Definition
Round-robin is a sampling technique that cycles through several recordings of the same drum hit, so repeated strikes on one pad never play the identical sample twice in a row.
Example
Hit a real snare ten times and every stroke sounds subtly different. A round-robin snare patch stores several of those takes and rotates through them automatically. The "machine-gun" effect of one stuck sample disappears, which is most obvious on fast hi-hats and rolls.
Why it matters
Identical repeated samples are one of the clearest giveaways of a programmed drum part. Round-robin breaks that uniformity by adding tiny, natural variation to every repeated hit, which is essential for believable hi-hat patterns, buzz rolls, and fast trap-style figures.
How to play or configure
Load several captures of the same drum and set the instrument's playback mode to round-robin or random. Three to eight variations is plenty. Combine it with velocity layers so each loudness band has its own pool of round-robins. On hardware drum racks, look for a "cycle" or "RR" mode in the pad's sample settings, and test it by hammering one pad to confirm the variations rotate.
