DX plugs (Sonitus) are turned off by default.
Here is how to enable DX plugs:
Edit "Sam_X64.ini". (located in "C:\ProgramData\MAGIX\Samplitude Pro X3 Suite")
Insert this line under [setup]:
NoDirectXInit=0
It should look like this when you are done:
[Setup]
NoDirectXInit=0
NoASIOBoost=1
MidiInDontUseSysex=1
/***********************************************/
Don't forget to add the dx folder path: "C:\Program Files\Cakewalk\Shared Plugins"
The Sonitus compressor and gate do not work because of the incompatible method of sidechaining that Cakewalk implemented.
