Mike:

let's take it step by step.

The key fact is plainly stated in 4.12 namely that you can load midi files as nx technics sequences, save them as technics sequencer files and the lyrics play back fine from technics files.

we have only just discussed here how lyrics can be added to midi files using a variety of external programs.

by now we should know it is possible to save sequences as midi files because this has already been described in 3.39; therefore it should be possible to save a midi file from the kn sequencer, add lyrics in an external program, then load and save as a technics sequence again.
