Using System Effects
To change the chorus type using MIDI messages, transmit the following System Ex-
clusive Message.
fig.8-1fe
Address: 40 01 38 (CHORUS MACRO)
Data: 00–07
00 = Chorus1, 01 = Chorus 2, 02 = Chorus 3, 03 = Chorus 4, 04 = Feed-
back Chorus, 05 = Flanger, 06 = Short Delay, 07 = Short Delay (FB)
Checksum: Refer to How to calculate the checksum (p.245).
<Example> Setting the chorus type to Chorus4
Transmit the following System Exclusive Message.

About Chorus Type
When you change the Chorus Type, 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 Type (listed in the MIDI implementation as CHORUS MACRO
p.236), and then modify only those parameters that you wish to modify. In particular when
using MIDI Exclusive messages, this method of making settings will minimize the amount
of data.
