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 synchronously no trigger will be generated.
| bus |
The index of the bus to read in from. |
| numChannels |
The number of channels (i.e. adjacent buses) to read in. You cannot modulate this number by assigning it to an argument in a SynthDef. |
