This is what I am trying to say all the time you can use it for other things than painting soundscapes or importing pictures. Here he is using the voice but it can be with any instrument. As got mentioned before in older posts one idea is that you can start to build up a library of sounds that you can paint with or drop into the canvas like samples in tonalities and rhythmic placement.
You also now have layers (in difference from the first version) so you can build up choirs, different forms of instrumentations etc directly with the microphone on your device. One thing that is very good to is that it works like a multitrack recorder meaning that you can hear what you are playing while you are recording all being on a separate layer if you choose a new layer first it easy to do coherent pieces of recorded music without any workarounds. Again... amazing! Still can not believe that so far it under five hundred persons that have downloaded one of the most or would I dare to say the most innovative and exciting application for Android!
