Logic update 10.2.1 Problem: Roland A-49 Keyboard Controller stop working

I have a Roland A-88 controller that stopped working with this Logic Pro X update.

This work around worked perfectly for me. Logic is receiving midi data again from my Roland A-88 .

Hope Apple fixes this problem in there next update.

I have the same problem with my M-Audio Oxygen 49. It works perfectly in MainStage3 and GarageBand, but Logic Pro X does not get any signals from it, with one exception: When the message "Changed number of MIDI inputs/outputs. Now 1 input and 1 output are available" shows after connecting the USB, if I push the message so that it pops up as a new message in the middle of the screen (saying exactly the same), Logic will read whatever I play. But the second I push "OK" on that message, the connection is shut.

Did this, but no help. MIDI Monitor is confirming signals from the Keyboard Controller, but deleting the .device file did not help. What I find is that, I have to "Bypass all control surfaces" in the Logic Pro X > Control Surfaces menu, which is somewhat stupid. Hope there is a update to fix this soon.

I also have had this problem. I have noticed that it happens when I first open Logic Pro X, regardless of the document. If I close that document, and open it again (or any other), my A-49 works again. I will try the workaround.

Try deleting the CS (Control Surface) preference file and then set up your midi device again if needed...

You can resolve many issues by restoring Logic Pro X back to its original settings. This will not impact your media files. To reset your Logic Pro X user preference settings to their original state, do the following:

1. Quit Logic Pro X
2. In the Finder, choose Go to Folder from the Go menu.
3. Type ~/Library/Preferences in the "Go to the folder" field.
4. Press the Go button.
5. Remove the com.apple.logic10.plist file from the Preferences folder. Note that if you have programmed any custom key commands, this will reset them to the defaults. You may wish to export your custom key command as a preset before performing this step. See the Logic Pro X User Manual for details on how to do this.
6. If you are having trouble with a control surface in Logic Pro X, then you may also wish to delete the com.apple.logic.pro.cs file from the preferences folder.
7. Restart the computer.

Note: If you cannot find any of the files listed above, you didn’t follow the instruction correctly! 🙂

this worked a charm, I had exactly the same problem with my roland-A49 and now it works perfectly. thank you!

TY! Tried this once before, but that did not do anything. I restored the files, and deleted them again, and there it was. No bypassing needed.

Logic 10.2.2 has fixed this bug. At least with Roland A-49 !!

Working perfect :-)
