APC40 LED trouble

**SqueakDemon** · 10-11-2011, 11:25 AM

Ok, so I'm mapping my APC 40 for TP2 and everything seems to be going fine until I try to map the outputs for the LEDs. I can get them to be the right color and everything, but the led activity is very unpredictable. I can't get the lights to actually stay on.

For example: Say I would like the LED of my play/pause button to be red when paused and green while playing. I can get the colors fine, but no matter what I do the LED's just turn off if I hit the button. once in a while they will stay on and it will work for a second, but when I hit the button again it will only stay lit if it is held. I've made sure that my button is set to toggle, and the function works fine, It's just the led's giving me trouble.

Controller range is 0/1
Midi Range is 4/2 (Flashing red, Flashing green)

Am I a complete idiot or is there something I am missing? any help would be grand. thanks

It tends to work if i hit the button lightly and quickly, but the average button press causes the LED's to turn off?????!!!!

2 things could help out.

select invert
then add in a update state.

My mapping work fine without invert, but worth try the above, but the most important is to make sure you are in dumb mode.

From my experience sometimes even though you start in dumb mode after change some mapping setting the LEDs start to acting weird until I restart the APC and traktor once again in dumb mode then it work fine.

what is dumb mode?

and how would I go about adding an update state?

Search Youtube for APC40 dumb mode. It is in dumb mode when there is a red rectangle around the first couple channels in Live.

To start in dumb mode you have to:

1 – Turn the ACP40 on,
2 – Open Ableton (make sure the red rectangle is displayed),
3 – Close Ableton,
4 – Open Traktor.
Done

Do an add in then go to global and select update state, now click on learn. Your done.

ok so I've just had the chance to try this stuff out.
When I try starting ableton before traktor all LED feedback in general goes off when I close Live.
Also, when I look for the "update state command, I Cant seem to find it. It's not under "global" all I have are:

Snap mode
quantize
broadcasting
cruise mode
show slider values
FX panel mode
send monitor state
