Multitouch Piano Keyboard

[Batninja]

Hi all.

I want to develop a piano-style keyboard for IOS.

Multitouch using Touchstart/Touchend works fine for the individual Round Rectangle Graphic keys but I'd like to include the ability to drag a finger across the keys to trigger notes as well (rather than just tapping them).

Does anyone have any suggestions for a good approach?

Many thanks as usual for all and any comments or suggestions.

Roger.

Look at touchMove in the built-in Dictionary.

If I were developing that sort of thing on a desktop I'd start playing around with mouseMove.
