Yes. If you are using drum maps and the PRV you are about to discover several bugs. Although most of them also invovleved the step sequencer for me.
Here's a few I've already reported and been confirmed by CW
CWBRN-5782, Minor Step sequencer velocity display issue
CWBRN-5786, Cannot use separate snap to settings in PRV if output is a drum map
CWBRN-5787, Step Sequencer is blank when double clicking on a clip assigned to a drum map
CWBRN-5794, Step sequencer clips truncate on bounce to clip ** has been there since at least V8.3 but I could never pin it down.
