Hi Franta, I've just submitted mixer quirks for the 900NXS2, following the design of Olivia and you. Seems quite clean, but if anyone comes up with a clever idea on how to share code between the channel arrays, I'd highly appreciate that. My experiments so far turned out quite complex: I thought about adding flags like "DEVICE_HAS_DIGITAL", "DEVICE_HAS_AUX" etc. which are evaluated during control creation and usage. The code became unreadable and complex, so I ditched that idea. Creating the controls arrays dynamically would maybe help. The 900NXS2 uses the same wValue/wIndex as your 250Mk2, just expanded to five channels. It does not allow to set playback channels via USB, that can only be done in hardware using the input source knob. I guess that is same for the DJM-700. The 900NXS2 allows querying the currently selected playback channel though, but I think this is of no great use so I did not implement it in this patch (although it was in my original draft from last year: https:// gist.github.com/flesniak/074ab23bbc833663b782f44174eae6a4). If you think it's worth it, I could have a look at that again. Cheers Fabian Am Montag, 1.
