[jmsl] Exporting to Midi

[jmsl at music.columbia.edu]

try this (untested!)
After you turn on midi logging...

        oldClock = JMSL.clock;
        JMSL.clock = new NonRealTimeMusicClock();
        double launchTime = JMSL.now();
        noteLurker.setLaunchTime(launchTime);
        col.launch(launchTime);

// add a Playable to col's stopplayables, so that you are notified when 
the col finishes, when that Playable is notifies, do this:
JMSL.clock = oldClock;
