Yes my friends this is the all new Roland arranger module. Here is the link:

PS: Somebody might have already posted the same link. I haven't read all the posts in this thread so this might be old hat. Anyway, I'm quite thrilled about this new arranger module from Roland. There are 400 high quality Styles plus the ability to play and manipulate audio files. 128 note polyphony as well.

All the best,
Mike
