Input/Instrument button disappeared in software instrument track (unable to select a software instrument)

This is to validate your issue. I have just had this happen. I have both Logic 10.8 and 11.2. 10.8 I run in Rosetta for the sake of sync'ing to Sibelius. Both versions on a new project work as expected. Both versions on a particular project have this issue. That tells me the problem is with the project and not the program.

To get around it, I have duplicated a software instrument track and then changed it to what I need to add. (Obviously at some point during the project the anomaly occurred) It seems to be the only solution to finishing a project that I don't want to recreate or copy instruments and audio over to a new project.

After the update, I had the same issue. Reinstalling fixed it.

Sir,

please update to the latest version Logic Pro paying mind to backing up your current version of Logic Pro first.

11.2.1

Sounds like a corrupt session. I would try to reinstall Logic.

Let's see what other folks say.

Other people have reported this on 11.2 as well:

Make sure to notify Apple right away... this could be extremely valuable. It's the most effective method to catch the attention of the Logic Pro team.

Submit Feedback to Apple:

Report your issues to Apple. Fixes may not be implemented until they are reported. These forums are user-to-user platforms, and Apple’s involvement is limited to their own schedule. While Apple may not respond directly, the more feedback received, the better understanding they gain of existing issues and potential updates for future versions. Without reporting your concerns, Apple will not be aware of them.

You Guys think you are having issues....Check out my Screen! What happened to the "Track Header" 😳?

This happens when I navigate to another Desktop/Window for sometime. Everything goes back to normal once I click on it, but it's weird for sure. Have a Great Day!
