ofxPatchbay
This is modified version by moebiusSurfing from https://github.com/e7mac/ofxPatchbay.
Removed all input controllers (keys, mouse and MIDI). Added new ``
ofParameter<float>` controller. A simplified API.
Thanks @e7mac!
Example Code:
ofApp.h `.c++ ofxPatchbay patchbay;
// controllers ofParameter<float>pController0{ "pController0", 0, 0, 1 }; ofParameter<float>pController1{ "pController1", 0, 0, 1 }; ofParameter<float>pController2{ "pController2", 0, 0, 1 }; ofParameter<float>pController3{ "pController3", 0, 0, 1 };
// targets ofParameter<float>pTarget0{ "pTarget0", 0, 0, 1 }; ofParameter<float>pTarget1{ "pTarget1", 0, 0, 1 }; ofParameter<float>pTarget2{ "pTarget2", 0, 0, 1 }; ofParameter<float>pTarget3{ "pTarget3", 0, 0, 1 };
ofApp.cpp
.c++ // controllers gControllers.add(pController0); gControllers.add(pController1); gControllers.add(pController2); gControllers.add(pController3);
// targets gTargets.add(pTarget0); gTargets.add(pTarget1); gTargets.add(pTarget2); gTargets.add(pTarget3);
// define controllers patchbay.addController(pController0); patchbay.addController(pController1); patchbay.addController(pController2); patchbay.addController(pController3);
// define targets patchbay.addTarget(pTarget0); patchbay.addTarget(pTarget1); patchbay.addTarget(pTarget2); patchbay.addTarget(pTarget3);
// initialize patchbay.setupParameters();
//-
// disconnect patchbay.disconnectAll();
// connect patchbay.link(0, 3); patchbay.link(1, 1); patchbay.link(2, 2); patchbay.link(3, 0);
---------------------------------
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.
Usage
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");
Installation
Define this object in ofApp.h
ofxPatchbay patchbay; `
And add this line to
Dependencies
Uses ofxMidi for MIDI controller input. Uses BlackHole 16ch as the default Audio input. This can be changed in
