In Mixcraft 7, click on the File menu, select Preferences and then Manage Plug-Ins. Remove the check mark next to any plug-in that you don't want to load.
Mixcraft 6 has two files, which you can edit to exclude effects from loading. In Mixcraft 6, they are located here: C:\ProgramData\Acoustica\Mixcraft
For older versions of Mixcraft, these files are located in your Mixcraft directory, for example C:\Program Files\Acoustica Mixcraft 5
DXIgnore.ini - DirectX effect ignore list
VSTIgnore.ini - VST effect ignore list
Simply open or double click the file with a text editor like notepad or wordpad and add all or part of the name of the effect. For example, if you had an effect called "Digital Media StudioDenoiser" that you didn"t want the software to load, you would enter:
Digital Media StudioDenoiser
You can also enter part of a name as a "wildcard." For example, if you entered the following, all effects that started with the word "Digital" would not load:
In a similar fashion, if you just entered the letter "D" then all the effects that start with D would not load, so be careful.
Enter each effect name that you want to ignore on a separate line. Finally, save the file and restart Mixcraft.
