And here is my cherry-pick of features that others here have already posted (apologies for not individually crediting each poster):

Quote:
to be able to hook up an ipad or laptop and use apps like unreal book to pull up the lead sheet and set up the keyboard all at once.

to be able to do more globally such as increase the drum volume across the board. (a Part Global Offset?)

The ability to select any voice in the keyboard and place it with the Style's OTS settings without first going to the Style Creator Program first and creating a user style.

An auxiliary, stereo input that has it's own, independent volume adjustment, slider or electronic--either is fine. (and maybe it's own dedicated MFX section or Master Tools MFX)

more assignable options to the sliders and the wheels. Everytthing should be assignable.

- a couple or 4 assignable buttons for you to customize per your choice

fix the sliders so they do not "jump" in and out when you first move them. makes using them frustrating and can produce huge unexpected variations in track volumes. [perhaps set it so that POSITIVE direction adds to the preset value, and scaled so that whatever amount of travel is available is used to go from the preset value to the max available, and NEGATIVE the reverse]

Dedicated Bass Inversion button on the console

I'm surprised that Yamaha keyboards still don't have a style restart button. It's still hard to insert a 3/4 or 2/4 measure into a 4/4 song.

2. Touch Screen (Large)
3. The ability to load Akai Samples
8. Simple style backing so that those that wish to play with their left hand can, rather than having to always play along with the style. (My pet hate with all Yamaha styles (See Roland for how to do it)
9. Advanced editing options for styles and sounds (And I mean advanced) similar to workstations. (Could be an option)
10. Comprehensive Midi Controller options

3. Trio Button - I would love to have a ONE press button that would drop out all other style parts instantly except Left hand, Drums, Bass.
4. Pianist Button - Similar to the Ketron Audya a ONE press button that puts the keyboard in Piano mode.
7. More Contemporary Jazz, Country, Latin Styles - These are becoming HUGE music genre's right now and I need MORE!!!!
8. Better Harmonizer - Almost there, current model falls short of TC Helicon quality.

Big 12,1" touchscreen
- Better and more advanced style edditing
- More indepth sound edditing (Motif sound engine)
- Sounds playable directly from SSD, with a user upgradable SSD up to 256GB
- Step sequencer
- lighweight but very durable casing (titanium)
- touch pad for X-Y controll
- D-Beam
- Vector joystick and integration
- Ribbon controller


All GREAT suggestions that would definitely make me want a Yamaha more than I do right now!
