RandomFX Lab adds "accidents" to your beat that sound planned. On every step of the grid (from 1/4 to 1/32, triplets included) the plug-in rolls the dice on a short event: a stutter, a reverse, a filter sweep, a bitcrush, a tape stop, a delay throw or an octave drop. Probability sets how often something happens, and Chaos how long and how strong the events are. The randomness is repeatable: the result depends on the Seed and the position in the song, so every time you play the same bar exactly the same thing happens — nothing gets lost on export. Roll picks a new pattern, Lock loops a two-bar pattern, and Hold freezes the current effect for as long as you hold it. FX Type selects all effects, a ready-made pool (Glitch, DJ, Lo-Fi) or a single effect. The display shows a step lane with the scheduled events and a waveform coloured by effect, and the module row below it shows which effect is playing right now. Events fade in and out with short crossfades, so nothing clicks.
