Reception & Transmission Rules
Only controls that are active in each mode are available
for reception and transmission.
As for functions, when a data entry button below the
display is pressed a corresponding data entry event is
transmitted rather than than the edited value.
•
Reverb and effect type/depth ON events are transmit-
ted simultaneously.
•
Harmony type also transmitted simultaneously with an
ON event.
•
ABC mode transmitted when ABC turned ON, and
ABC is turned ON when an ABC mode message is
received.
For controls such as the DEMO button which is held
while some other operation is performed, an ON event is
transmitted when the button is pressed and an OFF
event is transmitted when the button is released.
OFF ON events are transmitted in succession when an
auto-repeat controller is used.
