Instruments greyed out on project
Currently working on a project that has 1 Cakewalk TTS-1, 1 Cakewalk Soundcenter and 2 of the same 3rd party VST loaded onto instrument tracks. I would now like to load up another track of the 3rd party VST but all of my soft synths are now greyed out, including the Cakewalk ones. It seems to be just this project - if I open another they are available for use.
Any ideas guys?
