I have a midi piano and a camera. My goal is that while I'm playing every time I press a key on the piano a photo is taken for later processing. How can I do that in real time?

Musical Instruments Digital Interface (MIDI) in Audio Toolbox can be used to create, send & receive MIDI messages. So it can be used to set up a piano with MATLAB. And for setting up the webcam using a support package, refer the following link.

For clicking pictures with a keypress, callback functions can be implemented along with a keypress event to simulate this scenario.
