Which feature allows for simultaneous adjustments across multiple engines in the S6000?

The feature that allows for simultaneous adjustments across multiple engines in the S6000 is found within the Frame > E 1-4 menu. This option enables users to adjust parameters for a selected range of engines simultaneously, enhancing workflow efficiency. When multiple engines are selected, adjustments made in this section apply to all selected engines at once, which is invaluable for making cohesive changes in a multi-engine setup like the S6000.

This capability significantly streamlines the process of managing audio parameters across different engines, making it easier for users to maintain consistent sound quality and settings across their project. The other choices, while they may offer different configuration settings or options, do not provide the same level of simultaneous control over multiple engines.
