OK, there is another way to do this and this is the way I do it ! -)

Inside the matrix, you put this :

// You need to declare the variable in every macro you use it
Declare Once int $externalActionCount$ = 10

// Here is the macro initialization

// Here is a case branch
CaseBranch "My song two"
	Post "Begin of the second song"

        // inside the casebranch, you can set a global variable that will be used in another macro
	$externalActionCount$ = 5

        // Here you start the second macro which is loaded in a standart macro slot
	MacroStartIfNeededByName "External Action"

        // With WaitSignalNotification, the matrix macro will wait the signal from the other macro saying the action is finished
        // WaitSignalNotification is optional

	WaitSignalNotification ExternalActionIsFinished

	Post "Back to Case Branch 2"

EndCaseBranches

In the external macro called “External Action”, you put this code :

// You need to declare the variable in every macro you use it
Declare Once int $externalActionCount$ = 10
Declare int $currentCount$ = 0

// This macro execute an external action and send a signal when it is finnished.

Post "This macro is doing an external action"

DoRepeat
	$currentCount$ = {$currentCount$ + 1}
	Post {"count " + $currentCount$}

	Sleep 30
While {$currentCount$ < $externalActionCount$}

// When the doRepeat loop is finished, the macro send the notification with NotifySignal
// NotifySignal is optionnal

NotifySignal ExternalActionIsFinished
