Well - maybe something happened to you that happened to me a while ago...
I was using a E-M Xboard61 to record some MIDI tracks. Every time when I recorded something I noticed that after using the pitch wheel the sound was a few semi tones "off center".
It turned out to be a calibration error of the pitch wheel. The calibration was done a bit sloppy leaving a too sensitive "death zone". Even the slightest movement resulted in a pitch bend (most times up, but that varied), and the return to centre was not detected as the zero-centre but slightly off-centre. Even the finest regulators (if you are using non-digital regulators that is) have a slight tolerance, so setting the detection too sensitive is (obviously) not preferable.
This was solved by re-calibration the pitch wheel. It was a three minute affair, and after that the pitch wheel worked as expected.
I do not say this is happening to you, but if the events you describe take place not before, but after using the pitch wheel, the above is maybe a thing to take in consideration
