I keep getting an error when I attempt to create an audio-visual application in OF

Hello Everyone

I have recently been attempting to create an audio-visual application using the ofMaxim addon:

I keep getting these errors (I’m using a Windows PC):

RtApiAsio::getDeviceInfo: error (Hardware input or output is not present or available.) initializing driver (Focusrite USB ASIO).

RtApiAsio::getDeviceInfo: unable to load driver (ASIO Saffire).

Does anyone experienced in ofMaxim have advice regarding how to solve this?

Thanks

Harry
