I can't hear anything midi, it apparently records as I see the notes in the arrange window
when using the keyboard for entry and I see the track sound meter blipping up and down.
its hard to say. select the track you are playing back and look at the parameters at left and check the port and channel to see if they agree with the keyboard. you might also try making a virtual instrument track and moving the midi to that track to see if sounds. another thing you can do is open the midi in the event list editor - and check the midi channel. this gets me sometimes - it seems logic will allow you to record various midi channels on a track despite what the midi track is set to.
if all else fails go through the set up wizzard again.
