Creating MIDI Light Shows

[loopdaflar]

Hello,
Is there a way to use MIDI to create if-then statements to create graphics?

i.e. Can I press two MIDI notes which then create an object at certain coordinates and dimensions based on the multitude of MIDI notes are pressed?

It is possible to use control logic to react to midi using the expression modifier. There are several ways to 'draw' dependant on the notes. What did you have in mind?
