It seems that Button positioning on the SD1 is somewhat of an issue with a few folks . However , under the utility mode you can change from Numeric or Group . Alowing you to use the keypad vs. the Fucntion buttons to choose styles .
ONE TOUCH SETTINGS allow you to choose 80 tones which can be accessed quickly . This feature does not just limit you to solo voices . You can even save programs (patches/4 layered sounds) iwthin the ONE TOUCH .
I think the layout of the intro/ending fills variations etc buttons is the best yet for KETRON .
The way KEtron uses the hard drive is also very important to note . Record directly to hard drive . Edit midi sequences from the hard drive . Many cool features !
