Just pretend it's only three zones--which would not have been a disappointing answer to the how many zones question--and you won't be disappointed by the lack of a fourth fader. ;-)
OK, so I pretend :
- The PX5S has half-pedalling and expression input
- The CP480 has no looping
- The Kurzweil Artis has string resonance and half pedaling for the internal AP sound
- The Physis Piano has coating on the black keys instead of a clean plastic surface
- Nord, Kurzweils and new ES100 have 3 sensor keybeds
- ...
Just making fun, but if I'd have to pretend away everything that strikes me as odd or missing , the perfect board could have been a Casio Tone two or three decades ago ;-) Sometimes I just fail to understand the decisions that are made dusting product development. Can imagine Yamaha R&D:
- Let's make a stage piano with four zones
- Yeh ! Good idea; let's give it four faders then
- No no no no, too expensive (says guy in suit); two faders thats more than enough !
- Ah...come on... give us the faders - we need them
- Ok ok ok, we'll give you three; but that's the max we can do. Otherwise we go bankrupt and the CP production cost will soar (an extra $ 3 dollar cents).
- Deal, compromise, we'll sell it to the people with a good marketing story about how you can use a switch (?) to go from layer 1~2 to 3~4 for fader control...or something
It will be great anyway. It will sell anyway. I'd perhaps buy it anyway. But IMHO it's OK to point out some striking details of a new product , even from the limited info we have have available until now. Or 'pretend' it away, we'll see...
