can't change track in MIDI edit window

also i can edit the bass track but when i click on a note i see the note respond by turning white but i do not hear any sound. this is only in one project, so I'll import into a new project so I can continue, but i was just curious

i have not imported the content to a new project yet. i opened the project and i had a an audio track selected which substituted the audio editing window for the MIDI editor and there was no link or MIDI in and out available as an option. so i clicked in a MIDI track and i had what you show in your animation. 2 clicks solved my problem. really cool animation. very helpful, because my question sounded vague and yet the answer, as you presented it is very clear, very simple and a very quick fix/lesson. 2 thumbs up. i have no idea how much of Logics capabilities i use, it must be a very small percentage and it is so easy to get into trouble. i have one less thing to worry about. thank you very much, thanks for taking the time to show me
