Morphology

modulator = modulate (transparent) = modulate + or

Formed by the verb 'modulate' plus the agent/instrument suffix '-or'; the role of changing or controlling is directly signalled.

Etymology

Modulator comes from the Latin root modus meaning 'measure' or 'manner', the same root as moderate and mode. Think of a modulator as a small control or dial that 'sets' or changes a signal, which is why the word means a device or person that changes or controls signals.
