The nice feature on Qranger is also to use it for play standard midifiles/audiofile BUT with included up to 32 markers pointer: http://www.lionstracs.com/demo/qranger/Qrangermarkers.jpg

in this way you can LOOP some parts of the midifile/audio/mp3 like in one arranger system.

After we have loaded one media file on the session, we can just add the marker pointer where we like and save the session.
The Mediastation qranger engine will reload the same session like a normally styles, BUT under this way will be alble only to jump to the 32 markers, global transpose and global BPM change.
This is also a nice DJ GROOVE BOX features that a lot of DJ ask us, just for import some Mp3 files and loops the parts how they like.

With this features believe me that playing normally midistyles will be really so boring, the problem is that your keyboards there can not offer this features and then you have to use forever the styles only.
Pity..but maybe someday they will add this amazing features too.
enjoy what you play
