Where can you download the software?

You can download the latest version of the software installers from the links below:


You can download the last version of MediaMaster 5 here:


You can download the last version of MediaMaster 4 here:


Please know that MediaMaster 4 & 5 are no longer under development and so there will not be a more recent version than this one. We, therefore, advise all users with recent hardware and operating systems to upgrade to the current version, MediaMaster 6.

What are the limitations of the demo version?

First it's important to know that there aren't different installers for the demo version and the full version. The installer that you can download from our web site to try the software is the same as the one for the full version.


When you first install the software on your computer and until you activate it with a valid serial it will run in "Demo mode": you can use all effects, add as many visuals as you wish, connect and use any controller, setup any display configuration and there is no time limitation (the "Demo mode" does not expire).


In addition to this, when running MediaMaster in "Demo mode", you can chose to try either the "Simple Mode" (MediaMaster Express and Pro) or the "Fixture Mode" (MediaMaster Pro only).


In GrandVJ 2 there is an option in the Preferences allowing you to restart the software in GrandVJ XT demo mode so you can try it with the Video Mapper.


The only limitations are that you can't save your work and a 'DEMO' banner appears randomly on top of the visuals on the output and preview.

We always provide "'full" software installers, limitations from the "Demo mode" are removed when you activate the software with a with a valid serial number (and thus, concerning MediaMaster, you will be limited to the "Simple Mode" if you activate it with a MediaMaster Express serial).

In any case, you do not need to download another "full" software installer (except if there is a newer version available, of course) after you have bought a license.

Where is the user manual for ArKaos when the software is installed on my computer?

The manual is in Adobe Acrobat .pdf format and is included in the software installer. Once the software is installed on your computer, you can find the manual in the "Documentation" folder into your ArKaos software installation folder on your hard drive.


Be sure to also read the Release Notes PDF document which is in the same folder; while the user manual describes the software until the current major version (i.e. version X), the Release Notes document describes the changes between the major version and the latest intermediate version (i.e. version X.X.X).


Unless you selected a different path when you installed the software, the installer will create the software folder in:


  • On a PC:     C:\Program Files\
  • On a Mac:   Macintosh HD : Applications


Your second option will be to open the Manuel directly from the application ( Grand Vj or Media master ). By clicking into the help Tab , you will find the documentation shortcut . This shortcut will open the documentation PDF .

Can I install my ArKaos software on an external, removable disk

It is strongly recommended not to do so because the software generates a particular Machine ID code based on hardware information from the computer which runs it and the serial number allowing you to use the software without limitations is based on that Machine ID code.

In other words, you will need a new serial number each time you plug your removable hard drive in a computer.

Does my license work for Mac and PC

Yes, the serial generated corresponds to the computer's Machine ID, no matter what the system is. You just have to download and install the right version for your operating system, take note of the computer's Machine ID code and use it to generate a new serial number.

Installing the License Dongle Drivers Under macOS 10.13 and later

Apple introduced a new security mechanism in macOS 10.13 that requires a user’s approval before loading third-party kernel extensions (kexts). Installation of Sentinel Run-time Environment is impacted by this security mechanism.


When installing the License Dongle Driver on a new macOS 10.13 machine, you may receive an alert message “**System Extension Blocked**” as seen in the image below. This message does not occur if the operating system was upgraded from an earlier version and the License Dongle Driver had been previously installed.



Click **OK**. To complete the installation, proceed to **Security & Privacy** (as described below) in order to approve the kernel extension.


**Important**: Once you click **OK**, you have 30 minutes to approve the software.


**To approve installation of the Run-time Environment:**


     1. Click the Apple icon.

     2. Open **System Preferences**.

     3. Go to **Security & Privacy**.

     4. Click the **Allow** button displayed next to the blocked software.

Note: If you are not able to click the Allow button, you need to unlock the pane. Click the lock icon at the bottom of the pane, and then enter your admin password



     5. To complete the process, restart your computer.


**Troubleshooting**

If the blocked "System software..." is not listed on the **General** pane of the **Security & Privacy** screen, Gemalto recommends that you reinstall the Run-time Environment, and then immediately proceed with the steps 1 to 5 above.

Are the software upgrades free ?


#### Minor software updates

We frequently release free software updates to fix software bugs, add new MIDI controller templates or even some new features, these are called “minor updates”. To benefit from these updates, no license upgrade is involved; you just have to download the new software installer from our web site and install it on your computer, it will use your previous registration information.


#### Major software updates

When we release a “major update” with important changes such as a new software interface, new advanced features or extensions we generally charge for an upgrade fee to fund development and require that you get new license codes from your customer account to unlock the new version.


It works the same way if you want to upgrade to a superior license version such as from GrandVJ to GrandVJ XT or from MediaMaster Express to MediaMaster Pro; you have to get a new code to to have access to the extended features of the software.

Enttec USB DMX PRO

The Enttec USB DMX PRO is supported on Windows and Mac platforms.
For Windows you don't have to do anything special.
For Mac OSX 10.11 or above you need a special extension D2xxHelper. You can download that helper here:
http://www.ftdichip.com/Drivers/D2XX/MacOSX/D2xxHelper_v2.0.0.pkg
After installation you need to reboot your machine. It should now appear in Preferences -> DMX -> DMX Interface.

Know that the Enttec USB DMX PRO Mk2 is not supported by MediaMaster.

LED Mapper workflow example

A workflow that is used by some light designer is to create a mapping background in photoshop.
By example if you need to map a few bar you create a visual such as this one

The size should be as small as possible depending your fixtures, here it's in 64 by 64.
You must also use that in the LED Mapper:

You can then import your visual

You will see that in the canvas

You can then place your bars in the canvas

You can now rework the background picture you loaded in the LED Mapper with photoshop and changed the color as you want.
Once you created a few pictures you can load them in the MediaMaster library and map them in the theater mode by example

We have color rotation effects that should give nice results when mapped over LEDs.
