Okay, now I see it -- one little paragraph at the bottom of page 33 does mention the style revoicing, and I did miss that. You'd still think they'd go into more detail about how to implement that feature in the main manual. And when going to the section on registrations, for what is stored related to styles, this is what it says:
Style settings: Style number, ACMP on/off, Style vol-
ume, Track on/off, Main section A/B, Tempo, Fingering
type, Smart chord key
Nothing about style revoicing or instrumentation. But it's good to see such a feature on these keyboards.
I wonder if you'll be able to tell the E473/EW425 whether to save a style in a registration or not. And I'm not talking about the freeze function, but it is similar. On the previous keyboards, if you hit the "song" button before setting up and saving a registration, then you will not save any style data to the registration, which is how to implement a freeze on keyboards such as my E433. Since no style data is saved to the registration, then the currently-playing style will not be changed when that registration is called up.
The freeze function on the E473/EW425 accomplishes that, but with the revoicing options, it might still be nice to have this ability to apply this sort of freeze to individual registrations. Why? Well, let's say you set up a few registrations with custom revoiced styles -- remember that revoiced styles will not be memorized in the keyboard unless you save them to a registration. If you want to recall those revoiced styles, then obviously, you need to have style-freeze turned off when calling up the registrations with your custom styles. But now, with style-freeze turned off, if you want to call up other registrations to change the sound while playing those custom styles, then the concern is that calling up those other registrations for the sounds, will also call up the style information stored in those registrations, which would then stop your custom style from playing. Whereas if you can tell the other registrations (the ones where you only want voice information) to not save style data (like what can be done on the older models), then you can have a few registrations with your custom revoiced styles to use to call up those styles, and then call up just voice settings with the other registrations while using your custom styles.
Otherwise, to accomplish this, you'd have to have style-freeze turned off to call up the registrations with your custom styles, and then turn on style-freeze before you start playing a song -- and then do the same thing again every time you want to use another registration with a custom revoiced style.
