Step Designer Pattern Playback

When using midi to play back patterns on step designer it sometimes misses the last note of 1/16 pattern. Also if you watch the step designer window while cubase is playing it appears to jump to the next pattern ahead of time before the midi note actaully hits like it has some sort of look ahead.

Does anyone have any tips on using midi to play back patterns to improve performance from what I’m seeing?

Other midi plugins like beat designer dont have this issue.
