Hi Rudy,
Can I check what you mean by page? I'm assuming you mean you are using PDF songs sheets with multiple pages rather than OpenSong songs? The comments below are on this assumption.
The on screen scroll down arrow can still be used. You now have 2 options for this. You can set up a page button to act as this, or you can set up a hot zone to trigger the scroll down. Both of these can be set up from the Controls page. You can also use a foot pedal to do the same.
You can also decide how much scrolling should take place when it is pressed. This setting is found on the Foot pedal controls page. You set it as a percentage of the screen height.
When autoscaling a PDF in portrait mode, it will do the following:
Full scale: each page is drawn so it can be fully seen and will be stretched as wide and tall as possible to allow this to happen. Any extra space at the bottom will show part of the next page.
Width only; the pages will be stretched to fit the width of the screen. The height will be stretched by the same amount required and may run beyond the screen height.
If you are running in portrait orientation on your device, the two scale modes will likely look the same. You'll see the difference if you rotate your device into landscape. You can also set the scroll mode to horizontal for landscape viewing of PDFs when you use full scale mode (This option is in Display > Song settings). Pages will appear as columns that extend to (or beyond) the right of the screen
Performance mode treats songs as a single scrollable entity. V5 didn't allow this for PDFs and this caused problems with auto scroll as each page was treated as a different song. In theory having multiple pages saved as separate songs would revert to this behaviour. Alternatively you could switch to stage mode and it would then treat each page as a separate section and using a next control (rather than scroll down) will show each page in turn. For stage Mode, you can specify the maximum section height to use for each section (last option on the Display>Scaling page).
I will have a think about giving an option to make the scroll button move to the next full page of PDF in performance mode when set to full scale for the next release. However, I've quite a few new features being coded in development just now, so I can't guarantee that this will be on place by next weekend.
Does this help?
