Layering multiple simultaneous entropy sources yields mush; add one knob of chaos at a time

A generative patch should introduce entropy gradually and audibly, one knob of chaos at a time — a little probabilistic-variation, or a generative-mutation drift, or a polymeter phase, but not all three at once. Layering several independent randomness sources simultaneously produces mush, because their combined variation swamps any recognisable pattern and the listener can no longer track what is being varied. Adding entropy incrementally keeps each source’s contribution legible and keeps the result under control, which matters especially in live performance.

Examples

Good: degradeBy on hats now; add a slow filter drift later; add a polymeter phase later still Bad: degrade + mutate + polymeter all at once → incoherent mush

Assessment

Why does layering probabilistic-variation, generative-mutation, and polymeter simultaneously produce mush, and what is the recommended discipline?
