Watchpoints

A watchpoint is an action you can attach to a patch cord.

A monitor watchpoint is orange. It lets you monitor messages being sent through a patch cord.

A print watchpoint is blue. It lets you monitor messages being sent through a patch cord, but also displays the messages in the Max Console.

A break watchpoint is red. It suspends execution of your patch and opens the debug window. A watchpoint can, if desired, break and monitor at the same time. More information on break watchpoints and stepping through patches using the debugger.

The Watchpoints window shows all currently defined watchpoints. To see it, choose Watchpoints from the Debug menu.

Note: Watchpoints are automatically saved when you quit Max. By default, all Max patches open with debug mode disabled. When debug mode is off, watchpoints are greyed out in an unlocked patcher and hidden in a locked patcher.

About the Watchpoints window:

The left column lists each current watchpoint, with color indicating its type and status.

The Action column contains a pop-up menu for each watchpoint. You can change the type of watchpoint associated with this number (watch, break, or watch/break) or disable the watchpoint by choosing none.

The Sender column lists the source of the message to the watchpoint.

The Patcher column lists the name of the patcher where the watchpoint is located.

The Value column displays any messages a watchpoint receives.

The Count column displays the number of messages received by a watchpoint since it was inserted or made active.

When the watchpoint mode is set to watch/break, the History column displays the three most recent messages received by a watchpoint

Adding a watchpoint

Select the patchcord or patchcords you want to insert watchpoints on and choose Add Watchpoint – Monitor or Add Watchpoint – Break from the Debug menu. A new numbered watchpoint marker will be added to the patchcord.

Removing a watchpoint

Select the patchcord or patchcords that contain the watchpoints you want to remove and choose Remove Watchpoint from the Debug menu. The watchpoint marker will disappear and its entry in the Watchpoint window will be removed (note that the watchpoints are not renumbered. If you add a new watchpoint, the number will be reused).

You can remove all the watchpoints in the active patcher by choosing Remove All Watchpoints from the Debug menu.

Disabling a watchpoint

Select the patch cord that contains the watchpoints you want to disable and choose Disable Watchpoint from the Debug menu. The watchpoint marker on the patch cord will turn gray to indicate it is disabled.
