Master/slave file names appended
A PDF needs to have the exact file name on the slave for it to be found. But this is a problem with transposing instruments and naming the different files (or a corresponding lyric file) as a set, one for each iPad (musician) because each file has to have the same name.
What would be good is to be able to have a (perhaps) period as separator then any alphanumeric addition before the .PDF.
where x is the usual filename of the PDF.
This means it is easy to prepare each PDF without having to use the same name or re-naming. The slave would search the first part of the file name.
Perhaps an extension of this idea is being able to hide PDFs so if an iPad has alto1 and alto2 PDFs, the appropriate ones are hidden before the session (search 'alto2' to filter, hide) so the correct one is loaded from the Master connection.
Lets say you have a song called mysong.pdf on your iPad but it's a keyboard chart. Now your singer has mysong.pdf on her iPad and it has lyrics. When you pull up your chart and you are the master, your iPad says "dial up mysong.pdf". Now her iPad will go, OK got it and load the version of mysong.pdf with the lyrics on it.

Aron, I'm confused then. How is that accomplished? I can only find an option to send a PDF file from one iPad to another. I don't want to send my PDF keyboard charts to the vocalists. I don't have the lyrics to the songs. They have their own PDF files with lyrics only.
Ed, that's exactly how it works now. It looks for the same name.

An alternative or optional option to this idea- Rather than sending a PDF from the Master to the Slave, have the Master simply send a command to display the same named PDF on the Slave's iPad. This way, each iPad user can have their own charts or lyrics or whatever they use. The 'Slaved' user is then responsible for their own PDF documents.
I had already thought of this a while ago and actually implemented some of it. Will work on it some more.
