Hey! Sorry about this. You may be able to get the refund via this link.
That being said, I may add the ability to capture ASIO inputs in the future but depending on your setup that may not be sufficient. I believe the limitations with ASIO are that I cannot capture system or individual application audio when it is used with ASIO. ASIO connects directly from the application to the soundcard. I do include a VST plugin that routes the audio from your application to MiniMeters. That was added so it could be used with ASIO drivers. Is that not sufficient for your use case? I'd love to help make MiniMeters work more for your setup in the future.
