I'm trying to get a midi input from a midi controller (APC20) in processing. Some parts of this midi should be passed through, the other part should be converted to OSC.

Now the problem is that I can't get promidi to work accepting midi messages. Can someone help?

2. import oscP5.*;        // oscP5 library
3. import netP5.*;        // included with oscP5 library
4. import controlP5.*;    // GUI library
5. import promidi.*;

7. OscP5 oscP5;                               // oscP5 object                      
8. NetAddress ResolumeOSC;                   // IP      
9. OscMessage myMessage = new OscMessage(""); // message object 
10. ControlP5 controlP5;                       // gui object
11. MidiIO midiIO;
12. MultiList uimidilist;
13. public String actiefMidi;
14. public int actiefMidiNummer;
15.

20.   size(520,150);
21.   frameRate(25);
22.   
23.   //OSC DEEL
24.   ResolumeOSC = new NetAddress("127.0.0.1", 6666);   //start OSC
25.   oscP5 = new OscP5(this,10000); //listening OSC
26.   
27.   // UI DEEL sliders -> (name, min, max, initial, x, y, width, height)
28.   controlP5 = new ControlP5(this);
29.   controlP5.addSlider("sFade",0,1,1,20,20,15,100).setId(1);   
30.   controlP5.addButton("clear",0,60,100,90,20);
31. 
    
32.   //UI met MIDI
33.   midiIO = MidiIO.getInstance(this);
34.   uimidilist = controlP5.addMultiList("MidiInputLijst",0,10,150,12); // multilist to controlP5
35.   MultiListButton b; //add multiListButton to use for adding buttons to multilist
36.   
37.   b = uimidilist.add("MidiIn",1);
38.   for(int i = 0; i < midiIO.numberOfInputDevices();i++){
39.     MultiListButton c = b.add(nf(i,2)+": "+midiIO.getInputDeviceName(i),i);

41.   }

78.   actiefMidi = midiIO.getInputDeviceName(input); 
79.   actiefMidiNummer= input;
80. }
81. 
    
82. //void controlEvent(ControlEvent theEvent) { //DROPDOWN MENU
83. //  println(theEvent.controller().name()+" = "+theEvent.value());  
84.   // uncomment the line below to remove a multilist item when clicked.
85.   // theEvent.controller().remove();
86. //}
87. 
    
88. // each slider calls its own event function:
89. public void sFade(float theValue) {
90.   sendMsg("/activelayer/fade",theValue); // FLOAT slider
91. }
92. 
    
93. void clear(){
94.   sendMsg("/activelayer/testtesttest",1); // CLEAR knop
95. }
96. 
    

Sorry but the comments are in Dutch, and there are also some test classes to check if the buttons work. What's the best way to make the midi input from my midi controller to variables? And variables to midi message?

Thanks a lot!
