Well damn!
It was a short-lived initiative back in the late 2000s. Some singles were released with bundled remixing software (very basic, mind you) and the stems of that single.
Some were lossless, some were lossy. And it had major compatibility issues with most OS's above XP. That's where Feeder's "Feeling A Moment" stems came from (those were lossless at 16bit 44100KHz). Robbie Williams' "Sin Sin Sin" + "Advertising Space" were lossy.
The "Umyx" exe also contained the raw stems inside it, so you could tell which one was lossy or lossless by looking at the size of the exe itself.
