aux channels and send automation.

´t work properly

Hey, does anyone have issues when sending group track vols to an aux effect channel?. I have inserted the n-track tempo
delay into the aux channel. The dry vol of the delay is set to inf. and the wet signal to 0.

The issue is that the most I turn up the volume of the aux track, the most sounds down the volume of the gorup track. It
´s like some kind of limiting is being added to the main master.

The most strange thing is that when the aux vol track. is turned up above 0 the clean sound signal fo the group track stop going going down and go up strongly.

Pls could you check it out to know if it is a problem of my configuration or a bug?
