great way of working, I do the same, its important to get the frame built before creativity is lost at the slightest.
though over working a song will yield a better version, I cant deny this in all my years, I re-work songs a lot.
till they're right.
but what your doing is great and a lot along the lines the way I do it too.
same here, hardly a glitch, always know what to expect, never sitting there like "what was that ?"
feel bad for those with troubles though, hope they have better luck.
a lot to be said for a clean install with no bloatware pre-installed.
