Issues with Keyboard Recording Playback specifically with Sustain Pedal

[BEEMER]

My keyboard records fine in Logic, but sometimes when I play it back the sustain pedal is not on and the notes are all. When I record my vocals the sustain pedal goes away as well. How can i fix this?

The notes are all ... what?

Try this:

1. Open a project that has this issue.
2. Save a copy of the project.
3. In that copy, remove all tracks but one that shows this issue.
4. Replace the instrument with a Logic electric piano instrument.
5. Attach that project here. 
6. Tell us how we should proceed in order to reproduce your issue?

Sorry for that weird typo. 

Basically, let's say I record a song while holding the sustain pedal down the whole time on my keyboard while I play 3 notes. Upon playback, those notes are all sustained and play smoothly. However, after a few more plays in Logic, the sustain goes away and I am left with those 3 notes without the sustain. (Sorry for weird terminology, I am new-er to music..). After a few more re-tries the sustain intermittently comes back. This is not a physical hardware problem and purely software (Logic), as I mentioned sometimes the sustain DOES play. 

I will give your suggestion a go. Thanks.
