![]() ![]() Note that timer is a slightly unusual Max object in that its right inlet is hot (produces output), not its left inlet. The timer object is therefore equivalent to a stopwatch click the left-hand button to start the clock, wait a few seconds, and then click the right-hand button to see how much time has elapsed. This object takes bang messages in both inlets the left inlet starts the interval to be timed, and the right inlet stops the interval. The patch labeled 4 demonstrates another object that counts elapsed time: the timer object. Clicking on the stop message will stop the clocker, while sending a new bang message to clocker will restart the timer and the elapsed time measurement. The primary difference between clocker and metro is the output: while the metro object produces bang messages at regular intervals, clocker outputs the overall elapsed time (in milliseconds) since it was started with a bang. Patch 3 shows the clocker object, which is closely related to the metro object. ![]() Both the delay and pipe objects will respond to a stop message to abort pending output. Like pipe, the delay time can be changed by sending an integer value into the right inlet. ![]() This is very similar to the pipe object, except that it is specifically tailored to delay bang messages. The next small patch, labeled 2, is an example of the delay object. Change the right-hand number box to 2000, then change the left input – you will now see the changes occur after a 2 second delay. The delay time can be changed with a value sent to the right inlet – an integer value is used to set the number of milliseconds of delay time. If you change the value of the left number box, you will see your changes reflected in the output 1 second later. The argument provides the default delay time – in this case, 1000 milliseconds (1 second). Patch 1 provides an example of the pipe object, which can be used to delay the passage of any message or list for a certain amount of time. The left-hand side of the tutorial has five small patches that show the operation of a handful of new objects that deal with time in Max. To open the tutorial patch, click on the Open Tutorial button in the upper right-hand corner of the documentation window. These are especially useful when working with time-based objects, since you will often want to make operational decisions based on comparisons between the current time and some desired time or sub-time function. In addition to the time functions, we also cover some of the Boolean comparison objects – objects that create logical results based on comparing and testing input values. All of this is built on the ability to define specific times and time durations in metrically-significant ways. The transport objects in Max provide a centralized musical timing system that can provide play/stop controls, bar/beat feedback and can even cause events to fire at specific points in time. Additionally, we will look at some decision-making objects that use logic operations to determine program flow.Īs we’ve seen in earlier tutorials, the use of time is an important part of working with Max programs time-based objects like metro can help create generative music and drawing actions, and can be used in conjunction with user actions to create playable programs. In this tutorial, we will be working with time – objects that deal with time, and a set of objects that work with a metrical timing system built into Max. ![]()
