Launchpad Pro MK3?

[mxmilkiib]

Hi! I've a Launchpad Pro MK3 and I'm looking to use it with Mixxx, and I'm up for helping with the process of getting this working, debugging and making PRs, though I'm not a programmer, just a scripter ;) My dream would be somehow to get 16 hotcues, but I realise that's something for further down the road. I've seen #13 and I'll begin the process of grokking the project as a side project.

It looks similar to Launchpad Mini MK3, just with more buttons. I would start by adapting the mini mk3 code. I think the main chunk of work here is to figure out what to do with the additional buttons. One idea from the top of my head is to use some of them to lay out effect units on the grid. I'm opinionated to support only button controls, but these could be button parameters / effect selectors, etc. E.g. we could have an effectSelector similar that is similar to the current channelSelector. We could make this customizable, on a Pro, that has enough buttons for both, both channels and effects could be laid out on the main grid (e.g top row: channel selector, left column: effect selector). For smaller controller, the user could customize to use the top row to any of these. Just one idea. The bottom rows could be used for UI controls for example.
