Akai APC40 and traktor pro, full midi maping incl. led lights and led rings work

Hello, :)

I have an APC40 and i did all midi mappings in traktor pro. I made leds on clip lunch buttons, and even led rings to work in pan/volume stile.

I have an M-audio Fast track pro an HP notebook with 4 GB ram, and dual core 2.2GHz (XP sp3)
Everything is working fine except i have audio crackling on low latencies...
if I go to 10ms i hear crackling. On 40ms and more sound is perfect.
I think the problem is when traktor sending midi to APC. Those output midi messages for controlling leds on APC. When I turn them of everything is ok.
Is there anyone with same or similar problem?

Also if there are interested in my mapping i am happy to share...
Apc is mapped for all things, looping, hot-cueing, internal mixining an eq...

sorry for my bad english :)

Always interested in trying mappings; hit it!

I had the same problem. It has something to do with the mapping of the leds. If you are using send monitor states you get crackling in the audio so if you are using them dont. Your latency should be alot lower than 10ms. I got mine down to 2ms using an audio 2dj

hm, 2ms is realy low, and i think that is impossible, even for much better computers in for studio use. I have 2,5ms in traktor pro when not using midi controler...

How much latency do you have in Ableton for example?

hi buzz, i got a macbook and never had issues with the latency, but my mapping on the apc is really really simple and I don't use it much. I use the x1 controler for gigs. If you want I could test it with my setup.. maybe it's really a hardware issue.

greets luca

PS: my english is also bad.. :) where u from?

I dont use ableton on that computer really but i got i down to 2 ms with traktor and im using a Dell, apc 40 and oxygen 8 with an audio 2 dj. I had the same problem with the set up when i had all the leds mapped using send monitor states. I deleted all the send monitor states and mapped the leds normally and i didnt have anymore audio problems

@lucadegrandis

I will post my mapping in next couple days.. I am planing to put video on youtube with some explanations, because this is mapping for internal mixing, and it is completely controls almost everything in traktor. I did not see that before on share...

Im from Bosnia.

@jimsimp59

When I turn of out midi messages i also have 2.5ms of latency in traktor :)

I think that is just some trick, because when i using apc with ableton everything running normal on 10ms latency or lower.

But I am satisfied with 20 or 40ms. Latency of 40ms i only 0.04 seconds of delay when i press control and time when traktor do playback. So it is really blink of eye :cool:
I have a gig tonight and Ill try everything on stage :)

I d really like to look at your mapping to see how you mapped your leds. I cant get them to act how I want them to but they are working. I use my memory. What sound card are you using?

Why dont you post the mapping so people can have a look at it?

Hey , i would like to have your TSI, send to my email plis, chavez_cota_sasha@hotmail.com

Thanks!

I had a microkontrol mapped for traktor
switched to apc 40 and traktor stopped receiving messages (it sees the controller - but when you clik on learn + push a key on the keyboard, nothing happens)

I went back to microkontrol and that stopped sending messages too (to traktor) - I tried other controllers.

m-audio o2, evolution uc-33, x-session

nothing...on another note - everything work fine (on the same computer) with ableton, garage band...

it's just that - traktor stopped receiving midi messages...

i uninstalled, reinstalled, reinstalled difeerent versions, even removed using the un-install utility


ANY OPINIONS >> ?? - hello to everyone too . . .:D

I'd also love to have a look at your mapping. I've tried several others, and none are close to what I'm looking for. Please send to djginkgo@gmail.com

Can you sent me the mappings please. I want to take a look at them.

Im working on my own as well, but I would like to check yours out if possible? Thanks!

portmanotaku@gmail.com

Hi Guys, Just purchased a brand spakin' new apc40.. is it possible for you guys to send the mappings over to me too? radrad (at) gmail (dot) com.

Thank you so much. :)

i guess we're all waiting for the mapping...
i am too ;)

hello to everyone :)

I see there is many people interested in my mapping.
Send me email on cyclesix at gmail dot com, and i will send you tsi, and pdf with some explanation. I didn't use "send monitor state", but all leds are working pretty good. I had several gigs with this setup, and no glitches, sound problems, etc... using just HP530 with 4 gigs of RAM, M-audio fast track pro, APC40 and of course TP 4decks :D
My friend with Macbook pro, and X1 had 2 serious drop outs :) he was playing before me at two parties... :D

I planing to post video demonstration on youtube.. i need to catch some time :)

Hi, Could I have a copy of your TSI. file ???? I would love to see how you were able to do this .

Thank you,

Rodrigo Peraza

HERE IS MY E-MAIL : rodrigo.peraza.jr@gmail.com

Hi Buzz,

I got the TSI file you sent. :) however I need a few clarifications, I tried using the FX2 button on the mapping unfortunately I can't seem to make it work..

I am hoping you are able to do a quick demo maybe on video? if possible? :) sorry i know you put a lot of work into this :) btw, it's one of the most complete mappings i've seen thus far. :)

I currently working on new tsi, with full control for FX1, FX2 and FX3. (FX4 is always Digital LoFi)

I am trying to catch time to record some demo video... hope it will be soon:)

looking forward to it :) awesomeness :)

Here is some pictures how it works...

I've tried around 10 traktor apc40 mappings so far, and while some have satisfied certain needs, nothing has been comprehensive. This looks amazing. Do you have a .tsi we can play with?

Also this is sort of unrelated, but I can't seem to get the x-fader and sometimes deck volume sliders to appear onscreen or work in any of the .tsi files that I've tried. The crossfader works in ableton just fine so it can't be broken, and I've double checked the mappings and they look correct. Any suggestions for the time being while we wait for you to upload your mapping? :)

well for those of you wondering 2ms is pretty common for high quality sound cards and is usb's lowest cabable im pretty sure, but firewire can go lower, even my stanton final scratch box goes down to 1.5ms

what's up fellow APC40 users!!?? I've had this thing for about 3 months now and am finnally starting to get my personal mapping to a point that is useable. but i've been banging my head on my deyboard trying to figure out these silly led states. Anyhoo, the pix of the TSI look pretty awesome, and I'd ove to test it out.

de4ek at mac dot com

thanks in advance!!!:)

Would love to try this out, please email it to me at cameron.kollwitz@gmail.com

Are you confused about the LED states of the rubber pads or the knobs? I MIGHT be able to help with regards to the knobs on the right side, just create a new "out" on traktor and add 8 to the knob channel to control the lights.. sorry if my instructions are a incomprehensible, I'm at work and just sneaking in to help a fellow confused brother out. hehe!

I'll get into it later when I get home.

Cheers.

i've not even started tinkering with the knobs yet. but eventually i'll need that info too. I have read the tutorials online, one give an example where a button is used for a cuepoint. when there is not a cuepoint mapped to that button it should be red, and if a cuepoint has been set for said button it should be green. although the numbers for the colors in the tutorial were incorrect i figured that out. but after i push the cuepoint button the backlight goes away..... help~

I'd love to get my hand on the OP's TSI. if someone has it please email me at de4ek at mac dot com :cool:

thank you.

ok... i think i figured this cuepoint button thing out. you need two outs. one for Hotcue state and one for select/set+store . and then the right combo of numbers for what light s you want. hahahahaha! i don't have a modifer yet and am wondering how the led feedback will be effected when i do start to fiddle with the modifers.

or not.... man these leds are crazy! why doesn't NI have better doc's on this!!!? i started mapping my new findings to my deck a cuepoint buttons after 3 i decided to check if they were really working. yes, but no. and it's so weird its gonna be pretty hard to describe. maybe i can post a video... idk

@de4ek

You know that the APC40 needs to be in some other 'mode' don't you? Your problems sound like normal APC40 behaviour (=LEDs go off after clicking on it).

Did you try to
1) Power on your APC40
2) Go to Ableton Live (wait for the red box)
3) Close Ableton
4) Go to Traktor

Now your TSI will definitely behave totally different.. Did you try this already?

What is this mysterious red box...I've opened Ableton and have no clue what to look for (rarely use it as it's APC edition)

ty

It's more a red rectangle,

See: http://www.production-room.com/gfx/p...-apc40---2.jpg
(check out the red border rectangle on the top right around those clips)

This box is shown as default after installing the Ableton APC edition. You can turn it on/off in the MIDI setting, I guess it must be on to make sure this 4-steps-into-dumb-mode process works).

I already made a short movie-clip on this, but need to upload it to youtube first (maybe tonight).

@Buzz

Checked out your .tsi, thank you for sending it! GOOD STUFF!

The main reason I checked it out was to see how you got the LED rings to work, because every time I tried to assign the OUT in a Pan or Volume style, the encoders wouldn't work. For example, if I assigned filter to a knob/encoder, then assigned an OUT to that same knob/encoder, the filter would stay stationary in Traktor along with the LED position on the encoder, rendering it useless. Im not sure if I was doing anything wrong or if it was a limitation of the APC40.

But I checked your file and hats off to you for the way you did it. I wasn't aware that each encoder has multiple CC notes on one channel. You assigned a filter for one encoder, such as Ch.01 CC 48, and then for the LED OUT, you would assign that same physical encoder an OUT but it would have a different CC note, for instance Ch.01 CC 56, and they wouldn't conflict. How did you figure that out?

And also it would be very helpful if someone could explain the different modes of the APC40 (Native, Dumb, etc) and their differences?

THANKS! Ill post my APC40 mapping soon!

@ Timmio
right on right on...thanks mate! :D

@Space

You're welcome :D

...!

Note that LED rings always are +8 notes higher. So if you map the control to CC40, the LED is connected to CC48, Also I guess there is no control who uses CC48. So just remember, when playing with LEDS on the CC-note side always add 8 to the number.

Regarding the APC modes, check out the posting from Zac:

Experiment with all of the three "states" of the APC40: "Native" (red box) mode (Turn on APC, Start up Live, select APC as control surface). Non-native mode (don't turn on Live, or don't use APC as control surface in Live). And "Dumb" mode (Get the red box in Live, then quit Live). Each state does different things with midi and led feedback.

(see http://www.djtechtools.com/forum/sho...d.php?p=117419)

I'm almost done with some awesome remapping my APC using various advanced filter modes (stolen from the great guy who developed the midi fighter TSI, I borrowed their advanced filter handling :))

WIll post a movie soon :)

edit: Check out my mini movie on setting the dumb-mode:

I am relay glad to know that you like my mapping, and that you can use it in your work.
I figured out almost everything... apc mods, in and out midi messages from TP, but only one thing is still problem. How to make traktor sending state of the knob, for exapmle to send state of filter knob to apc...
When I map filter on CH1 CC48, send pan style message to apc knob CH1 CC56, and try to send filter state to led ring CH1 CC48, it is working but not correctly. Knob get stucking and not working correctly.

Any one make this working???

Buzz,

Did you map the values correctly?
01=single style
02=all leds
03=pan style

(again Zac is the real Hero expert in this, check his post: http://www.djtechtools.com/forum/sho...d.php?p=110454)

Yes, i mapped it correctly and it is ok. But, when i trying to send state of the filter or some other knob inside traktor to APC, there is problem.

I did not gave correct example.

Let say that i want to send 3 eq state for every of 4 decks to only 3 knobs on APC.
when i select deck A on apc should show state of deck eq. then when i select deck B, on same knobs to show state of deck B eq.

sorry my english is bad :D
