Solo LED Feedback with Launch Control XL and Digitakt

Hello there!

I am currently facing the exact same problem with the digitakt.
I have very little knowledge in programming.

  • My digitakt is configured as each pad being a specific midi channel
  • The launch control xl’s pad’s are set to send a CC type message: CC94 (Toggle mode: Min:0 Max:127) - each pad to it’s specific midi channel. - I saw somewhere that it is because it doesn’t trigger does lights with cc mmessages; only with Note messages.

How could I get the leds to lighten up?

Hi and welcome to the Bome community!

I split this into a new posting because it is related to a different device than the original posting.

The attached should work or get you close to what you want.

Preset 0 is just regular project initialization stuff that I put in most of my projects but not related to your question.

I have my aliases set up as follows (for testing) you will need to point them to your actual devices.

You can learn more about aliases from this tutorial.

I set up routing different at each preset level. Preset 1 handles messages from you controller to your Digitakt. Preset 2 handles local feedback from your controller and back to your controller.
Preset 3 handles MIDI messages from your Digitakt to your controller.

For more information about device selection, see this tutorial.

The translator in preset 1 converts a CC message to a Note message for the Digitakt.

The translator in preset 2 handles local feedback from the controller and is only needed if the Digitakt does not provide feedback with the same note as received.

The translator in preset 3 handles feedback from the Digitakt to the controller and should only be used if the Digitakt sends feedback.

So essentially, depending on your Digitakt capability, you need only preset 2 or preset 3 enable.

In the rules of the feedback translators, I have this will which determine the on or off color to send back to the Controller.

// Set desired colors here
// off color green
if qq==0 then tt=60
// on color red
else tt=15

For the translator in preset 3, I am using raw MIDI for input so it can handle both note-on and note-off messages from the Digitakt
Raw MIDI is “oo pp qq”. I look at oo to see if it is a note message. This allows me to only use one translator instead of two.

// Look for note message
rr=oo&224
// If not a note-on or off, do nothin
if rr!=128 then exit rules, skip Outgoing Action

I also set up some MIDI thru routing so that anything without a translator will go through those paths untouched. The translator have the ‘Swallow’ option set so that the translated messages will not use the MIDI thru routing.

Wow that was a quick response!
Will look into it to let you know how it went!

Thank you so much for your time!

I figured a way to make you preset work.
I din’t need feedback from the Digitakt.

But I think my patchwork is not so good as my Bome box or Just the LaunchControl XL keep restarting.

I just want the Launch Control XL to Light green or red according to the Digitakt’s mute channels ; and receive feedback from itself - and

Link with my project file

After it restarts, sometimes it stops working until I reconnect the midi and usb cables to my devices.
I would like to use this set up live but I can’t use it like this.

I am providing current thru a usb-c charager - 25w - a usb-c to usb-a little dongle and the usb cable.
The same was happening when I was powering it with a usb 2.0 -2w- powerbrick.

Might the problem come from my project or from the bomebox beeing damaged?

Thank you for your time.

Best regards,
Diogo

Hi,

Without consistent power, you will likely see strange results. Charging hubs often manipulate the power provided in order to help charge devices quicker. If you use any power source that manipulates the power in this manner, BomeBox will intermittently re-start. During the restart process if the power is still not consistent, you will get mixed results.

I suggest you try either a powered USB hub (with no fast charging ports), or a POE (power over ethernet) adapter to power your BomeBox. If you use a power brick, you need to check to make sure that it doesn’t have any fast charging option. I have always had the best results with a POE adapter. POE also ensure there is a lock tab to ensure it doesn’t get bumped loose.

I doubt any of the devices you tried to power your BomeBox caused any harm to it as it has built in protection.

On your MIDI thru routes, I assume your BomeBox DIN out is your Digitakt. What is connected to BomeBox DIN in? I see you have a route to also send though to your DIN out port.

I see also that any MIDI messages that don’t use a translator will get routed from your Launch Control XL, straight back to it. I’m don’t think that routing is needed as most controls on your LCXL will ignore them anyway. I suggest you remove that routing and add translators for any other buttons you want to light up instead.

I would also give your devices alias names as it would be easier to just re-assign them depending on whether the project is running on a computer or BomeBox.

You can learn more about aliases from this tutorial.
