The demo pieces of a Napo app are not audio recordings but commands to the app to select stops and to play notes. So this is a live performance in which you see the stop buttons move in the Console view and also can watch the used keys in the screen keyboards. Furthermore, you can select stops yourself while the demo is playing or even use a MIDI keyboard to play along with the demo.
The Demo view shows a list of the included demo pieces, grouped by their polyphony requirements. Let us use PiteaMini as an example:
When you tap an entry and decided whether the selection of the stops should be done automatically or manually, the demo starts and the app switches to the Console view, where you can either watch the automatic registration or select the stops yourself. A Stop Demo button appears at the Console view for letting you stop the demo. If you would like to, you can also record the demo music (of course you will first start the recorder and then the demo piece).
In Napo 4.11, the Stop Demo offers to stop the demo or to pause it. In the latter case the demo can be continued by tapping the button again.
By tapping the question mark adjacent to the name of a demo piece you get more information about the piece:
You return to the list by tapping Done.
