No Sound From Logic 7 Options

[billrc]

Just put Logic 7 on my new computer and can't get any sound out of it. I hear Garage band. I know it's something really simple but I can't find what it is. Any suggestions? My midi keyboard is making the connection. I see that it is inputting. Can't hear anything from my motu 828 either.

Thanks for any help,
Bill

Thanks for that. Since I'm not using anything but "core audio" right now it dosn't help me. However, since my GarageBand works fine and you can roll over files to Logic I can hear my KB MIDI input that way. There remains the question of why I can't with the Logic Tutorial Song. The Es1-4 voice remains greyed out and contrary to the manual - "Simply selecting the track will arm it for recording"- there is no setting that I can find that makes it possible to listen to MIDI input. Oddly enough, if you go to the Matrix Editor there is no sound from the screen KB but if you manually drag the notes with the mouse you can hear them. Also MIDI input does not register. Also in "Environment" MIDI input shows in window but not in transport and clicking on switch does nothing but advance the total number of MIDI events. Anyway, I have a hell of a lot to learn and thank you and anyone else who can shed some light on what seems to be
"illogical Logic problems".
