hi i have just started using cubase le 4 which came with the presonus inspire there are a load of samples on a disc when i put them into cubase is there a way to change the tempo of the sample
Are they audio samples or midi?

If they're midi, just change the tempo of the Cubase project.

If they're audio, you need to use the time stretch tool, and you'll need to know what tempo the samples were originally.
