Page Turner Hack for Musicians
With single and double tap with the iRig BlueTurn working it's time to mock a UI to test how it would feel to control a music application.
What's the idea?
The mock UI has the basics: record, play, rewind and erase.
If the buffer is empty, it would make sense to have the button (the down in this case) to lay down the audio, aka record. Once the buffer is filled with audio, the button could behave as a play/pause toggle. Recording wouldn't be permitted until the allowed again, safe guarding the user from accidentally trashing their recording!
The left side up button, if tapped once could rewind the audio playback back to the start. Being on the left, it implies going back to the start, at least for those brought up in left to right language systems like English! Tapping it in quick succession could then erase the buffer.
Because the BlueTurn is essentially a keyboard in disguise, press and hold can not be depended upon. Also to stop the rewind feeling laggy, the rewind occurs immediately, rather than waiting for the double-tap period to expire. Even though this technically is wrong, as it means rewind will always occur before a buffer clear, in use it feels more natural. Also if you're going to delete something anyway you really don't care if you rewound it or not!
Demo time!
Here's the result. A UI that feels responsive and potentially viable for a basic audio looper.
See you next time!
