Featured Examples

Using a MIDI Control Surface to Interact with a Simulink Model

Use a MIDI control surface as a physical user interface to a Simulink® model, allowing you to use knobs, sliders and buttons to interact with that model. It can be used in Simulink as well as with generated code running on a workstation.
