Possible to set LED level on some other buttons

[riban-bw]

There are 4 buttons that can have their white LED turned on at various levels:

• Launch (CC 104)
• Stop / Solo / Mute (CC 105)
• Play (CC 115)
• Record (CC 117)

Each may be illuminated by sending CC with value parameter defining brightness:

• 0-31 0% (off)
• 32-47 25%
• 48-63 50%
• 64-95 75%
• 96-127 100% (full on)

Yes! I remember that Stop/Solo/Mute can be colored to yellow/blue/red but I forgot to investigate that further!
I will check that tomorrow, should I add that info and credit you like before or you will make PR?

[riban-bw]

You can just add it. I can't be bothered to fork, edit, PR. I have loads of forks I need to tidy up for simple PRs like this. (There must be a better way!!!)

I haven't figured out how to change colours of the buttons. I notice the 25% illumination looks purple but that might just be how they encode the brightness.

Thanks for investigating and maintaining this repo. It is proving very useful in my integration work hence feedback to you of anything else I find so that other's may also benefit.

Colour of launch and stop/solo/mute buttons can be set by sending CC to channel 1. Doesn't seem to work for play or record button.

Setting colour and brightness are mutually exclusive, i.e. setting brightness will change to white and setting colour will change to the corresponding colour / brightness from the colour table.

Alright I will update it tomorrow. I will try to find other colors too, just remembered that Ableton changes Stop/Solo/Mute colors, maybe other can be changed too.

I couldn't find info about it online so I decided to do small research and write tutorial for others

Alright, are there more colors than yellow, blue and red?

[riban-bw]

All the colours in the colour chart seem to be valid, e.g. sending value 95 will light the button hot pink.

Great!

[riban-bw]

Sending colour on channel 2 flashes and on channel 3 pulses, similar to sending note on commands to the 16 pads.

[riban-bw]

Sending brightness to the play and record buttons on channels 0, 1, 2 trigger solid, flashing, pulsing behaviour.
[Edit] There is something odd about the values though. Sending value 1 seems to pulse brighter than sending value 127.

[riban-bw]

Although this is maybe could be regarded a different ticket, whilst in the README it may be worth mentioning that the shift key state is represented by CC 108. When pressed it sends value 127 and when released, value 0. If double pressed it will send value 127 until pressed again when it sends value 0. This allows you to use the shift status including the shift lock - rather useful. I am using it to bank the 8 knobs between two different offsets.

Just updated README and added example for changing brightness.
Please check if there are any mistakes.
Thank you for your help as always!

[riban-bw]

You only show 2 examples for colouring buttons which might confuse as there are 3 modes: solid, pulsing & flashing.

You haven't mentioned being able to set these 3 modes for play / record buttons.
