Trig probability randomizes whether a step fires, re-evaluated every cycle

The PROB parameter on Trig Page 1 sets the percentage chance that every trig on a track fires each time it is reached. Default is 100% (always fires). The probability outcome is re-evaluated every time the trig is set to play — it is not pre-computed for the whole loop. PROB can itself be parameter-locked, giving individual steps their own independent probability. At 50% a step fires roughly half the time, but there is no guarantee of alternation — it could fire several times in a row. This differs from the A:B deterministic condition: probability is stochastic, A:B is deterministic. A common mistake is using probability expecting strict alternation; use A:B = 1:2 for guaranteed every-other-loop behavior.

Examples

Set a clap on step 9 to PROB=50% for a loose, human-feeling hi-hat accent. Parameter-lock PROB to 25% on step 13 to make a ghost note appear rarely.

Assessment

Distinguish between PROB=50% and trig condition A:B=1:2. In which scenario would each be preferable?
