in Cubase SX

[eyes without a face]

how do i resize my samples without them sounding strange? ive got 1 bar loops that im using for a track, but i find that when i copy and paste alot of these loops then the performance of the program slows down

any ideas?

Stick the loop in acid and stretch it out for how long you want it, then export it as a wav and stick it in cubase.
Just a question- Have u got your samples on a separate drive as this can speed up your performance?
