Is there a way to prevent the Doirco Mixer from showing channel strips for all the unused channels?
Not if they’re not contiguous, no, but if you assign them to a contiguous range, you can then specify the number of channels to appear in the Mixer in the Endpoint Setup dialog.
Thanks Daniel, that helps a lot!
Since people using VEP would typically have a Server setup that includes many more instruments than than would be included in any one piece, it would be great if mixer strips were only created for assigned channels.
