Hi, Is there some email address or phone number I can call on for expert support? I don't mind paying a reasonable fee for immediate individualized help. Does Logic Pro employ paid experts? Or are there any freelance experts out there who can help me solve my problem in a matter of minutes or hours, as opposed to the days, weeks, or months that it may take via the maybe-I'll-get-lucky FORUM process? Call me impatient, but I'm anxious to get back to work on my project that was interrupted back in 2002, when Emagic discontinued support for Windows PC. I described my problem 5 days ago under the title: Logic 7 + MacBook Pro = No Sound. To summarize: My Macbook Pro works just fine with my Axiom 61 MIDI controller and Garage Band, but I hear nothing when I record and play using Logic 7.2. The notes are recorded and pictured visually, but there is no sound on playback. I tried to isolate the problem by using Logic 7's virtual keyboard instead of the MIDI controller. In the Environment, I connected physical input to the virtual keyboard; connected the keyboard to a monitor; connected the monitor to sequencer input. I play the keyboard and get positive feedback from the monitor, but still no sound. According to the Macbook's Audio MIDI Setup (AMS), ports 1 & 2 are set at maximum volume; however, a slider labeled "M" is grayed out and its volume is zero. My guess is that "M" stands for Master Volume, and it seemed like that could be the problem, except for the fact that the same setup works just fine with Garage Band. I'd really like to get back to work on my project, and I don't mind paying for expert help. Is there anyone out there who can make sense of this? Or is there some email address or phone number I can call for Logic Pro > Paid Support?
