Add the ability to have multiple "Listen Buses" to use for mutliple monitoring systems/ headphone setups.
One Listen Bus on the Main Out set to have something like Sonarworks correction software for the monitors, and another for the headphones output (yet still coming from the Main Out).
"Another" popular software has the ability to have such vst plugins on different outputs so no matter what output the sound is coming from, the correction software is already setup right for the user.
I can do this now (version 4) with the Pipeline VST plugin and any other number of outputs. Unfortunately this seems a better solution than the new Listen Bus's current implementation to properly mimic such a useage.
