Hi,
Did you guys noticed any of this?
UltraChannel on a Stereo Bus. Female Vox Preset. The more I send to it the lower the volume. Placed the studio one mixtool on it, inverted the channels, comes back to life.
Turned on and off each element of the UltraChannel and discovered that the only one that does it is the EQ.
Presonus Studio One V2.6
Mac 10.10.5
