Think Logically


Start experiencing the power and ease of use that Z-Maestro has to offer. When you first download, you will have the Lite version of Z-Maestro. If you choose to buy the Pro version, you can activate the copy of Z-Maestro Lite already installed. Buying the Pro version once also gives you all future versions of Z-Maestro Pro.

The only change made is to the DirectSound driver. An implementation of new_fluid_audio_driver2 was added to the DirectSound code.
