Pure Music volume control through iPad

.

There is an app called Remote that will do what you want. It controls iTunes volume on the Mini which is linked to the PM volume control.

I use it with an iPad and Remote and don't notice a delay. There may be a very small one but not like your sitting there waiting for it to react.

I also use it sometimes with Screens which is a VNC program when I want to play with the preferences and that works well too.

If you email them they are very responsive and might have some ideas.
