Examples of Using Effect Controllers
Here are some examples of how effect controllers can be used.
In these examples MIDI messages are used to modify the settings.
Hexadecimal values in the < Settings > sections denote Exclusive messages, and hexa-
decimal values in the < Modifying the value > sections denote control change messages.
The Exclusive messages are given with device ID 17 (10H) (the factory setting). After the
settings in < Settings > have been made, the control change messages described in <Mod-
ifying the value> can be transmitted to modify the parameters to the desired value.
For the correspondence between the hexadecimal values and the parameter values, refer
to p.173.

< Modifying values >
Since the Speed parameter has only two values, Slow and Fast, the lower half of the
range (0–63) will select Slow, and the upper half (64–127) will select Fast.
