|
Any time the bus is "touched", ie. has its value set (using "/c_set"
|
||
|
|
etc.), a single impulse trigger will be generated. Its amplitude is the
|
||
|
|
value that the bus was set to.
|
||
|
|
|
||
|
|
If the bus is set link::Classes/Bus#Synchronous Control Bus Methods#synchronously:: no trigger will be generated.
