I've bought software one time from M/F. It was the Arturia Oberheim Matrix 12V synth that was on a SDotD. The license key showed up the same day, but many hours later. I remember that the wait p'd me off.
Sure wish I could try that synth. It needs to be activated via ASC (the Arturia Software Center), which installs but refuses to run on my Dell XPS8500, a pretty run-of-the-mill PC.
In any case, I won't be buying software from them again. The only time I buy ANYTHING from them is either: a) a SDotD (got my Tascam US-16x08 for $199, for example!), or b) Sweetwater doesn't carry the product, and they do, and their price is competitive.
They're owned by Guitar Center. Since the discussion of politics is forbidden in this forum, I shall say no more. Other than...
