Yes, you are right Joe, the elegant solution is using Logic Pro X and thank you for mentioning the trial offer, didn’t know that.
But overall and beside the extra cost, I am already more then satisfied with GB. I don’t want to get into even more complex fonctions with the trouble of importing my songs.
I say that because I have found a very good solution to my problem. It’s called MidiPipe an excellent little software that treats midi messages like butter. I only had to filter out cc#007 main volume and voilà.
Its a free software but one should donate and I will certainly do.
so, this is the end of the story, I am so much more relaxed now with my behaved volumes.
Btw, MidiMonitor is only a monitor, it filters messages but only for the sake of monitoring.
Big thanks to all of you, hope this might help other people with similar problems.
Back to my keyboard now!
