Hi MXJ experts
The Max object ‘ctlin’ finds the device just fine in a patcher window. I wonder how I can instantiate a ‘ctlin’-object in Java.
Can anyone throw me an example to get me started?
What’s wrong with just using the max midi objects and feeding the data into mxj? I certainly would.
Given that you’re in the max environment anyway, you may as well play to its strengths.

Just code aesthetics and the beauty of encapsulation. The ‘ctlin’ and ‘ctlout’ belongs to the BCF2000 object Im writing.
With respect, it sounds like anti-encapsulation!
The point of encapsulation is to partition off units of singular functionality in order to promote re-use. Bundling midi i/o together with code for interpreting the resulting data doesn’t achieve this. I’d still concentrate on getting the BCF specifics working.
Anyway – AFAIK, Java MIDI support on OS X (if that’s what you’re on) has long been flaky, as Apple didn’t see fit to actually make working service provider classes.
Apparently http://www.humatic.de/htools/mmj.htm works quite well, YMMV.

Thanks Owen, I see your point. My idea was to re-use the Max MIDI objects inside the Java object (and they are in a sense already encapsulated). I still think that midi IO should be built into the java object (using Max objects) since a BCF2000 object without midi IO is pointless for any purpose I can think of. Also, I want the object to talk OSC externally and MIDI internally. Anyway, including an external Java library like proMIDI or mmj is not a pretty choice, so in case I can’t instantiate and use the Max midi objects inside Java, I will go for your first proposal and encapsulate the mxj object together with the midi objects in a sub-patcher.
And thank you for the heads-up on mmj, I’ve been looking for something like that for a while.
