Auto-assigning a sample but keeping the tempo, possible?

I'm trying to make a drum n bass track, so I sampled some wobbles off of massive on my computer and tried using the chromatic auto assign tool on JJos1 but my samples fall completely out of sync on the different notes, obviously. Is there a way I can do this but make it conserve the tempo, or another way around it? Perhaps I should just try recording it differently? (using FL studio)
Thanks,
Austin

im not entirely sure if i understand you right but possibly chop it up and make it a patch phrase. this should allow it to conform to whatever tempo ur working with

You should do an instrument multisample if you have LFOs/filters/whatnot synced to a specific tempo and time-signature. Then they'll be in time and sync for the keys you need them to be.

Eg. Sample keys E,F,G and create inst program and assign these to the same keys (+ one semitone up and down should work still) in the program and bang away.

Oh btw. I don't know if jjos1 has inst pgm & key-ranges. U should get os2 or os2xl
