* Any number is OK since the device number for the
WF192XG soundcard is fixed to “All”.
For parameters with data size of 2 or 4, transmit the
appropriate number of data bytes.
When sending the parameter change messages
consecutively, be sure to leave an appropriate interval
(if the time base is 480, ca 5 clocks) between the
messages.
EXAMPLE OF PARAMETER CHANGE
1. To change reverb effect type to Stage 1, first check the
Effect Type List to identify the MSB and LSB numbers; for
Stage 1 Reverb effect type numbers are MSB = 03, LSB =
00.
Next, check the Address in Table 1-3 for the REVERB
TYPE parameter; in this case the address is High, Mid,
Low = 02, 01, 00, respectively.
Apply these to the 2.1.3 XG Native Parameter Change list
as follows:

When this data is received, the WF192XG soundcard will
change the effect type to Stage 1 Reverb.
* Any number is OK since the device number for the
WF192XG soundcard is fixed to “All”.
2. To change the effect Dry/Wet balance of Stage 1 to 50%
each, first check the Effect Parameter List, parameter
number 10, to identify the Dry (50%)/Wet (50%); in this
case the Dry=Wet value is 64 (hexadecimal 40).
Next, check the Address in Table 1-3 for the REVERB
PARAMETER 10; in this case the address is High, Mid,
Low = 02, 01, 0B, respectively.
Apply these to the 2.1.3 XG Native Parameter Change list

message, be sure to leave an appropriate interval before
the subsequent message.
