this nodes mixes 4 incoming signal into 1. it also allows to define the mix value for each incoming signal.
SET_VALUE
- MIX_I8_F32
/*
* this example demonstrates how to mix 4 signals into a single signal. the `set_mix(channel, value)` method sets the
* mix value where a value of `0.0` means the signal will not be mixed and a value of `1.0` means the signal is fully
* mixed into the output.
*
* note that the output is not averaged i.e if e.g four signals of value `0.7`, `0.6`, `1.0` and `0.9` are mixed, the
* output will be `3.2` and not `0.8`.
*
* the mouse position changes the mix value of the signals.
