I actually ended up selling a Take 5 because it wasn't the more refined X4 that I hoped it would be. Having owned several Mophos along with a Tetra over the years but sold them after getting frustrated trying to program them, there was something about their sharp, gritty and almost lo-fi character that really appealed to me.
The Take 5 is a well specified and capable machine and sounded really good but to me just didn't have the clarity, presence and grit of the X4. It was almost too smooth and sounded like it had all the rough edges of the sound filtered out.
It comes down to what sound character you want and I ended up with an X4 which I love so much more than the Take 5. It just sounds more alive and in some ways vintage. Almost Korg-like, whereas the Take 5 is Rolandy.
