< Modifying values >

Since the Speed parameter has only two values, Slow and Fast, the lower half of the range (00H -- 3FH) will select Slow, and the upper half (40H--7FH) will select Fast.

B0 10 00	Speed	→	Slow

B0 10 3F	Speed	→	Slow
B0 10 40	Speed	→	Fast

< Modifying the value >

The Feedback parameter changes in 2% steps, with 40H as the center. (For the correspondence between hexadecimal values and parameter values, refer to the table on p.183.) Since Effect Control Depth is set to -100%, increasing control change values will cause the value of the Feedback parameter to decrease.
