I would like to build a virtual mechanical street organ (prop for a small theatre production).
My idea is to use the mouse-wheel and connect it with a crank. The speed rotating the crank should control the speed of a playback of a midi file.
So far so good.
I programmed a routine in vvvv that can measure, how much the value of the mousewheel changend in a given period.
The problem is changing the playback speed of the midi-file. Connecting my result to the speed node of the file-stream node doesn’t work correctly (the playback stopps, if the value is chaning). Any idea?
I found a thread “How do I achieve MIDI file step-by-step playback” but this doesn’t help.
