What's new in this version:
Version 2.0.16 added feature to add videos to instant sounds/videos.
Pros: Easy to setup and use anytime, Customer Service is very good, There's a Key changer, you can speed up or slow down music without changing key,
Cons: Recording Sound isn't that great but maybe I need a better Mic or Computer,
I personally have 4 products from powerKaraoke and there all great to me. Mind you, I'm talking about Practice, this is not a professional music studio but for the karaoke singer who likes to practice his/her songs before going out and doing it live!
As I tried to get the balance right between the vocals and the music it (which I gave up on in the end) as I went from the set up screens back to the player or minimised to look at anything else it regularly locked up (graphics issue I presume).
