MIDI OUT from inbound on/off switches

Hello everyone,
This is my first time posting in this forum. So not entirely sure im posting this in the right category
My question is How can i use a momentary contact switches (its actually going to be 14 laser to photocell switches) to send a MIDI note on and then off value out over MIDI (which will then trigger a video on my laptop-and off value stops the video).
-As far as wiring i can probably use Tom Igoe's schematic from the physical computing book.
(see attached pics)

But my main hurdle is the Basic code for taking in 14 different laser to photoresistor on off switches and translating that to a MIDI note on off msgs to send out via the wired MIDI port.

Any help at all would be greatly appreciated.

    How are you coding the MIDI out? For the closures you will need another chip (or chips) to handle that many inputs.

    This is a duplicate of this thread: http://forums.parallax.com/showthread.php?p=648931.

    VJ, it's best to post a thread only once. That way the discussion will be confined within a single context, and there's less chance of duplicated effort on the part of forum participants.

    Please don't post the same message in more than one forum. It confuses people, results in duplicate replies, and is against the forum rules. It may be better to post a final comment in the thread where you originally posted your message, referring people to a new forum, then start with a partial introduction to your question with a reference to the original thread.

    No, you would have gotten it. I saw your other post after responding to this one.
