Gunnar's right, as usual. If you don't have a sx6 hard drive, you won't know what we are talking about.

If you have the sx6 hard drive you can convert midi files with lyrics to TLX (technics file format) lyrics which come up full screen with large programmable fonts, a better lyrics screen than the standard view you get from the normal sequencer lyrics screen in the 6000/6500. Also works on upgraded 5000 hard drives, I believe.
