I have set up a "preview" bus to control the volume of sample and loop previews (as lots of them are too loud). For some reason certain tracks in my song are outputting to the preview bus in addition to the track's assigned bus ? I have checked all the sends and no sends are set up to the preview bus. The only thing assigned to the preview bus is the "Audio Preview Bus" selection in the Media file (sample files) menu. It also seems the preview bus is tied to the master bus so when I mute the preview mus the master gets muted also.
Anyone know why this may be happening? Is the preview bus somehow a default or a duplicate master bus somehow ? Why does it only happen with certain tracks and not all tracks (i.e. some tracks do not also go through the preview bus) ? Is this a glitch or a setting I have missed ?
