Understanding Push's button color codes

Post by patrickstinson » Mon Sep 15, 2014 8:08 am

I am trying to get a button to pulse smoothly from bright green to the darkest green, sort of like fading opacity. The problem is that there appears to be no rhyme or reason to the Push color codes, so I can't find a way to do this with math.

Does anyone understand how this works? I have tried reading the _Framework classes several times (and I am an experienced professional Python developer) but can't figure this part out.

Bottom line, what are the color codes to fade a color in and out?

Thanks!

I may be completely off here since you are talking about scripting and not simple MIDI output to the unit but isn't it a matter of note velocity?

I did reference the scripting framework classes, but this topic is for sending color values using M4L via the control surface API (which yes, is defined by Ableton's scripts).

Setting a button's color is easy, you just call send_value <row> <col> <color> to the button. The problem is that there is no consistency in the ordering of the color code values themselves. For example there appears to be several shades of red but they are scattered all over the integer range of 0-127 with no coherent pattern. For example, if all the reds were defined by the values 0-5 in order of opacity, and the greens 6-10 in order of opacity, fading a color would be simple addition or subtraction. But this is not the case.

I hope that clarifies.

Could you use 'dict' or something similar to create a library in the order you want? It would mean going through all the values for Push manually, but would only need doing once.

I'd just use a jitter grid?

dict has remained beyond me to date, probably need a lesson ;-)

That's the closest thing I've found for this yet! Although I'm not sure what to do with these "fast" "slow" and "blink" values since just sending them to the grid as is will not produce animations. Where did you find this, and is there anything else that goes with it? I am having trouble finding contact info for Mark himself.

For slow blinking (pulsating) you need to send the color(note) on midi channel 10.
For fast blinking you need to send the note on midi channel 14.
Before that you need to send the base color on midi channel 0.

Found that out by experimenting. You can also take a look at my Bitwig script: https://github.com/git-moss/Push4Bitwig/
See the files Grid.js and Colors.js

Woah, cool. I'll check out your code. So sending a code over midi implies that the fading and blinking functionality is built into Push or it's python script? I assume these values don't apply when using the control_surfaces Button_Matrix interface when using M4L (which is what I'm using)?

Again, I am surprised and impressed to get such feedback, I've been messing with this for months!

The Mark Egloff pataches were from the Cycling 74 website from memory...

It is in the Hardware.

Only had a quick look some time ago. I guess they do the same internally.
