Multiple Keyboards (Two-Hand Mode in Landscape)

[liplum]

Proposal

Users might play the ensemble with both hands.
This fits perfectly with landscape mode.

Basic Support

• Replace the Sheet Screen with another Keyboard.
• Allow users to choose different Soundpack for each keyboard.

Advanced Support

• Multiple keyboards if the screen has enough room, e.g., using tablet.

If the multiple keyboard is allowed, all systems about keyboard and sheet will be affected.
This issue should be taken into account as soon as possible during early prototyping.

What will be affected:

1. Some keyboards will work as BGM, it shouldn't stop as soon as tapping up. So these states should be saved for each keyboards. Stop the sound when tap up #4
2. Vibration will be verbose if too many keys are being pressed. It should work on only one keyboard, main keyboard?, or completely disabled. Interactive Feedback #2
3. Sheet music system is required to support multi-soundtrack with multiple keyboard. Sheet Music #14
4. One device can only recognize one keyboard physical as input. Two-Hand Mode will not reject physical keyboard and allow one keyboard to be bound with one of keyboards. Physical Keyboard Support #16

Two-Hand Mode will be disabled if the screen is too small. So, it might not support split screen feature. But what if a large screen? Split screen should consider the window size of app, not the real screen size. #6
