Collision Mapping Manualfor APC40

1Introduction

2WelcomeHello Everyone! My name is C.Lab. Over the last two years I have been working on the Collision Mapping for the APC40 and Traktor. Im thrilled that you have an interest in DJing with the APC40, and hope that this mapping will get you headed in the right direction!

The BackstoryI began writing the Collision Mapping out of necessity. I owned an APC40 that I used for music production in Ableton Live. One day i stumbled across DJTT and was instantly intrigued. DJing, Traktor, and Controllerism seemed all too exciting, but i didnt have any extra cash laying around for a DJ controller. (since i just spent it all on the APC40) So i set out to design my control-ler mapping. This would allow to me design the controller to cus-tom fit my needs. I started off by listing out all of the features I wanted to have control over. Then, for each of the these con-trols i decided how i wanted to interact with it (ex. Knob, Fader, Button etc.). Then the only thing left to do was group the con-

trols into sections and determine how to lay them out across the controller.

You Can Too!!!When i began this project i knew next to nothing about DJing or midi mapping. If you have any interest in editing or writing map-pings for your controllers check out these articles. They taught me everything I know!

This article is CRUCIAL! It explains modifier basics in easy to learn way.

This is more of the same modifier stuff. Just a little more in depth.

Here you can learn about writing Super Combos. Even if you dont plan on using them, this is a GREAT read for midi mappers.

Everything you ever need to know about Mapping Outs to LEDs is right here.

Section 1

Hey!

3General LayoutThere are basically two kinds of controls in the Collision Map-ping. There are Global Controls that will all stay the same. By this, i mean that whatever parameter that is currently being con-trol will never change. (Ex. Knob 1 controls high EQ, and will AL-WAYS control high EQ.) Aside from Globals, there are parame-ters that i refer to as Pages, or Banks. They are pretty much the same. Pages refers to groups of buttons, and Banks refer to groups of knobs, but the concept is similar with both. Depend-ing on which modifier key is selected, the group of controls will function differently. Ex. FX unit 1&2 modifier key is pressed. This will cause the lower bank of eight knobs to control FX 1&2. However, pressing the FX unit 3&4 modifier will cause the same group of knobs to control FX 3&4. The concept works exactly the same for groups of buttons also known as Pages.

Overview

2Installation

Basic Steps

1. Download CollisionMapping.Zip from DJTT Maps. This will include the demo mapping, link to upgrade to full version, and this manual.

2. Connect APC40 to the computer and turn on. NOTE: if the APC40 has been connected to Ableton if must be turned off once before connecting to Traktor. Otherwise you will experience erratic behavior.

3. Open Traktor and navigate to Preferences> Controller Manager.

4. Click the large import button at the bottom of the window and select the provided .TSI file.

5. Click OK when prompted.6. Repeat steps 4 & 5 exactly. DO NOT SKIP THIS

STEP! 7. Make sure both the Inputs and Outputs in the

controller manager are set to APC40.

7Browsing through tracks...In your normal view a small box at the bottom of the screen con-tains all your tracks. This can be scrolled through by using the cue level knob. For more efficient browsing i created Browser Mode. Lets see how it works...

Browser Mode- Toggles browser mode on and off. When in browser mode the tracks list will be made full screen.

Cue Level- Allows you to scroll through the list of tracks.

Up & Down- Allows you to move up and down in the list of mu-sic folders to the left of the track list.

Close & Open- Pressing these buttons while a music folder is selected will either expand or collapse the folder.

Fullscreen- Toggles Traktor fullscreen mode.

Load A & B- These buttons will load the currently selected song into each respective deck.

8Basic ControlsThe top two rows of the 8x5 grid contain all the transport con-trols for decks A and B. They look something like this...

Play- Works just like any other play button. When the track is

stopped it will light up RED. While the track is playing the button will display GREEN. Holding SHIFT and Play will send the play-head to the beginning of the track.

Cue- Your standard cue functionality.

Auto Loop- Auto loop sets and activates the loop function in Traktor. The loop length will default to the current loop length se-lection. We will talk more about this later. This button displays YELLOW while loop is off and flashes RED when loop is on.

Sync- This button toggles the track sync on and off. This button displays YELLOW for off and RED for on. When SHIFT is pressed this button will set the track as Master.

Nudges & BeatJumps- The regular old nudge commands. When SHIFT is pressed these button serve as beatjumps. The length of the beatjumps are determined by the loop length selec-tor.

Key Up & Down- Probably my favorite new feature, pressing one of these buttons will transpose the track up or down by one semitone. This allows for WAY MORE FLEXIBLE harmonic mix-ing!!! (ex. Need a track in G, but want to play a song in E. Press-ing the Key Up button 3 times will put the desired track in the key of G)

Section 1

Transports

9Upper 8 KnobsThe Upper grouping of knobs is dedicated to the EQs and fil-ters of track Decks A & B. They are arranged as depicted be-low. Since these controls are global they will never change.

All the EQ knobs function just like the software mixer. All the way to the left is 0 and all the way to the right is 100. The LED rings reflect these values.

The Filter knobs at the center position are at zero. Turning to the left engages a Low Pass Filter, and turning to the right en-gages a High Pass Filter.

NOTE: The standard setting is the Z ISO. This can easily be changed by navigating to Preferences>Mixer>EQ Type.

The buttons below the 8 knobs function as you might imagine and have full LED feedback.

FadersThe Faders across the bottom of the APC40 have pretty straight-forward action. Lets dive in.

Faders 1-4- Each of these have direct control over their respec-tive decks. Nothing unusual here.

Faders 5-6- These faders control the tempo fader for both decks A & B. When placed in the middle they send out the value 0%. Moving them up will lower the track tempo, and Mov-ing down will raise the tracks tempo.

Fader 7- This fader controls the Dry/Wet of the loop recorder. When SHIFT is pressed it will con-trol the loop length of the Loop Re-corder.

Fader 8- This single fader gives you control over the Monitor Mix. When SHIFT if pressed it will give you control over the Monitor Volume. Both of these controls use Soft Takeover so their shouldt be any erratic value changes.

Loop RecorderThe loop recorder is controlled using the three grey transport buttons above the crossfader. They function just like they are label. Play=Play/pause Stop=Stop & Delete Rec=Record. To pause a playing loop just press play. To delete the current loop press the Stop button.

Selecting PagesThe bottom four buttons represent the first four Track select but-tons on the APC40. When Hotcues is selected the buttons

above will func-tion as depicted in this example. The track select button will light up GREEN to show you what page you are cur-rently controlling.

HotcuesEach hotcue but-ton will light up RED initially. This means there is

not current hotcue set. Pressing a red (empty) hotcue will drop cue at the current playhead location. This will cause the button to light up GREEN. Once loaded the hotcue will function like a

normal hotcue. To delete a cue point simply hold down SHIFT and press the desired hotcue.

Deck ScrollingHolding down the Deck Scrolling button and turning the Cue level knob (also know as the browser scrolling knob) will allow you to scroll the playhead through the track just like you were turning the jog wheel. This doesnt allow for scratching, but is fantastic for seeking through music and setting new cue points. Releasing the deck scroll button sets the cue level knob back to controlling browser scrolling.

Flux ModeThis button toggles Traktors new Flux mode on and off. The button will light up YELLOW when off and GREEN when on.

The Loops page gives you control over the respective decks loop controls. These button plus the Auto Loop button will have you looping tracks in no time! Simply select a loop length by pressing the desired YELLOW button as shown in the picture below. Once selected the button will light up GREEN. Then sim-ply press the Auto Loop button to engage the loop. Pressing the Auto Loop button again will disengage the loop. If you want to set unusual sized loop thats easy too! While the track is playing press the Loop In button to drop a marker. This will be the begin-ning of your loop. Then press the Loop Out button to drop a marker for the end of your loop. This button will drop a marker and activate the loop at the same time. This kind of loop can be disengaged using the Loop Out button or by pressing the Auto Loop button.

Section 2

Loops Page

14

This section gives you the same functions as the fa-mous DJTT Instant Gratifica-tion Mapping. Once this page is selected simply hold down a button and you will hear the desired effect. Each effect and its value are written into the mapping, but can be changed with some basic mapping know-how. We will talk more about this later.

Try using this page on both decks at the same time for some ex-tra fun. Also, try turning the dedicated FX knobs while holding an I.G. button to change the FXs value in realtime. Remember, this value will reset every time the I.G. button is pressed.

Play- This button control the play function for the entire deck. Holding SHIFT and pressing play will activate the Decks Loop feature.

Loop Up&Down- These two button move the loop length selector up and down.

Sync- The sync but-ton functions just like Decks A&B. Holding SHIFT and pressing Sync with set the Deck as a master tempo source.

Playback Type- The second row of but-tons toggle each sam-

ple between loop and one-shot playback. They show solid yel-low for loops and flashing yellow for One-Shots.

Cap/Trigger/Mute- These buttons function just like the sample buttons on a S2 or S4. Pressing while the slot is empty will cap-ture a sample from the playing deck. The samples length will be the same as the loop length of the deck is being captured from. Once a sample is loaded, pressing the same button again will cause the loop to start playing. Pressing again while the sample is playing will mute the selected sample.

Holding SHIFT while pressing one of these buttons changes its functions to Stop/Delete/Load From List. Press while a clip is playing to actually stop the sample. Press again to delete the same from the slot. Pressing while a slot is empty will load a sample from the browser list instead of capturing from the track decks.

Track slection buttons 1&2 will cause the lower bank of knobs to control either FX1&2 or 3&4. The knobs work as depicted above. The eight buttons below the knobs function the same as what you see in the software.

Holding SHIFT and turning one of the Dry/wet Knobs will switch the FX unit between group and Single FX panel modes.

In group mode: Holding SHIFT and turning one of the FX knobs will allow you to scroll through and select a different effect.

In Single Mode: Holding SHIFT and turning just the first FX knob will scroll through all the single FX choices.

Midi MessagesHere is a figure that tells you what midi value is assigned to every control on the APC40. You are gonna need this...

When mapping LEDs in traktor (also known as OUT com-mands) you are going to need this. These codes only apply to the APC40.

Above you can use the chart to determine what each modifier value does. These modifier are the heart and soul of the colli-sion mapping. If you plan to edit or change any part of the map-ping i strongly suggest having a firm grasp of whats going on above.
