The drum loops you hear in the audio questions are built on the fly from a bank of 46 kicks, 81 snares, 21 claps and 59 hi-hats — all one-shots from Loops de la Crème libraries. Every day the engine picks fresh samples, random tuning, random patterns, so no two rounds ever sound identical.
The percussion loops for Instrument ID are recorded straight from LDLC Kontakt instruments.
