HELP proMidi is hurting
Dec 17th, 2009, 12:39pm  
So I have my assignment in Processing due tomorrow, and now when i turn on my processing sketch I get this error message:

Code:
Exception in thread "Animation Thread" java.lang.ClassCastException: com.sun.media.sound.MidiInDeviceProvider$MidiInDeviceInfo
	at de.humatic.mmj.spi.CoreMidiProvider.getDevice(CoreMidiProvider.java:122)
	at javax.sound.midi.MidiSystem.getMidiDevice(MidiSystem.java:200)
	at promidi.MidiIO.getAvailablePorts(MidiIO.java:182)
	at promidi.MidiIO.<init>(MidiIO.java:122)
	at promidi.MidiIO.getInstance(MidiIO.java:143)
	at mandala1.setup(mandala1.java:69)
	at processing.core.PApplet.handleDraw(PApplet.java:1402)
	at processing.core.PApplet.run(PApplet.java:1327)
	at java.lang.Thread.run(Thread.java:613)


The line of code that is highlighted is this:
Code:

  midiIO = MidiIO.getInstance(this);


This morning I installed a firmware update on my computer, could this be the problem? This assignment is due TOMORROW so please let me know if you have any answers. Everything was working perfectly yesterday...

(I ran some sketches from the proMidi library and they give me the same message, its a problem with the computer maybe... any ideas?)

No worries people I solved it in time.

The new Mac OS java update has its own midi for java hardware driver, so i had to uninstall mmj, problem solved.
