There is no latency when I'm triggering from my controller but after recording MIDI data and stopping playback, the MIDI data shows up a few milliseconds too early in the Piano Roll view and therefore plays out of time.
 
I would understand if the MIDI notes were 'late' but instead, they're printing out early.
 
What could cause this to happen?

Happens to me too. Apparently this is an issue that doesn't happen to everyone and seems to be connected with the kind of hardware you're using. My audio interface doesn't have a midi input so I use a separate USB MIDI cable. I don't know for sure if this is why this happens, but the way I deal with it is by nudging every midi clip I record to the right, right after I record it -kinda like quantizing but not the midi notes specifically but the entire clip. I use the total round trip latency reported to Sonar by the audio interface. I take that same number (in samples) and enter it into my nudge right 1 settings and then I just nudge right after recording a midi clip and it lines up perfectly. It's pretty painless.

I would do the same thing but for me it's actually a bit of a pain.

How so? Once you enter that number into your nudge settings you don't have to change it again. To nudge right all you have to do is hit one key on your keyboard.

This is always a tough one to diagose due to the chance of human error. An interesting experiment would be to quantise a midi track so that it is perfectly in time, then use loopbe virtual midi to record the output of that track to a new midi track in real time and see if it stays in time. If there was a difference, you would then have a precise amount to nudge by.

Or the OP can just do what I suggested, which has worked for me and several other people, and not have to go through all those steps. This is not human error. There is an issue that some people experience with Sonar, the metronome, and certain hardware configurations. I don't know what the cause is. I just now how to correct the issue after it happens. There doesn't seem to be a solution to prevent it from happening.

I mean the nudging. Nudging every time I record.

Don't know what else to tell you. If you find a better fix, let me know.

After going through the thread, I've come to the conclusion that it's probably just my audio interface. I mean, I've had much better performance from the same audio interface on a Mac but anyway... I guess I'll be looking to try SONAR on Mac and hoping that many, if not all of my current woes vanish away.
 
Thanks, guys!
