27. Combiners

Most synthesis systems provide a means to combine, or mix together, several or even many signal sources. While there is not a generally agreed upon name, modules of this sort are often known as combiners, or mixers. Combiners frequently have a means for the user to control the relative levels of the assorted signals that will be combined.

Example 27-1: A combiner (mixer) will accept multiple signals and combine them into one output signal.

The output of an oscillator can also be combined with the output of a digital recording.

Example 27-2: A combiner (mixer) will accept multiple signals and combine them into one output signal.

There is no rule defining how many signal sources a combiner will accept. Some systems permit only two or three, while others have combiner modules that can handle a virtually unlimited number of inputs.
