TRACKING VOLUME HELP FOR S/PDIF AND 1/4 CABLES

YO, I HAVE A COUPLES QUESTIONS ABOUT TRACKING...

NOW, WHEN TRACKING.. I USE SPDIF WITH THE MPC & 1/4 WITH THE KEYBOARD...

NOW, I'VE BEEN TOLD THAT I CANNOT ADJUST THE VOLUME OF THE S/PDIF WITH MY MPC (OR MBOX2?) WHILE TRACKING..

BUT I CAN ADJUST INPUTS 1 & 2 ON THE MBOX2, WHILE TRACKING THE KEYBOARD..

NOW, WHEN I TRACK, THE VOLUME OF THE S/PDIF TRACK IS KIND OF LOW, (NOT AS HOT AS POSSIBLE) BUT I CAN ADJUST IT WHEN I MIX THE TRACK DOWN....

BUT WHEN I GO TO TRACK DOWN MY KEYBOARD, HOW SHOULD THE VOLUME LEVEL BE ADJUSTED??

IMENA, SHOULD I ADJUST THE VOLUME KNOB (ON THE KEYBOARD) TO AS HOT AS POSSIBLE WITHOUT CLIPPING?

IN THE MIDDLE?

OR JUST THE INPUT KNOBS ON PRO TOOLS TO AS HOT AS POSSIBLE?

THIS CONFUSES ME...





MY SECOND QUESTION IS.. HOW MANY TRACKS AM I ALLOWED TO RECORD ON PRO TOOLS??

CUZ WHEN I TRIED TO RECORD LIKE 26 TRACKS, I GOT A MESSAGE SAYING "THERE ARE MORE AUDIO TRACKS THAN AVAILIBLE VOICES. AS A RESULT, ONE ORE MORE AUDIO TRACKS WILL NOT PLAY."

AND "DYN" WAS HIGHLIGHTED BLUE ON THE TRACK...

SORRY FOR ANY INCONVIENCE, MY METHOD ONE DVD WILL NOT PLAY ANYMORE FOR SOME REASON...

ANYONE??

THANKS FOR EVERYONES HELP... FIGURED OUT THAT I NEEDED TO SET MASTER LEVEL ON MPC TO -6DB

THAT CONTROLS THE S/PDIF GAIN/VOLUME....
