Well, it looks like Traktor Pro 3 runs fine on a Windows 7 i3 laptop, even though they spec an i5 as a minimum. This could be because I'm not a heavy FX person.
One monster of an install though - you wonder when it's going to finish!!
First impression - the GUI looks nice, but has the "flat" look that seems to be in vogue now. Waveform looks good. However, no "Smart Playlist" implementation in the Library - last time I checked my calendar it was 2019 - they are still way behind with this. While perhaps less an issue for (barf, puke, throw-up) iTunes users, a shortcoming like this often will cause CEUS to manifest itself in hardcore Traktor users - Constant Equipment Update Syndrome.
