AKAI APC 40 change LED-Ring config.

**s:mode** · 01-10-2010, 09:44 AM

Hello everyone,

i've already searched for a while. But either I'm using the wrong Keywords or this questions is not answered yet.

I try to reconfig. the "track control" knobs on my APC40 in "ableton live". What i try to do is to link knob 1-4 to 3-band-eq + cutoff of 1 Audio and 5-8 to the same of 2 Audio. I am using the ordinary Midi learn function.

It works so far, but the LED-Rings 5 to 8 don't show anything.
Is there a way to configure the LED-Rings.

THX for your help

Hi, I´m also trying to figure out this. I Want to get all my led rings to start from the middle like a normal mid/bass/treble knob. Any help will be highly appreachiated! You get looooads of karma!

You need to also program the MIDI Out function. This is usually the same as the MIDI In but if your using Traktors default MIDI mapper then the LEARN function doesn't work for MIDI Out, you must enter it manually. MIDI Out functions are the LED feedback on all controllers. If you really want to get into making detailed custom mappings for any controller I would suggest picking up the Trakor Bible. It can be found at HTTP://www.TraktorBible.com

It covers everything and is written really well for someone who has never done MIDI mapping before and well worth the investment.

Hi Bartyboy, thanks for the tip, will definetly look into the bible. I am not new to mapping though, have figured out how to map the output button to red/green/blinking etc... But I can't really figure out what you have to send to the midi out to map the led on the knob, normally goes from 0-10 but I want it to start in the middle. 0-5 and 0-(-5). It doesn't seam to be that simple as the buttons. Anyone have some experience with this?

If I remember correctly you have to add 8 to the CC value for output to the LED rings.
For instance, you have CC40 controlling highs, to map the LED ring map a midi out to CC48.

OP says Ableton Live, the first reply doesn't specify, and everyone else says Traktor. I'm confused here.
(And talk about reviving a dead thread. :U)

Anyway, this PDF provides information that all APC20/40 users should have handy: http://www.akaipro.com/extras/produc...ocol_rev_1.pdf

Page 11 and 12 have the information you need. If we are still talking about Traktor here, then the "Midi Range" of the output control you are looking for needs to be set to 3, for "Pan Style". I did this with my APC40 just now. Here's some screenshots of the settings in Traktor:

Like I wrote earlier, 3 is for Pan Style; 2 is for Volume Style; 1 is for Single; and 0 is off.

Quick example of the mixer section:

I mapped the top row of knobs to deck A, and the bottom to deck B. From left to right, they control the Filter, Low, Mid, and High. Deck B's High is on Pan Style, Mid is on Volume Style, Low is on Single, and the Filter is off.

Hope this helps. :U

Thanks Onimode! Really nice I will get right on it when I get home!

Really sorry to s:mode, I think I hijacked his post, I was looking for apc40 and Traktor on this thanks!

I'm happy to help. And I don't think s:mode is going to mind, since this thread is over a year old and this was his only post. :P
