Format
Message Format: BnH 0BH vvH
n: MIDI Channel Number
vv: Value
Send
See "1.3.3 MIDI Send by Assignable Buttons".
Receive
Receipt changes the part volume level.
How this message differs from Volume (07H)
Though this message is operationally identical to that of "9.5 Volume (07H)," the purposes of the two messages are different.
This message is used, for example, for crescendo/decrescendo, and other forms of expression while playing. "9.5 Volume
(07H)" is normally used when you want to make a fixed change in volume level.

General Use Controllers 1 through 8 (10H through 13H, 50H through 53H)

These messages are used to control DSP operation.
Format
Message Format: BnH 10H vvH
Send
Sent when a DSP parameter value is specified by a zone edit operation.
Receive
Receipt changes the value of DSP Parameter 7 [0 to 7] (7-bit parameter) assigned to the part specified by the MIDI Channel
Number. For details about parameters, see "21.3 DSP Parameters".
Any message received that corresponds to the parameter of a number not being used by the currently selected DSP is ignored.
Note 1:
Received values and parameter setting values
The range of the value of each DSP Parameter 7 array element depends on the selected DSP or array number.
Unlike manipulation of a DSP parameter using a System Exclusive Message, a value received by this control change message
is always in the range of 0 to 127, but the range is changed in accordance with the setting range of the applicable parameter
setting. Because of this, it is impossible for a value to be outside of the range.
Conversion to the parameter setting value from the value received with the message can be represented in general terms
by the expression shown below.
Parameter Setting Value = Parameter Minimum Value + (Parameter Maximum Value - Parameter Minimum Value)
For details about Parameter 7 of each DSP, see the explanations under "VI DSP Parameter List".
