Controllers 80-97
Decimal Hex Name Applications and notes
Registered and Non-Registered Parameters: Controllers 98-101
Decimal Hex Name
Registered and Non-Registered Parameters combine three commands. The first two define the Parameter to be
changed: the first is the Parameter numberÕs Least Significant Byte (LSB), and the second its Most Significant Byte
80-83
50-53 General Purpose #5-#8 Similar to 16-19 and 48-51.
The PC88 uses #83 to set Algo-
rithms for the Internal effects processor.
84
54
Portamento Control
When Portamento Switch (41H) is turned on, and Portamento
Time (05H) is not zero, the value of this Controller is the
number of the note at which the glide will
start
.
85-90 55-5A Undefined
The PC88 uses #90 to set Algorithms for the VGM effects
processor.
91
5B Effect 1 Depth Most commonly used as an effects “send”, but can be used for
any effects-related control. Roland GS instruments use this as
a reverb send.
The PC88 uses this for “Reverb Wet” con-
trol of the Internal effects processor.
92
5C Effect 2 Depth
The PC88 uses this for “Reverb Wet” control of the VGM
effects processor.
93
5D Effect 3 Depth Roland GS instruments use this as a chorus send.
The PC88
uses this for “Effects Wet” control of the Internal effects
processor.
94
5E Effect 4 Depth
The PC88 uses this for “Effects Wet” control of the VGM
effects processor.
95
5F Effect 5 Depth Similar to 91
96 60
Data Increment
The transmitter is a button, usually labelled “+1” or “Yes”, so
this is a “unipolar” controller, with only one value: 127=On.
Similarly to Data Entry (06), the receiver is any parameter
change, and this can be used in conjunction with Registered
and Non-Registered parameters (98-101).
97 61
Data Decrement
The opposite of 96, the transmitting button is labelled “-1” or
“No”. Receivers are the same.
98 62
Non-Registered Parameter Least Significant Byte (LSB)
99 63 Non-Registered Parameter Most Significant Byte (MSB)
100 64
Registered Parameter Least Significant Byte (LSB)
101 65 Registered Parameter Most Significant Byte (MSB)
