If I select an audio track, I can hear and record anything that I play on my keyboard.
I then select a MIDI track, so that I can record the MIDI note data from my keyboard, but this then de-selects the audio track and I can’t hear my keyboard anymore.
It seems I need to have the audio track and MIDI track selected together, but this looks like it is impossible to do.
I guess when you select the track you make it as “solo” and “Record” Track
so you can play and record on it … only on it
Solution.
go to Edit > preferences > intro Editing List > Project & Mixer
remove check box from Enable Record on selected Track
and
remove check box from Enable Solo on selected Track
