Sorry,
my mistake, I just recognised that both downloadad files were corrupt
I downloadad them again, now both played via "Optimizer7" don´t make any problems.
BTW: I don´t use the built in Audya5 USB-Interface for that, I use a M-Audio MIDISPORT-UNO ( USB to MIDI ) Interface.
BTW: "in my ears" ( via headset ) the guitar on ch.11 in the "criola-fil"e is a little bit too loud, velocity of 80 sounds better for me
