I have a Soundblaster XFI, most will laugh at it. But it has a Asio driver that works very well and you can setup Asio Latency as milliseconds, i have mine at 8ms. I had a USB Focusrite, and it did really everything but doing a good asio latency. Still using slots in a pc to me is better then any usb driver of asio or hardware. Somehow with Cubase you must have luck and have a systems that works. But the midi latency should be below at least 10ms. And with C9 and Maudio Oxygen61, a simple soundblaster as a card in a slot, pretty cheap, but all whats needed is SSD, processorpower and low asio latency.
