I have the MODX 8 and I'm still very satisfied even though I'll be selling it soon. The first thing I did was connect both the MODX 8 and the MODX M8 and I have to say that it's a step forward considering that the M8 has double the sounds of the classic montage. Both in terms of the 88-key keyboard and the quality of the sounds, which are fabulous. I've only listened with headphones for now, I'll soon try both in the PA system, but I predict that it will be fantastic, a beautiful instrument, a little more compact than the classic MODX but very beautiful.
