I installed Garritan CFX Lite on my wife's computer - Windows 10, 32 GB RAM. I registered the product and loaded the default sound set. The audio is set to use Realtek ASIO (the motherboard's sound chip is Realtek, and it's the default Windows sound setting). I get no sound when clicking on the virtual keyboard and no sound when playing the connected MIDI keyboard.

This is frustrating. Any one know what the problem is, and how to fix it?
