This should be fairly easy for some one. I'm new to Metro SE 6.5 I am using a Mac mini. Using a "Presonus Firestudio Project" as my interface. I need to know how to configure Metro so that when I play a midi file It uses the sound set already in the Mac mini. (Assuming its Quicktime). It kind of does it on my MacBook Air without interface. It worked originally when I installed "Metro" then did not work after I quit for the evening. I can't seem to figure it out or find info in the On line manual.
Any help would be appreciated ... Just want to do simple editing of the files.... Thanks in advance for the consideration.
