PCM 80 MIDI Implementation Details
Range Decode 22
The value is used as a lookup to the following valid gain assignments.
Off, -24.0db, -18.0db, -14.5db, -12.0db, -10.1db, -8.5db, -7.2db, -6.0db, -5.0db, -4.0db, -3.3db, -2.5db, -1.8db, -1.0db,

Range Decode 23
The value is used as a lookup to the following percent assignments.
-100, -93, -87, -80, -73, -67, -60, -53, -47, -40, -33, -27, -20, -13, -7, +0, +7, +13, +20, +27, +33, +40, +47, +53, +60,
+67, +73, +80, +87, +93, +100
Range Decode 24
The value represents time in increments of 1 millisecond.
Range Decode 25
Simple. The value is displayed without units, displacement or multiplier.
Range Decode 26
Room Size. The value represents a reverberation room size. 0 indicates the smallest room size which is
4.0 meters. Each successive value is an increment of 0.5 meters.
Range Decode 27
Duration. The value represents a time starting at 140 milliseconds with increments of 5 milliseconds.
Range Decode 28
The value represents a percent value in increments of 2%.
Range Decode 29
Spread. The value to display translation for Spread is not straightforward because it is dependent on the
values of the RvbDesign Link and RvbDesign Size parameters. (Spread is only found in the Chamber and
Infinite reverbs, therefore in the three algorithms: Chamber, Infinite and M-Band+Rvb).
Spread always has a range of 0-255. The value is used directly. If the value of the RvbDesign Link
parameter is Off, then the displayed Spread is the value 0-255. If the RvbDesign Link parameter is On,
then the Spread value is scaled by the following integer math formula:
((RvbDesign Size value + 16) * RvbDesign Spread value)/160
Example:
Range Decode 30
Percent. Similar to range decode 9, the value is displayed as a percent. Zero percent is displayed as "Off".
Range Decode 31
Similar to Range Decode 26. The value is displayed without units, displacement or multiplier. A value of
0, however, is displayed as "Off".
Range Decode 32
The value is used as a lookup to the following 81 level gain assignments.
-85db, -81db, -79db, -77db, -75db, -74db, -73db, -72db, -71db, -70db, -69db, -68db, -67db, -66db, -65db, -64db,
-63db, -62db, -61db, -60db, -59db, -58db, -57db, -56db, -55db, -54db, -53db, -52db, -51db, -50db, -49db, -48db,
-47db, -46db, -45db, -44db, -43db, -42db, -41db, -40db, -39db, -38db, -37db, -36db, -35db, -34db, -33db, -32db,
-31db, -30db, -29db, -28db, -27db, -26db, -25db, -24db, -23db, -22db, -21db, -20db, -19db, -18db, -17db, -16db,
-15db, -14db, -13db, -12db, -11db, -10db, -9db, -8db, -7db, -6db, -5db, -4db, -3db, -2db, -1db, +0db
52
RvbDesign Size value 103 (55.5 meters)
RvbDesign Spread value 147
((103 + 16) * 147)/160 = 109
