Please do not try to make a s910 sound like your Kn7000 – It will not happen, nor would it even come close.

THE SECRET:
Use the s910 as it is designed to be used.
Examples:
50’s S910
Glenn Miller Kn7000
Disco S910
All Big Band Kn7000

Because I have started playing out again I am looking for a used S910.
1-It is by far lighter
2-A built in Vocal Harmony
3-Plays Mps easily
4-Plays Midi Files easily with additional features.
5-The sound of the keyboard seems to blend to contemporary music.

1-For my important jobs I will use the Kn7000.
2-For my personal home use I will use the Kn7000
3-The sound of the Kn7000 is pure quality.
4-The composer and the Sequencer are superior.
5-And here’s the BIG ONE – I so enjoy playing it.
6-The second BIG ONE – The desire to play -- it makes me want to play pure beautiful music -–and it is so friendly.

Again, once more, this is only my opinion.

Have a great Christmas and a healthy New Year, John C.
