Using the WDM Driver or Generic Microsoft driver for that audio device will have much slower latency and performance than a native ASIO Device Driver. Thus when using ASIO4all you are bypassing the manufacturer's own ASIO Device Driver written specifically for that hardware. This means that ASIO4all connects to an audio device's own WDM Driver or the Windows Generic USB Driver and allows that driver to appear as ASIO to your DAW.
(Example Realtek or Nvidia HD Audio, SoundBlaster cards) The Focusrite Interfaces all come with a native device specific driver that includes both ASIO and WDM driver types.ĪSIO4all is designed for units that do not have native ASIO Device Drivers, like your computer's built in audio. We do not recommend using ASIO4all in your DAW for your Focusrite Interface.
