Clear displays / turn off backlight of MK3?

[mrvnklm]

Hey there, I tried out the example / tests for MK3 and they work so far. As I am not into hardware level coding, I am wondering if you could help me to clear and turn off the screens, as I use the maschine as my daily audio interface?

@mrvnklm Restating my understanding of your request: Most of the time you use your Mk3 as an audio interface and aren't using its screens and so you'd like to be able to effectively turn them off by clearing them and turning off the backlight.

If you replace the image examples/maschine_mk3/placeholder.jpeg with an all-black image and run the example via npm run example:maschinemk3:node that should clear the screen. I don't think we currently know how to change the backlight brightness via the protocol, however. Someone would need to look into that, but it might involve capturing the USB traffic of NI software changing the brightness using software like Wireshark. It's also possible other software has already figured this out, like https://github.com/shaduzlabs/cabl.

Note that you may need to terminate some NI helper process if it's tying up the display endpoints on the Mk3.

Alright, thank you! I will look into that.
