Fancy arrangements meant for karaoke playback typically contain very many notes that nobody really wants to read. The OP sometimes posts such arrangements as MIDI files. It would not make sense to ask her to post very long ABC texts instead, with the additional drawback that the information about velocity/volume, stereo position, etc. is lost (if there was any ...).

NWC is a notation software (including accidentals etc., not just MIDI), so I wonder whether its users also use nwc2abc, or why not. I am not an NWC user myself, and, as I must admit, not a good ABC typist either, so I sometimes convert suitable MIDI files to ABC for posting here, with reasonable success. Software with direct ABC export would be preferable, of course. Rumour has it that things are on their way, e.g. with MuseScore, but I do not know anything definite.
