(solved)Z3TA+ inconsistent behavior on sonar pro

So i just bought sonar, and granted I'm a newbie, so far i have had a not great time finding the exact info I want on something, and many docs are sonarx2(old), so... But beyond that, i love z3ta+, but it has inconsistent behavior in my tests, for instance, sometimes I'm holding a key(this is all piano roll based), and then there is a switch to another key, but the sound doesnt always play, sometimes it plays the other key, sometimes it doesnt, its crazy because i don't even know whats wrong, it just chooses when to work, when to play the entire track, with all the keys, and when to only play select keys... o.O

Any help/assistance would be nice. :)
