Problem using MIDI libraries
Sep 22nd, 2009, 7:17pm  
Hi,


apparently none of the MIDI-libraries work on my macbook (10.4.1). I get the following message when I run Promidi or MIDI bus sketches:

ClassCastException: uk.co.mandolane.midi.mmidi.transmitter$info

Exception in thread "Animation Thread" java.lang.ClassCastException: uk.co.mandolane.midi.MMidiTransmitter$Info
     at de.humatic.mmj.spi.CoreMidiProvider.getDevice(CoreMidiProvider.java:122)
     at javax.sound.midi.MidiSystem.getMidiDevice(MidiSystem.java:200)
     at themidibus.MidiBus.list(MidiBus.java:975)
     at MidiBus_Advanced.setup(MidiBus_Advanced.java:28)
     at processing.core.PApplet.handleDraw(PApplet.java:1400)
     at processing.core.PApplet.run(PApplet.java:1328)
     at java.lang.Thread.run(Thread.java:613)
Any ideas? Thanks for the help!

Please help! I've tried everything:

-re-installing Mandolane (full version, not demo!)
-mmj is in the correct directory
-IAC driver is online

Have I missed something? Also, I tried to install Promidi and MIDIbus in different directories:

Application/Processing/Resources/Java/Libraries

and

Documents/Porcessing/libraries

Still getting the same error message. Getting frustrated, please help!

Thanks, tried that one... I reinstalled Processing and the Examples And Sketches buttons are greyed out. Works fine apart from that, can open files with Cmd+O. How can I get the Examples and Sketches buttons back?

Still, I realized I had Processing 1.0.2 or 3. Where can I get it from? I couldn't find it...
