Logic Pro X will not delete any of my control surfaces.

First, make sure you unplug all external hardware controllers. Also, power down (and not just put to sleep) your iPad if you have used any app in the past to remote control Logic Pro... or you have already installed and used the new Logic Pro X remote control App.

Now start Logic and delete control surfaces.

Quit Logic. (Not just close Logic.. but quit it)

Restart Logic and go back and delete CS's again if there are any still present.

Quit Logic and restart once more...

Check CS surfaces to make sure they are all gone.

If they are then... (and if not, repeat the previous few steps until they have all gone. It can take a few attempts I have found under certain circumstances..)

Quit Logic and then connect any hardware, one at a time and start Logic. to set them up.

However, If you are trying to use the iPad remote control app.. don't connect any external Midi controller hardware to begin with but instead start Logic Pro X and then start the LPX remote control app on your iPad and get it connected following the instructions on the iPad.

Once the LPX Remote Control app is working.... and please test before doing anything else... Then and only then reconnect any external Midi controllers... and set them up.

Dear 'ArtofSound,' -- Thanks for your posts! One of your suggestions solved my problem, I found and deleted the preference file you suggested, .. com.apple.logic.pro.cs.

The next time I open Logic my simple iControl (controller surface) was there, all by itself, and recognized. Gads knows what was wrong but the error message was like 'The Midi port doesn't exists,'

And efforts to fix it resulted in more and more iControl icons appears, all also not working. It started to feel like Mickey Mouse in the Sorcerer's Apprentice.

Thanks again!

Andy,

In that case... simply unplug and turn off every form of external CS device... including iPads and iPhones.. (Not sleep but power down!)

Quit Logic and then delete Logic's CS preference file... com.apple.logic.pro.cs

....which is found in the User Library

<system drive>/Users/<User name>/Library/Preferences (Note: this is the User Library and not the System Library!)

Leaving all Midi controllers, iPads/iPhones and any other possible CS's unplugged and turned off.. Now restart Logic Pro X and the CS file will be rebuilt.

Now check your CS prefs in LPX to ensure they are all gone. If not follow my instructions in my first post here but typically they will be gone unless you haven't unplugged and turned off all your possible CS's...

It appears that I do not have the preference file in my library. I have performed a spotlight search of it and no results are shown. I still cannot delete the control surfaces even with all of my devices unplugged and turned off. Any suggestions?

You should have the prefs file on your system. You are probably looking in the wrong library... Check your path is exactly as shown with the items inside < and> replaced with your Hard drive's name and your User name..

<system drive>/Users/<User name>/Library/Preferences (Note: this is the User Library and not the System Library!)

If you cannot find it manually... in finder.. hold down the option key and left click on GO in the menu bar.. and select Library from there.. That will then show your User Library in finder.. then navigate to the Preferences folder and look for the file named com.apple.logic.pro.cs

...and no, spotlight will not show it unless you tell spotlight to show system files..

Hi Ajesh. I am having the exact same issue--I delete nanokontrol2 from Control Surfaces, which I need to do in order for it to work, and every time I reopen Logic, it reappears. Very annoying. Did you ever find a solution?

Confirmed here.

Thanks for the reply. Unfortunately, my Surfaces just will not delete.

Thanks, deleting the Prefs file did the trick!

Andy,

Great!

Glad to hear it and thanks for letting us know what worked for you...

As always, such feedback is much apprectaed...

Cheers!

Thank you. the file was hidden. I appreciate it.

You are welcome 60....

Cheers..

Nigel

I deleted the CS file in preferences, and I connect my Korg Kontrol and open Logic X.
And its there again. And I'm trying to delete it, and it doesn't get deleted.
This has been a real pain. 😟

It just doesn't delete my MIDI controller. The option comes when I right click it, but when I click on it nothing happens. Seems very strange.
