Modules by categories

Multi-modules

Modules that contain several “sub-modules”. These can be multiple functions, but also practical “toolboxes” that combine very different tasks in one module. The “Multiple Modules” category is independent of the other, more functionally oriented categories.

Polyphonic modules
