Unlike general send effects, the effects in ADX are multiplied similarly to volume changes.
The sounds are sent from several layers (Cue, Track, Waveform region), the result of multiplying all send values is used as the send value.
The values coming from AISACs or Track Automation are also taken into account and multiplied as well to get the final volume.
Check the following.
The bus sends are applied based on a multiplicative system, and the settings of a Cue, Track, and Waveform are all multiplied together.
In the initial state, the bus sends 1 to 7 of each Track are set to 0.0 (off).
Do not be confused since the bus send is 1.0 (on) when a Cue or Waveform is selected.
By changing this setting, you can send the Track to the effect send.
You need to change the bus send of the Track to which you want to apply the effect to 1.0.
Also, controlling the sounds via a distance attenuation AISAC or a Category will affect the effect. If the value of the bus send is small for each curve point, the effect wil not be applied.
