Interface does not offer to many options and i think this tool is good especially if you are new and try to learn how to mix or apply DJ effects to your song(s).
Set different loops to start over song at a desired interval, set different points (shortcuts) of exact time in a song and when you are pressing the melody starts immediately from that point. Make multiple points and press play for each of them and you will get good DJ mixing results.
Pros:- clean and very easy interface
- good for beginners
