TommyS posted this link some time ago and there's that scale thing where the both C's are exactly the same but still the it seems that the scale rises all the time.
The page says that effect is achieved by mixing same frequencies and the ear automaticly picks the highest one. Does anyone know how those frequencies are mixed? It would be great to have infinitely rising FX patch.
