 Different chips have different capabilities. Even within the same chip, each channel may have its own ways of making sound.
 - Some channels use one or more waveform **generators** (sine, square, noise...) to build up a sound.
 - Of special note are **[FM (frequency modulation)](../4-instrument/fm.md)** channels, which use a number of generators called **operators** that can interact to make very complex sounds.
