Pulse train generator train~ generates a pulse signal whose period is specifiable in terms of milliseconds (see <~ for a method of making a pulse wave at a specified frequency). It also sends out a bang when going from 0 to 1, so it can be used as a metronome with a floating-point interval. Cycling '74 MSP MSP Synthesis (signal/float) Pulse Interval in ms TEXT_HERE (signal/float) Pulse Width from 0 to 1 TEXT_HERE (signal/float) Phase from 0 to 1 TEXT_HERE (signal) Pulse Output TEXT_HERE bang on 0 to 1 Transition TEXT_HERE Set the inter-pulse interval Sets the initial value for the inter-pulse interval in milliseconds. The default is 1000 ms. If a signal object is connected to this inlet, the corresponding initial argument value is ignored. Set the pulse width Sets the initial value for the pulse width. The default is 0.5. If a signal object is connected to this inlet, the corresponding initial argument value is ignored. Set the pulse phase Sets the initial value for the pulse phase. The default is 0. If a signal object is connected to this inlet, the corresponding initial argument value is ignored. Function depends on inlet Numbers can be used instead of signal objects to control period, pulse width, and phase. If a signal is also connected to the inlet, float and int messages are ignored. Function depends on inlet Numbers can be used instead of signal objects to control period, pulse width, and phase. If a signal is also connected to the inlet, float and int messages are ignored. Function depends on inlet In left inlet: Specifies the period (time interval between pulse cycles), in milliseconds, of a pulse train sent out the left outlet.

In middle inlet: Controls the pulse width or duty cycle. The signal values represent a fraction of the pulse interval that will be devoted to the "on" part of the pulse (signal value of 1). A value of 0 has the smallest "on" pulse size (usually a single sample), while a value of 1 has the largest (usually the entire interval except a single sample). A value of 0.5 makes a pulse with half the time at 1 and half the time at 0.

In right inlet: Sets the phase of the onset of the "on" portion of the pulse. A value of 0 places the "on" portion at the beginning of the interval, while other values (up to 1, which is the same as 0) delay the "on" portion by a fraction of the total inter-pulse interval. The signal output can be used as a control input for sah~ as shown in the example below, or at very small intervals, it is audible. Out left outlet: A pulse (square) wave train having the specified interval, width, and phase. Out right outlet: When the "on" portion of the pulse begins, a bang is sent out the right outlet. Using this outlet, you can use train~ as a signal-synchronized metronome with an interval specifiable as a floating-point (or signal) value. However, there is an unpredictable delay between the "on" portion of the pulse and the actual output of the bang message, which depends in part on the current Max scheduler interval. The delay is guaranteed to be a millisecond or less if the scheduler interval is set to 1 millisecond.
