No ordinary Yamaha or Roland or Korg styles will play on it. Same as with any other module. Why one might consider using it:
Compared to i.e. a PSR S7701. MANY more effects
2. 4 lead voices each harmonizeble individually to a different harmony type simultaneously
3. 8 variations
4. 8 fills
5. 8 OTS's
6. 2 breaks
7. Round robin drums like on the Genos
8. Humanized played lead notes (similar to round robin drums but applied to what you play with the lead voices) that includes i.e. decent guitar strumming
9. Style immediate reset
10. Half bar fills
11. Extremely advanced editing capability
12. Intelligent transpose splitpoint that follows where you play your chords and lowers/raises the splitpoint accordingly
13. Also uses registrations
14. You can bind any Yamaha or any other midi transmittable outputs to soft inputs
15. Store pre-setup effects in memory to use in any other place
16. Instantly select a part from another track to play in current variation whilst playing live
17. ONLY connection to Yamaha single USB cable
18. Touchscreen that can also facilitate a mouse
19. Current OTS plays out in FULL in the background whilst new OTS kicks in
20.
This is the only place I will update demos of what I am personally able to achieve with it as a user.
21. Pitch or octave shift ANY accompany part even on the fly - listen to the choir voices in my demos
...To name but a few of the improvements over the standard older Yamaha's. The list above are only the ones that I've discovered and can understand. The manual states many more that are currently beyond my grasp or direct needs.
And because it's software driven, the sky is the limit to whatever they choose to ad to it in future WITHOUT you having to change your arranger every time. And there is the user memory on the arranger itself for any newer voices that might be required as an later upgrade (I will not be surprised should they pursue this route in future). Heck, I've already added voices from the GHENOS pack to it & I'm only a novice...
