Output
bang:
Out left outlet: Sent when the input signal changes from zero to non-zero. The minimum time between bang messages will not be shorter than the minimum scheduler interval, which is generally equal to the signal vector size, but may be larger if Scheduler in Audio Interrupt mode is not enabled.
Out right outlet: Sent when the input signal changes from non-zero to zero. The output will not happen more often than the time represented by the number of samples in the current input/output vector size.
