I installed the "Java for Mac OS X 10.5 Update 6" update today and promidi immediately stopped working.

Anyone know of a solution?

Specifically I wonder if the new version of mmj, mmj64, might fix this.

This requires registration and purchase, though the price is cheap (E3.5).

If there's any evidence that it might work, I'll buy it.

I have the same problem. Installed the update and MIDI is broken. I guess we have to wait for a new MMJ release...

Is there any way to fix this? I need to have this project done next week.

Not to ask a dumb question, but have you made sure that the mmj files have gotten copied over *after* the installation? It may simply have overwritten their spot in Library.

Anyway, the real point here is that we need an open source replacement for mmj, period. You can't rely on Apple because they dropped MIDI support long ago. And having a tool that simple that requires a license is just absurd... particularly given the fact that most people using Java at this point for music are doing open source development with it, and thus aren't interested in proprietary solutions (or, conversely, there's barely anyone out there to pay a license fee).

Yes that was my first idea too, and, no, that wasn't the problem. After installing the new mmj (aka mmj64) the problem with promidi remains.

Agreed about the need for an open source, or at least, license free solution.

Thanks, ronze, for the reversion link. I will probably undo the update too.

Weird. Just no idea what would break that in the new Java, given that there *isn't* an implementation there in the first place. Disturbing, if Apple has in fact found a way to permanently break MIDI...

hi all,

trying to solve my midi problems on mac i  had wrapped the 3 main midi libraries available for processing (promidi, rwmidi and themidibus) so that i could try them all and fix the problem somehow. with no luck..

As you mention this java update now include a midi implementation, i tried removing all the midi implementation that we had to have on mac before this update. (mmj or mandolib)
surprise surprise !!
both rwMidi and themidibus worked like a charm !!
they display my midi controller with a new name compared to what i use to have before midi started to fail. but it works

thanks a lot for pointing out !

i am now wondering why is it needed to update themidibus ?

i hope it works for you too !

edit: i updated to the lastest version of theMidibus, and while doing so, my app now blocks when i call themidibus function. i checked the working version i have , its class files were compiled on the 18th of march 2009 at 2AM. if any one wants this version of the jar, send me a message : motscousus at google mail
so i am left with rwmidi that works...

Hey all,

So it's seems to be something very silly, only input devices can't be close, outputs can. Meh whatever.

Either way, it should be fixed now. You can get all the details on the MidiBus webpage.

You will have to uninstall mmj as mots mentioned. It says how to do so on the MidiBus page if you're not sure. Then install the latest midibus

Just for future reference anyone running 10.4 or earlier (like my PPC laptop!) obviously needs to leave MMJ installed because this java update doesn't apply to you meaning you are unaffected by this topic.

Please e-mail me if you're still having issues as I only had minimal time to work on this.
