One of the lasting mysteries in sonar midi :   I could swear that I had  projects aligned on bar and beat, and have worked with them for weeks, when suddently I find the midi has been shifted forward or back a number of ticks, enough to make things sound wrong.    If I ever find out why, I'll post.  This is an old problem, specific to Platinum (I think).

This is an old problem, specific to Platinum (I think).

Not Platinum specific. Happened to me in X3e also.

Shot in the dark suggestions:
 
- If you're not already, leave one blank measure at the beginning of each project to allow time for the midi to "sync up".
- Try a different USB port.  (You should be on a USB2 port.  Avoid USB3 if you can).
 
- Random setting that affects timing for some users:

That one blank measure at the start of your projects is a really good practice. Thanks for reminding me.
 
I'm already on a USB2.0 port but you would think USB3.0 would be better for music production............
 
Thanks, JonD

As a rule interfaces work best when connected to the port type for which they were designed. Some USB2 interfaces do not work well on USB3 ports. That said, not all ports are created equal.

 
A fix has been found! Timing Offset" in the "Sync and Caching" page of "Preferences" can be adjusted to offset where the MIDI lands when you record. The value you enter here has to match your Roundtrip Audio Reported Latency, which appears in the same preferences window (Synch and Caching) all the way at the bottom. To convert the value from samples to milliseconds, take whatever sampling rate you're using (44.1 or 48) divide it by 1,000 (result will be 44.1 or 48) and then divide your Audio Reported Latency by that number (44.1 or 48) to get the milliseconds you need. This will all line up and work as long as you have the Use Audio Reported Latency box checked.
