linux too (not too complicated)
Another solution to your problem:
Use one simple PC just for audio processing, and another simple pc for the other stuff, and a KWM switch.
Maybe sounds crazy, but it's a cheap and easy solution, and the other programs will not affect the sound
quality. So, you only have to click one button to switch between Centrafuse, and a very
basic windows or linux, with only sound processing and sound player apps running.
