I also have most of my songs with chords saved in txt files in notepad. I also have a collection of midi files save on my computer I play along with at home. I also wish I could edit some of the midi files!
Not sure exactly what way you want to do it, using midi files for backing ?
Edit midi files ? mute instruments or lead ? add lyrics ?
Will throw out some ideas.
PowerTracks is a cheaper alternative to Biab if you are not gonna use all the stuff in Biab.
You can edit midi files in it, it will display chords/Lyrics.
Also
Karakan you can add the lyrics with chords in them to your midi files.
You can also get midi files with the lyrics already in (.kar) if your midi files don't have lyrics.
You can also screen capture it to video to play on a media player.
There are also hardware karaoke midi/cdg CD/DVD/USB players on eBay, if you have edited the midi files to have the chords inside the lyrics.

Welcome to the neighborhood.
Can the Big Lyrics Window do what you want?
Trevor
It will be great when the Big Lyrics/Chord window gets added in the Video Render Option ! along with a Scroll Ahead Notation/Tab Window Option (In the next version I hope or else you need to screen capture to videos)
Then you can play the video files on a USB stick/SD Card plugged in a portable AC/DC DVD/USB LCD Media Player sitting on a sheet music stand plugged into your AC/DC Portable AMP, a bit more hardier and reliable than carrying around a PC or Laptop and you just use the little remote the quickly scroll to and play/pause the next song.
