Yup, only runs in Windows as far as i know, and I don't think the program has been much updated since Windows NT, to give you an idea how light and simplistic it is. Don't expect much, it's outdated, crude, almost laughable!
I'm a sucker for those things from digital era CIRCA 'when it wasn't quite there yet', like how quickly we go through phases of new digital products and software without looking back. There isn't yet much of a 'vintage' phenomenon with those things, compared to actual instruments or hardware. The reason being pretty simple, in that department, new is pretty much always better...
But then I don't know, personally I like to try and expand or bend the intended purpose of these things. How easily accessible and understandable they are, yet as soon as something new pops up we toss them aside. Put simply, working within a tight framework without all the malleability and options of the new stuff excites creativity, ingenuity, resourcefulness, etc. Major downside being the amount of f*cking around needed to get where you wanna go.
I'm sure someday, when I have a clue what I'm doing, I'll be able to merge the two aspects...
