More MIDI weirdness

Don't know why this happened, but it's easily fixable with volume and/0r velocity adjustments.
Make sure you have put in starting volume events, using CC 7, and then expression events using CC 11. If you're using the Aria player with Garritan sounds, it's also best to put in a CC 1 event for the modwheel. In fact, it may be that that is what is causing the problem, whatever synth you are using. CC 1 controls the modwheel, so if you want to equalize the volume on the three takes, the modwheel would need to be the same. If the tracks were recorded using different synths, the volume and expression controllers would be the ticket. I use a variety of synths, and my keyboard has no modwheel, being ancient like me; but Garritan is the only library where I have to set the modwheel.

You're very welcome. I should elaborate a bit on the use of the CC events 1,7 and 11. 1 usually controls the modwheel on most software synths. Since my keyboard controller has no modwheel, I can adjust that with CC 1. CC 7 is what I use for starting volume. For example, on a software synth like Play or Aria, I may need to use different starting volumes for the flute, clarinet, violins, etc. Even though they're on the same software synth, some instruments may be natively louder than others. CC 7 allows you to normalize those differences. I only use CC 7 once, at the start of the piece. I usually set it at 80 or 100, or close to that. If an inst. is really way too quiet, I set it to 127. If way too loud, maybe 50 or 60. Then, I make "on the fly" adjustements with CC 11, which despite its name (expression) is really a fine-control volume adjustor. Along with velocity, these CC events allow you to have fine control over everything. Also some software synths have individual volume adjustments themselves, like Play (East West). And the synths in the mixer have overall volume levels. so there's all kinds of ways to adjust volume, which makes it confusing, but once you learn it all it all makes sense.
