The Process/Sliding Function

OK, I know how to use the M:B:T (ticks) by just multiplying the beats X the tick resolution, but the seconds, and frames that aren't in whole amts; which hardly EVER happens, aren't so easily managed. So, I had instances of wav file imports where I didn't have them sync'ed up to the beats. But if I can't put decimals in the quantity window for seconds, and frames, honestly, what good is it. I also read that section in the user manual, which doesn't tell you how to use the feature if you have partial amts like 6 sec./19 frames. I mean, do you actually have to use the seconds choice, then turn around and use the frames choice? That would seem AWFULLY silly. Pls Advise, KC
