About Chorus Macro
When you change the Chorus Macro, the eight chorus parameters will be automatically ad-
justed to the optimal values. Rather than individually adjusting each chorus parameter, it is
easier to first set the Chorus Macro (listed in the MIDI implementation as p.175), and then
modify only those parameters that you wish to modify. In particular when using MIDI Ex-
clusive messages, this method of making settings will minimize the amount of data.
