Akai Force realtime Warp Algorithm introduces Glitches and Ghost Notes on drum and percussive content when your Project BPM is more than 4-5 % lower than the loop.
The Best Option Sound Quality Wise is to Slice the Loop like REX loops.
However Sample Edit: Time Stretch can also be used as in this video for better sounding results than the WARP (which works find for melodic content)
This is a quick video using handheld mobile, so bear with the quality.
