I've found that if I sell a keyboard while it's still current, I can get most or all of my money back. I don't change just for the sake of change. Well maybe sometimes I do! But I am just totally amazed that they keep getting better and better.
Here's what I would like:
As light a weight as possible.
The sounds, particularly drums, and styles of Roland and/or Ketron.
An easy to use operating system that lets you have access to various lead sounds easily.
Capability to load lyrics, mp3s, and midi files.
Easy external data access.
Organ style key touch (although G70 was nice too.)
Great vocal harmonizer like G70.
Joystick.
Big display and lighted buttons like Tyros 2.
Dependability and quality of construction.
Believe it or not, right now the Ketron Midjay seems to offer more of these features than anything else.
It's not perfect at anything, but it does a lot of stuff pretty well. Sorta like me!
