PadKontrol LED's patch/mod - like maschine?

[padTomcrol]

I'm not very technical in terms of getting my hands dirty with native mode etc.. just wondered if anyone had made a patch that means the LEDs stay on for the duration of the "press", or light up to indicate a sample is loaded in the host program (battery in my case), or just generally be on unless pressed (for dark gigs). These things have been established in maschine, just wondered how capable PK is at doing some of them, doesn't seem impossible hardware wise?

Look forward to your thoughts
