| If this piece relies on the input trumpet note being represented as a MIDI note, then you will need a device called a 'pitch to midi converter'.
Max/msp could be used to build a conversion program (or patcher in max/msp parlance)....
Your trumpet would play into a mic (or pickup), which would be plugged into an audio interface for your computer, which would do analog-to-digital conversion. The Max/msp patcher would presumably detect the pitch that you've played, then send out the appropriate MIDI note(s) to whatever you have MIDI'd to the computer (which in this case would probably be another computer running the program that manipulates the video)...
Hope this helps,
