIDI keyboards and modules.
•
Ch(annel): MIDI channel of an event from 1 to 16.
•
Num(ber): The number of the controller. Each MIDI controller (such as the modulation wheel
or sustain pedal) is assigned a specific Continuous Controller (CC) number (CC#1 or CC#64,
respectively). This can vary from device to device. Several controllers (apart from the two
above) are defined in the same way by most manufacturers; these standardized controllers
include volume (CC#7) and pan (CC#10).
•
Val(ue): Value of the controller. Continuous controllers have a range of 0 to 127. Switch
controllers (CC#64–CC#90) transfer two states: off (val = 0) and on (any value between 1 and
127).
•
Length/Info: Shows the name of standardized controllers defined in the MIDI Specification.
Pitch bend events
Pitch bend events are used to continuously vary the pitch. They are usually generated by a
centered pitch bend wheel or joystick on your keyboard.
•
Ch(annel): MIDI channel of an event from 1 to 16.
•
Num(ber): Fine pitch bend division (LSB: Least Significant Byte). Many keyboards transmit
a value of 0. If the pitch bend wheel has an 8-bit resolution, you see values of 0 or 64 in
this column.
•
Val(ue): The effective pitch value (MSB: Most Significant Byte), ranging from 0 to 127. A value of
64 corresponds to the half-way setting of the wheel.
•
Length/Info: The 14-bit value is displayed in this column as a decimal figure ranging from −8192
to 8191 (if your keyboard transmits 14-bit pitch bend data). The value in this column can be
edited in the usual ways.
