Can I use the V7 and NS7/FX with the ITCH for NS6 software version?

ITCH for NS6 was created and tested specifically to support the NS6 Controller. It is not intended to be used with other controllers. Note that multiple versions of ITCH can be installed side by side on the same computer.



It appears that ITCH is not recognizing the NS6 hardware. The software states hardware disconnected in the single deck player. I installed fresh using the disc that came with my NS6. What should I do?

  1. If you are using a Macintosh:
    1. Disconnect the USB cable from the NS6.
    2. Insert the Itch for NS6 installation disc.
    3. On the installation disk, Control+click ITCH for Numark Installer.mpkg and choose Show Package Contents.
    4. In the window that opens, navigate to Contents > Packages.
    5. Double-click Numark_NS6_midi.pkg to install the MIDI driver. The installer will force you restart when complete.
    6. Relaunch ITCH for NS6. The NS6 should now be recognized.
    If NO...
  2. Is the USB LED ON in the middle of NS6?
    If NO...
    1. Remove the USB cable. Turn off the NS6, wait 5 seconds, then turn it back on. Wait 5 more seconds, then reattach the USB cable. Relaunch the ITCH software.
    2. The driver may not have installed properly (this is very rare). Try running the installer disc again to repair the drivers. Make sure you restart your computer after the reinstallation.
    If YES, move on...
  3. Does the Numark NS6 USB Audio Panel state that it's connected?
    If NO...
    1. Reinstall using ITCH Disc (as above). Also try a second USB cable or USB port on your Computer.
    If YES, move on...
  4. On the Macintosh, open the Audio MIDI Setup utility, and view the Audio tab. Check that a Numark USB Audio Device is present in the audio device list on the left side.
    If NO...
    1. Reinstall using ITCH Disc (as above). Also try a second USB cable or USB port on your Computer.
    If YES, move on...
  5. On the Macintosh, open the Audio MIDI Setup utility. View the MIDI tab. Is a Numark USB Audio Device device present and highlighted in MIDI Window?
    If NO...
    1. Check for a non-highlighted Numark USB Audio Device.
    2. Disconnect the USB cable from the NS6. Click the device icon to select it.
    3. Click Remove Device option above.
    4. Then reconnect USB and see if the device reappears in the MIDI window.
    5. If so. Launch ITCH again, and check its status. If not, Run the ITCH installer Disk again to reinstall drivers. Restart the computer when finished.
    If YES - move on...
    For a case where all above steps returned a YES answer, perform the following: (note, this is a one time process):
    1. Connect the NS6 to the computer, and verify that USB LED is lit.
    2. Download and install the free Mac OSX utility MIDI Monitor.
    3. Then launch the MIDI Monitor application.
    4. Open Sources and make sure MIDI sources is checked. (this should happen by default)
    5. Press buttons, move faders and turn platters on the NS6. You should see data sent from the NS6 to the MIDI monitor window indicating correct communication with the computer.
    6. Close MIDI Monitor.
    7. Open ITCH for NS6. The controller should now be recognized.


Why is my Cross Fader functioning the opposite of my Crossfader Assign switches on the front of the NS6?

This can occur if you have run older versions of ITCH for NS7 or V7 controllers. Those older versions have a soft setting in the Setup menu to Reverse the crossfader. If this was checked in the older version, that background setting may have been adopted by the newly installed NS6 version. To cure this permanently, open the older version and change the setting to normal. Or, simply use the opposite settings for the NS6 assign switches. This will not affect stability or crossfader performance.


Why are the platters touch so sensitive after first booting the hardware/software?

The NS6 features intelligent platters that continually calibrate themselves to the user and to their environment as long as it is powered on.

Temperature and humidity vary from venue to venue, and also throughout the night.  To provide the best possible touch response and feel in varying environments, the NS6 continually calibrates the capacitive touch-sensitive platters as you work.

Initial calibration is quick and easy, though not required:

  • Prior to beginning a set and after power on, deliberately touch both platters in several different places.
    This allows the NS6 to calibrate to your touch, and ensures that platter sensitivity is just right (i.e. not too sensitive).

    Note: It doesn't matter whether the ITCH application is running, but the NS6 must be powered on for the intelligent firmware to be active.
    Note: The NS6 will recalibrate every time you touch the wheel, so if you don't touch upon power on it's ok, just remember to touch when you load up and cue your first song of the set.


Why do the platters suddenly stop responding to touch in Scratch mode?

Check to make sure your NS6 is on a solid surface. Surfaces like thick carpeting may cause the touch circuit to become less sensitive.


The SKIP function is not working. What should I do?

SKIP requires BEAT GRID setting to be ON, since it needs a grid reference in order to stay in tempo. Engage BEAT GRID in the Setup menu.


The AUTO Loop function is not working. What should I do?

AUTO Loops requires a BPM to be present on the song being played. Check to see if the track on deck has a set BPM. It not, you can use the TAP function to enter one quickly.


Does ITCH for NS6 feature the Instant Doubles function found in the NS7 and V7 version?

Because of the complexities of a 4 Deck solution, the Instant Doubles feature is not offered in the ITCH for NS6 version of the software. At this time. Stay tuned.


No audio is being played out of ITCH. The waveforms are moving, but are grayed out. What should I do?

Out of the box, the PC/Line switches above each line fader are set to Line/Phono for external instruments. Simply toggle these switches to PC and the audio will pass form ITCH software (with colored waveforms).


Other tips and tricks

I use Virtual DJ. What scratch sensitivity should I set when using the NS6?

We recommend setting the Scratch Sensitivity to 50% when using Virtual DJ with the NS6.


Updates and Support

How do I update to the latest NS6 Firmware?

The first NS6 units will ship with firmware version 1.07. While this version is very stable, by the time of release, a new firmware version (v1.13) will be available which improves the functionality of the LED lights on the controller. Customers can update to this latest firmware right within ITCH 1.8.

  1. Launch ITCH for NS6.
  2. Select the Setup menu and choose the Hardware tab. This window will indicate that a newer firmware version is available.
  3. Follow the prompts.
  4. After the update process is completed, Restart ITCH and power Cycle NS6.
