Possibly.

Sometimes the synth itself allows tuning the patch used, so find the patch settings and tune it the desired amount.

If they are audio tracks pitch shifting each track is simple, so maybe render the tracks to audio first, then tune the audio ...

Usually there is some way to get it done, just a matter of figuring it out.
Quickest may be to render the track to audio then tune the audio track so you don't have to mess with the synth. Depends on your workflow. If you are happy with the track other than tuning, the conversion from MIDI to audio would be a good option.
