OK, so I know if I click edit instrument on the harp, and load a double bass VST, it will assign it to port 2 of channel 1, and then I can select channel 2 for the Double Bass and it activates.
However, by doing it this way, it assigns both instruments to the same mix port on the mixer, so I can no longer change the volume of the harp and double bass independently. When I add a new VST instrument on the right hand side and assign the channel to the Double Bass to fix this issue, I am incapable of hearing the Double Bass this way. Why is this? What is actually happening with the add VST section when I load another VST instrument/rack?
I clicked the cog to check where the channel and ports were and tried to assign the double bass to those to get it to sound but it isn’t doing that. I closed Dorico and reopened it as I heard this can sometimes be an issue but that hasn’t fixed it.
