Using MIDI to control Frame skipping of video

January 23, 2007 | 7:29 pm

Hi everyone,

Im creating a live drumming project that will involve (i hope) MIDI note on/off messages triggering video on my mac. my ideal is this:

one key, lets say C3, loads a video. each time it is hit, a new video is loaded.

then each time you hit C4, the video skips on one frame per hit.

i am an absolute novice at Max/jitter, and have been trying out the tutorials but cant seem to find anything relevant to my needs.
normally i would try and gain a greater understanding before posting, as i know novices can be annoying and time wasting, but i was wondering if anyone can help me out?

if anyone might be able to explain how i can do this, or at least point me in the right direction, it would be greatly appreciated.

Regards,

Tim

That’s because you need to know enough about message passing
and how Jitter handles playback of a QuickTime movie for anything
we might tell you to make sense.

To be specific, have you read through tutorial 4 in Jitter? It’ll tell
you about how to get information about a movie and how to
control movie playback.

And I’d suggest you look at the Max tutorials on how MIDI is
handled [notein comes immediately to mind here] and enough
of a sense of message passing and an understanding of how
messages and lists work to see how to route such messages
and send them to what you’ll know about QuickTime movies
after you’re done tutorial 4.
