Hi,

GEM sk880/sk760 WK8/6 have excellent user style arranger:

1) you get 32 user styles which are ram-backed. So when you turn off the power, you do not lose them... (it is better to save them on disk just in case)

2) excellent arranger capabilities for very advanced styles

3) easy to use style arranger: play a note and it repeats over the whole phrase.
