The KN2400/2600 styles which you mention, are included in the Total download here : http://www.willumspages.co.uk/page8.html I believe they were converted by Alec, to KN7000 format.

All 'KN' files have unique identifier bytes at the start of the file, which determines on which instrument they can be used. I seem to remember Alec posting some time ago on this forum, that by using a Hex Editor, you could change these bytes and allow some files, not specifically intended for a particular 'KN' 'board, to become usable.....
Perhaps this was how the KN2400/2600 styles were 'converted' to make them compatible with the KN7000 ??

I tried a search for that topic on this forum, but drew a blank frown
