As soon as there is time I will have to write my own review as it is a interesting approach and the sound is very good.
It almost feels like cheating doing music with it as it is hard if you set it up right to do anything that sounds bad but do not get me wrong it is not one of those loop / sample put together by number applications it is truly your creations in the end and think that it has a lot of possibilities to push it and make some unique and great grooves with it.
Highly recommendable and it is still a 50% of as a introductory price!
