Note : The runtime effects are run-time features (as their name suggests!) and therefore, they consume CPU. Do not unecessarily apply one or more of these effects if you can apply them as standalone audio effects. For example, do not use the Reverb effect as a real time effect if you can apply it offline in a track.
Note: Runtime effects are applied directly to the DSP output and therefore they cannot take advantage of multicore processors. It is suggested that you use a VST instead, as VSTs can benefit from multicore systems.
Each mixer, each asio port, each link and each track has its own list of runtime audio effects to be applied. You can configure these through the mixer.
When you apply a runtime audio effect to the master out mixer (Master Our or Master Audio Out) the effect can be applied in multiple-channels. That means that if you apply reverb, it will be applied at once to all ASIO outputs (so stereo reverb will work). The same is true for all delay-based effects.
Many of the standard Audio Effects (that is, those that can be applied at run time without significant performance loss) are available as run time effects:
Some other audio effects like Noise Reduction or Pitch Shift require more CPU power and therefore they can't be applied at runtime.
MIDI mixers and links also support a number of MIDI runtime effects:
