What is the function of the signal flow in the 'FX Chain' feature?

The 'FX Chain' feature is primarily designed to allow for multiple signal routing configurations, enabling users to create complex and flexible setups for processing audio. This functionality is crucial in professional audio environments, where different effects can be applied in various sequences and paths to achieve a desired sound.

By providing the option to configure the signal flow in multiple ways, users can layer effects, split signals, and incorporate parallel processing, which enhances creative possibilities. This versatility makes it easier to tailor processing chains to specific audio needs, accommodating a wide range of musical styles and production requirements.

In contrast, while simplifying audio playback, restricting effects, or enabling stereo output might be relevant in other contexts, they do not fundamentally capture the primary purpose of the 'FX Chain' feature, which is rooted in advanced routing capabilities.
