Manager available The audio File Player Editors Audio Inputs Input Recorders Instrument Plug ins use its own chain of effects with a built in Insert Effect Manager If you want to apply a series of general effects on the audio output we recommend the use of the Global Effect Manager While in case all you want is to apply only a particular effect and only to the audio coming from a specific generator you can use the Insert Effect Manager of that specific generator Attention effects always need a certain amount of CPU power of your system or of your hardware board devoted to the effects The optimization in the distribution of system resources it is very important with the purpose to avoid useless waste of CPU time during processing For example if two generators use the same effect of reverberation with very similar parameters it can be very much better to use a single reverberation effect on the MasterOut rather than two each in the Insert of generators One of the advantages to using a chain in Insert is that in case of the Audio File Player Editor the Effect Manager can be seen as offline algorithm that can be used also for processing the audio file In fact once set a certain chain of effects in Insert a procedure can be launched of offline rendering treating the chain of the effects as with any other editing algorithm on the audio file Because the processing is carried out offline the amount of time that is spent may be much
