Thanks for the clarification. .. I should have thought that not everything is so simple. 
In the Ketron manual it is written that the file with the Ketron style markers simply has to be saved as a standard midi in format 0 and get .KST extension. After that it is supposed to be ready to use in the Ketron device.
It is possible that the new Ketron SD series contains built-in logic as to how the midi notes are to be interpreted. Then this logic has to be built up in Varranger, which is probably not that easy.
But this would be a bomb if implemented in Varranger ..
