Logic Pro X MIDI keyboard wrong note / Midi doing pitch bends randomly in Logic X

It's not transpose either. It works fine on my oldf MAC - so I think it's a Sonoma 14.5 issue.

It's possible you have either a transpose option activated or accidently some wrong notes assigned to you control surface.

Transpose:

• Click into the empty Main Window, make sure no region is selected. Look now in the Region Inspector, Transpose should have no value assigned.

• There is also a Transpose option in the Track Inspector you like to verify, track by track.

Control Surface:

Create a backup first.

Verify and edit manually here:

Logic Pro > Control Surfaces > Controller Assignements

or just reset the Control Surface Settings:

Logic Pro > Control Surfaces > Rebuild Defaults

Because the same issue exists in Pro Tools,

so, it's not a Logic-related issue. Check the driver of your keyboard.

but there is no problem when I use both MIDI keyboards on different devices. :(

What Midi keyboards?

I use a Novation Launch Key and it works well with Logic. I don't think that Sonoma will cause the issue. The OS itself is not something that would change the midi note value. You might want to try a different usb cable. Preferably USB C to printer. No Hubs.

Have you started your mac?

Have you downloaded the Novation Logic Driver? And checked for keyboard firmware update? I just had a second update on mine in over a year a couple of days ago. In either case, you might delete your midi instrument from the Control Surface Setup and reinstall the mid device.

TRANSPOSE!! Can't believe I figured this out (at least for me). I'm using Logic X with an old M-Audio O2 controller. I found the manual online. It said:

Transpose

You can transpose the keyboard to change the key of the music you are playing without changing the key you are playing in.

1. Press “TRANSPOSE” (OCTAVE + and OCTAVE – together).
2. Press the OCTAVE + or - key for every semi tone you want to transpose up or down.

So it's a hardware issue, I needed to adjust the transpose settings on the controller up two semi-tones and voila, all notes and chords displaying in the Logic LCD display correctly.

Do I get a prize?

LP11 can't handle the M3. I get daily error reports. VST plugins crash. Sound from the MIDI keyboard sounds off, GUI in Falcon is broken but displayed correctly in PreSonus. The performance is simply bad and the support doesn't respond to the daily error reports.

I have the same issue. Logic is playing notes a 1/2 step flat. It does the exact same thing if I use musical typing.

It's possible that the M3 has massive kernel problems with the structure of some programs. But they're both Apple products. So why do so many things go wrong and the customers have the problems?
