I must give my sincerest apologies to all of you for what I have written until now; the usual rant of an idiot.
I checked my MBP to see that Jack Pilot was what I was using on it in 10.6.8 with Logic 9.1.8 and to my great surprise discovered that though it was installed, I had never configured it and so I never actually used it,I assume after configuration is when it would show up in AUdio/MIDI set up and it wasn't there,my very bad.
I was working fairly well in Logic 9.1.8 on the MBP[10.6.8] except that the audio kept doing strange things like not working at all, or worse fading slowly away from the 2 backing tracks[Both Pianos] in playback mode while I was practicing the solo part, the harder I blew into the Akai breath controller the less fade out in the piano background.
How could increasing the cc2 and cc11 coming from the breath controller affect the volume of the other tracks? each track is assigned to its' own channel.
All still in MIDI for now while I practice so that I can correct the wrong notes that appear in the MIDI files when Logic is shut down, the settings all change too,no overlap goes to overlap and all quantize values change and interpretation turns its' self on.
I bought this Mini in oct. 2012, and it came with ML installed, otherwise I would never move up to a new OSX until the 5th or 6th version when the worst bugs might have been fixed. I have never gotten the audio to work as expected,unless complete randomness is now the norm for audio, is it?
Thank you Art of Sound for pointing out the worst of my idiotic rant,I read it now and think-what the heck was I doing when I wrote that. Obviously not thinking very competently.
maybe I was thinking of a WoodyAllen quote; "If you're not failing every now and again, it's a sign that you're not doing anything very inovative." I may be the exception.
