Controller

The system beahviour is determined by controllers. they are used to:

• Transform messages in real-time
• Control the system.

Controller are applied in response of particular input messages.
In other words, it is possible to do special computations when the user activate an external device (ex: a computer keyboard, a MIDI keyboard...).

A controller is composed by:

• an ID : This unique number is used to identified the controller in script.
• a MASK : it is the condition required to apply the controller
• 2 TCL Scripts: they are both executed when the condition is satisfied. The boths script have different execution modes, on-the fly or in parallel.

The script must be written in TCL.
All funtionalities of TCL 8.3 can be used.
Furthermore, special functions have been added to the language, in order to access the TISM functionalities like sequence managing, control etc.

These special TCL funtions are listed in the Tcl Reference section.
