I'd like to "grab" the whole bottom row of my LP Mini so in any context (in session mode) they behave like 8 stop button and 1 "stop all clips" button.

How is that doable ? How to target the row ?

Thanks !


grab-a-launchpad-control

I'm not sure that the grab/release control functionality is present in any other controller but Push/Push 2, so you might have a bit more work ahead of you.

What script does that use?

I've dig into the controls and figured out they are controls 58 to 65 plus 82.

print: info type ConfigurableButtonElement

print: info description Special button class that can be configured with custom on- and off-values

print: info child canonical_parent Launchpad

print: info property mapping_sensitivity float

print: info property num_delayed_messages int

print: info property optimized_send_midi bool

print: info property proxied_interface ProxiedInterface

print: info property resource StackingResource

print: info property send_depends_on_forwarding bool

print: info property suppress_script_forwarding bool

print: info function clear_value_listeners

print: info function message_sysex_identifier

print: info function notify_ownership_change

print: info function script_wants_forwarding

print: info function set_force_next_value

The function is_pressed gives me its state but it's not relevant because i would need to call it. It don't get how to "observe" its state.

Also i'd like to observe what Mode is selected so this would be a special button behavior only when session mode is selected.

That's why i put the "" before "grab" !
It's standard Launchpad script.

Check the 'mode_index' of the MainModesComponent of the script.

There's not an easy way (that I know of off the top of my head) to disable the native functionality of a button in the LP script. So it will still trigger the clip, along with whatever functionality you define. You might need to dig a bit into the script find the id of that clip slot of the matrix and disconnect it that way. Or something...Good luck!

All buttons have a 'value' property.

I might go the easy way and make a UI to manually map those 9 buttons. That would save me a lot of programming and it will still be quite fast to map. And i can save it to my default liveset as well !

Yeah, that's a possibility. But with the M4L way, you could do some meaningful stuff with the LEDs.

You could do some javascript code to make this all pretty quick and neat.

I think MIDI mapping them disables their component action but they can still be accessed by M4L. Didn't try yet.

Ah yes, you're right. I wonder how that's handled from the script side...that functionality must be available from the API, but it's not important enough to me for me to keep digging ;)

Well, it appears that when a matrix button is MIDI mapped to something, i cannot change it's led state anymore.....

Annoying since if there is any clip in the 8th scene when i load the set, it lit's their buttons in the LP. And i'd like to have this bottom row unlit, or all the same color. Any hint ?

Here's the device, in case you'd like to help...

Honestly I'd probably just modify the script. It would be pretty trivial to remove those buttons from clip launching, and make them stop buttons.

Damn you're right.
But i have no clue how to do this...


EEK! Neither did I at one point. The trick is getting the decompiled script from github: 

https://github.com/gluon/AbletonLive9_RemoteScripts

to not throw any errors, and then it's just changing a few lines of code to remove the lower row of buttons from being assigned to clips, and then assigning them to the buttons in the script, or leaving them unassigned. and you can do the mappin in M4L.

Damn i hate this feeling when i get some very partial understanding, just looking at the code, but have no clue where to begin...

(i'd drop a few bucks if you'd make this custom script, with some explanations. Don't know how to send a private message here).

Yeah we should be able to work something out. I'm getting off the grid till Sunday, but we'll reconnect then and figure something out.

It's very possible to make the patch / max for live device you're after. And not too tricky a task.

You want to send "call set_enabled 0" to each button to disable it's standard behaviour. You then want to set up a [live.observer] property to monitor the button presses.

You can set the LEDs by setting the "send_value" function of each button.

You'll also want to monitor, but not disable, the left and right buttons of the top row of buttons. The ones which let you move the Session Highlight Ring / Track focus left and right. This is how you'd make sure the Track Stops are stopping the correct Tracks.

You would also want to set up a metronome to regularly get the Session Highlight box position to make sure you have the right Track index / offset. This is because if you enable MIDI map the Session Highlight Ring will be set back to 0 0, so you're calculations based on the top row button presses may be off. You can find this in the Session_Control component, the "track_offset" function.

Hope this helps. I'd be happy to help you program further, edit your device, or make the device for you for a fee for my time.

Either way hope you get it working how you want! :)

Ahh forgot to mention you monitor the button presses by using a [live.observer] with the propery "value", the ID of [live.observer] set to the ID of the button to be monitored.

That's so helpful. Many thanks for taking the time to explain. I think i should sort it out by myself now.

No worries. Good luck! Hope it goes well :)

"grab" a Launchpad control ?
