hmm okay.. so you have a drum track set up to use another VSTi and you added guitar etc and at that point thevdrums were no longer in sync with guitars on playback... the drums in question were sequenced outside samplitude? you then triggered that sequence successfully but they didnt stsy in sync... something like that?
if I can better understand the sync issue I might be able to help there. you know what modules, what set up and how you set up triggering etc
so at that point you try using sampitude with kontakt? But now all the sounds orvdrum mix is not the same as the song as you originally recorded it? at that point you are thinking import sounds to kontakt and trigger that from samplitude? or simply to start from scratch using a kontakt kit?
at this point I hope iam close to understanding the prob though i have probably mixed it up. as much detail as possible in terms of what where and when with why as the bonus question
as much details on symptoms and issues will make it easier to diagnose and find a solution or two.
