1) Ketron I Rate it with a 9 (For Audio Style Modeling)
2) Korg I Rate it with a 9 (For many advanced edit function)
3) Yamaha I Rate it with a 4 (very poor editing and very difficult to create a style from scratch)..
For Roland I don't have opinion because I don't have any model..
Makes me womder wa edit functions you found on Korg ot available on Ketron..
- the only one i can think off, is not being able to edit GM voices on Ketron..
But thats not a style thing...
- and then there is the 4 differend variations for different chord types in Korg..
I found that there are so many little hidden things and settings on the SD9 pro its even beyound what Korg allows... and thats not just audio tracks... espescially the whole style modseling tab on the sd9 pro... and the launchpads... make ketron stand out.. but also options tos set a single drumset and bass troughout a performance..
