MuTools - Enjoy Making Music


Read This


The MuLab zip packages below contain all of MuLab.
Without a user key MuLab runs in Free mode, by inserting a user key MuLab switches to UL mode.
For the differences between MuLab Free and MuLab UL, click here.

When you cross the limits of MuLab Free, you'll regularly hear a soft noise.

MuLab UL user keys can be purchased in the MuTools Shop.




  MuLab 6.5.46 for Mac OSX

  MuLab 6.5.46 for Windows (32 bit)

  MuLab 6.5.46 for Windows (64 bit)

If you're not sure whether to take the 32 bit or 64 bit version, take the 32 bit version as that one will also work on 64 bit systems.

Change Log           M6.5.46 App Patch




Download the MuLab zip package and unzip it to a new folder on your harddisk or USB device. After you have installed the MuLab package, double-click the MuLab application file to launch it.

MuLab comes as a portable and self-containing folder. It does not install anything on your system outside this folder. You can move the MuLab folder after you have installed it. You can even put it on a USB stick and carry your MuLab with you.


 On OSX if you get the alert "MuLab can't be opened because it is from an unidentified developer", then control-click or right-click the icon and choose "Open". More info on OSX GateKeeper on this page.


 On Windows 7/8, it may be better not to install the Mulab folder under the 'Program Files' folder, but rather in a non UAC protected folder like C:\Applications\Music\Mulab. This is to avoid access problems caused by Windows' UAC mechanism. Alternatively you could try to run MuLab with "Run as administrator". To do so right-click the MuLab exe file.

If you have Microsoft SmartScreen enabled, choose "More Info" + "Run Anyway".


For all details on installation, inserting your MuLab User Key, updating etc, see this doc page.
