Akai Apc 40: No Led-Feedback

[Mondmöwe]

Hi,
I need help with my Midi-Controller: Akai apc 40
Arena Resolume 7.21.3
MacbookPro M2 Max, 2021, Sonoma 14.6.1

I have an old Akai Apc 40 controller:, which I got from a friend. I can do the midi-mapping, knobs & buttons are working, but there is no light-feedback to the controller. So even if I press a button > the clip is playing, the button wont light up to show which clip is played
I checked in the preferences Midi Output is activated.
Is there an option to make this work? and if not is there an other controller that works smoother?

Thanks in advance

I already checked the internet & ChatGpt, haven’t found a solution yet.

Did you only activate the output channel or did you also map it?
If not here is a video that might help. It's for the APC40mk2 but the workflow should be the same.

In resolume you need to set the midi clock out, so it sends midi back to your APC40 Mll.

If that does not do anything it is possible that there some resistor lose on the print board of you APC40.
That can easily happen, APC40 Mll are not shock proof. Had to get mein fixed after a slow drop of 50cm.

Hi thanks for your answers.

It’ an older Controller – not a MK2-
I couldn’t find the Midi Clock Out, Just Midi Input, Output & Clock in.
I mapped my Midi & it’s the third of those controllers I checked all of them have the same issue (they are working fine, besides the not working LED-Feedback).

Does the MK2 work without problems, and if I connect it does a Midi Clock show up in the preferences, if so. Maybe it’s time for me to get that one.

Thanks a lot

Midi Clock is not needed but you need to activate MIDI Input AND MIDI Output. In the video I posted at around 4:40 he tells how to set the light.

For Clips the state names are different:
- Empty (when there is nothing on the Clip)
- Disconnect (there is a Clip but is not playing)
- Previewing (selected Clip is in Preview Mode)
- Connected (this is when the Clip is playing)
- Connected & previewing (both of the above)

Since I only have the mk2 I don't know for sure it's working on the original APC40 but I would definitely think so. So normally you should only have the option lights on/off maybe there are 127 velocity options available for brightness of the light.
