For amusement purposes only… after importing a MIDI file as keyframes (see earlier post), I rendered it back out using After Effects as a synthesizer, with the provided Tone audio effect.
This was done by setting the Tone frequency expressions to reconstruct the appropriate musical pitch:
on = effect("ch_1_vel")("Slider").value ? 1 : 0;
note = effect("ch_1_pitch")("Slider");
on * 440 * Math.pow(2, (note-57)/12)
You could change 12 to something else, to hear it performed in some alternate equal-tempered scale. 8 and 17 sound kind-of interesting…
And here’s the self-contained CS5 project to download.
Hi, I was wondering if there’s a way of processing an Image (in a layer) in after effects.
reading pixel by pixel color value. can u’r python script provide answer? thanks
