As Microsoft ended security updates and technical support for Windows 7 in January 2020 and for Windows 8.1 in January 2023, please be aware that the ASIO driver for Saturn Interfaces only works on Windows 10 or later versions.
For more information, please visit Microsoft's website here.

SATURN (I & II) and ORBIT (1 & 2) will require ASIO drivers on Windows (Win10/Win11) to ensure seamless operation with your computer. Follow the instructions below to complete the installation:

*Please ensure you plug the USB cable of SATURN (I & II) or ORBIT (1 & 2) into your computer only after the ASIO driver has been installed.

Once everything is set up, you can also launch the Carver Pro control panel by clicking on the Carver Pro icon on the taskbar to adjust the bit-rate, buffer size, and even enable Safe mode to prevent audio issues or artifacts.
