Asanexample,set“q (Tempo)”to100.Noticethat
thepitchdoesnotchangewhenyouplaybackata
differenttempo.
Ifthebeatoftheoriginalrhythmloopsampleisnot
reproducedcorrectlywhenyouchangethetempo,
orifobtrusivenoiseisheard,thisisbecausethe
samplewasnotslicedappropriatelyinstep4.The
wayinwhichthepercussioninstrumentsounds
