From the perspective of performance, depending on the hardware used, but in my setup, nothing to say, I'm not arrive has its limits.
I use it for about a year and this is my main instrument vst.
The sound library comes with is very good and makes a good start without having to jog immediately after the samples. The possibilities of this sampler are very varied and quite simple to be implemented.
In short, it's a pretty good tool comfortable to use.
The problem is not from my machine configuration. Soft slow. Interface ugly death. One must delve into the doc to master. Definitely not intuitive. Too bad for a sampler. I do not understand ergonomics, if a. Dcevantes performance. J'espre that the next version fixes this.
Not ergonomic at all. Soft really bad. Pay for its expensive option that is not accessible to a mouse click. Rtif software, can not be easily apprhender.
Repeat this choice, no.
