Load Instrument track with Bluecat Patchwork synth(this is version 2.41 as latest)
Go to console, show Instruments column
Click on row to fold down outputs
All listed as they should total 8
Main is checked and shown
Outputs Aux 1 to Aux 7 checkboxes are shown but no channels are added if checked.
Neither is anything shown in Inspector if you fold down to associate an output - just the default main.
All boxes checked.
In Cubase Pro 9.5.40 this works just fine with VST3 version.
I also have Patchwork v1.x where I stayed on VST2 version installed and that works too,
It's just something missing in StudioOne 4.5.5 to activate outs in VST3, and earlier too, bought 4.1 a year ago.
It's Windows 7 Pro x64 everything.
Also got confirmation from niles here, works in Bitwig as well and not StudioOne
Would be good if fixed, thanks.
