Yes, it was a disappointment, the Kn series was a fantastic keyboards.

1-The display came up and you could slant it if needed.
2-You were able to display what you wanted to see in the display. One display if you were recording. Another if you were playing live. It was programable.
3-I lay a chord track for a song I was going to sequence faster than my Pa4x.
4-If a wrong note was recorded in a song it could be easily changed. And not by finding the measure and counting to find where the note was. The Kn showed a music staff to make the change.
5-In creating a style you could select a Acc. track, an intro, or an ending from another style.
6-Writing in step time included length and velocity. (Emotion)
7-In creating a sequence you were able to change everything you wanted to change and put into one of the reg memories. Then place the change where you wanted it.
8-You were able to create a sequence and add photos. I took pictures of the condo I was to play in -- recorded in a sing-a-long with the pictures and displayed it on the house video screen while I was playing.

There is more, and there were set backs also. The reason I sold my Kn7000 was because it fell short when I played contemporary music. I added a sub-woofer and sent my drums to a separate channel of the mixer; this way I could add more of what was needed. OPINION – It was lacking in the same way a Yamaha is lacking against a Korg. I also feared the thought of repairing an aging keyboard.

Please keep in mind that the Kn7000 was created many years ago. Ahead of it’s time? Yes.

I often wonder why most of my recording and playing was when I owned a Technics. I’m betting it was because I did not spend so much time on technology.
