Milky Tracker. Did try it a long time ago and found it... and having SunVox why bother with something that is so much more limited... first of all it has no internal sound generators, but then again it could be something to check out if you want a sample player that have a some interesting tricks up its sleeve. If you can get used to the tracker way of thinking.
Lucky me when I got my first smartphone SunVox was one of the few applications that was possible to use in a more serious way so I got into it because of this and after using it for a while found it not like I thought in the beginning a stupid way of working and that a piano roll sequencer was so much easier... found out that the tracker way is a good, fast way as soon as you get over the initial hump. The first thing you will complain about mentally is that there is no easy way to polyphonically do chords etc as in a piano roll but as the lanes are laid out side by side it is not that hard to program in the extra notes and actually many times faster plus the control you have is unsurpassed compared to a traditional piano roll sequencer / DAW. Nightradio was also very smart to have incorporated a piano keyboard in the interface that you can use to program the notes and play them from so that makes the transition easier and in general more user friendly.
If for example Caustic had worked on that phone probably would never got into trackers the way I have done and now I fly happily in between both ways of working depending on what is meant to be achieved.
But to finish this post I quote from Computer music magazine calling SunVox:
Esoteric and hip - I do agree about it being esoteric as it always had this veil of mystery to it for me.
