Mini Korg Patents - maybe

[Haible Juergen]

Hi!

I found something that looks like patents for the Korg 700 - at least
reading the 
abstracts reminded me of the Mini Korg I used to own.

The site is  

http://patent.womplex.ibm.com/advquery.html

and the patents are

3918342    -  V/Hz keyboard circuit

3821461    -  Traveller filter

(I simply typed in "Keio" in the text search)

I just read the abstracts. Anybody would like to dig deeper (i.e. get
the full texts) ?
