Ralph I am so sorry to keep troubling you with this but here's the complete paragraph:
Pushing custom instruments to Air Player
If you want to run instruments in Air Player that are not part of the Sim Innovations library, then these have to be pushed from the Create/Edit tab. Go to the Create/Edit tab, select your Air Player, then select your custom instrument(s) and press Push. To multi select instruments, press SHIFT or CTRL while selecting your instruments.
I know that's exactly what you included in your message, but the part in red above says you can't do anything but push the instrument from the Create/Edit tab which generates a white background. But, I'm hopeful that there's a way around that statement? If there is and I'm not understanding what you are saying to me, this must confirm that I am terribly thick. Please, explain it in different terms so I can stop bothering you!
