I am pretty sure that most of us would like to add drums to our song in Scaler 3. But, at this moment this is not posible.
Not possible? Really? Not as easy as adding melody, bass or rhythm, but with some tweaking, it is feasable.
Jeffy G. shows how this can be done. Watch his video to learn more.
I use a method relatively similar to his method # 2, but much easier for me.
I create a rhythm track in Arrange page, take any rhythm pattern, add Jamstix as instrument, select groove, kit, drummer etc. and leave to Jamstix to do what it can do the best.
Why rhythm (until the drum track will be available) and not a pattern in, for example, Addictive Drums, which I also have? Because any Scaler 3 pattern follows the Main Track. 
And Jamstix will follow the Main track, too. The patterns in other software cannot do this.
Maybe I’ll prepare a short tutorial if somebody is interested.
