Openframeworks addon that allows you to quickly and easily plug various controllers (MIDI controller, audio, mouse, keyboard) to parameters that you can define in your code.
Let's say you want to control the size of a rectangle that you defined somewhere (ofRectangle rect). Register a lambda function with the patchbay, giving it a human-readable name. The closure should accept a parameter value, which will be a float in the range [0,1]
patchbay.registerControllable1f("rect-size", [&] (float value) {
rect.setHeight(100 * value);
rect.setWidth(100 * value);
});
Now you can connect the x-position of the mouse to the registered parameter:
patchbay.connect1f("mouse-x", "rect-size");
You can disconnect them like this:
patchbay.disconnect1f("mouse-x", "rect-size");
And hook it up to a MIDI controller:
patchbay.connect1f("midi-cc-10", "rect-size");
Or even audio:
patchbay.connect1f("audio-rms", "rect-size");
Define this object in ofApp.h
ofxPatchbay patchbay;
And add this line to ofApp::update()
patchbay.update();
Uses ofxMidi for MIDI controller input.
Uses BlackHole 16ch as the default Audio input. This can be changed in ofxAudioInput.h
