Hi, Hope you are well versed with the PT application. Still let me ask one thing, does the cursor in the edit window blink? Sometimes just a click on the edit window, in a track, makes a tiny selection than a binking pointer. If the Zoom-in level is more, you wont be able to identify it as a selection. If its a selection, the playback or record would happen only for the duration of that selection.To make sure that its not a selection,see if the cursor is blinking. Secondly, when you hit record or play, what's the message appears at the left hand bottom corner of the edit window. Is it,"waiting for MIDI" or "Waiting for Sync" or the like??? Let me know. Happy recording.......!! SS
