Audiowarp enquiry

Hi,i produce house music,and have just been writing my own material,never used audiowarp b4.
I have recieved some stems for a remix and there was a arpeggiated riff that wasnt at same tempo as i wanted.The way i sortedthis was in audiowarp,then freewarp, and just moved bits about until it was in time.
Is this the correct way of doin this,or is there a simpler way of going about it?

Make sure the correct original tempo is entered in the Pool and put the track in Musical Mode.

thanks for reply,i dont know the original tempo.

There’s a Tempo Definition tool and a Tap function, or is the clip too short?
