Hi Kazz,
Feel free to try this driver below. I used the apckey25 driver as the template and brought in some of the functionality.
Since then I have made an updated one with volume and pan functionality (though it uses the pro’s extra buttons so you’d have to dive in and changes a couple of things). I never got the note input mode working properly though, couldn’t figure it out. If you want to try that, let me know.
A unified driver for all the launchpads could be cool so they can share functionality but it needs someone with the skills to make it work.
