It seems to me that all major brands, including Yamaha and Korg, have some quirky features that prevent their arrangers from becoming perfect.
Korg's weak point, for me, is the way it handles user styles. In roland or yamaha it is possible to connect a USB flash drive with thousands of styles and listen to them one by one, and use them directly . But Korg does not allow that as you must first load into the keyboard. So if you have thousands of styles on the USB drive, it is impossible to test the styles quickly in any Korg keyboards, including the high-end PA range.
About Yamaha, I wish they had some features like:
- The ability to change the chords in the Intro: I was told that in Korg, you can play any chords and the Intro will change accordingly, making the Intro refreshing.
- Smaller, portable and being able to power with batteries.
- The ability to change the chords after you have recorded the song. This feature is available in Korg's PA range. Basically after you have recorded your audio, you can easily check and change any chords. A quick look on YouTube will show us how.
Of couse, one may say 'Oh, but I don't like any of these features. It is perfectly fine now.' But perhaps you would agree that it would be nice, and therefore perfect, if features like these are added in ONE keyboard.
