I've seen a couple posts asking this question so I thought I'd post this here.   A couple easy ways to convert to gp5 from different types of files:   Online converter for gpx, ptb, midi, etc (nothing to download or install):  http://www.webtabplayer.com/   Directions for using Tuxguitar (needs a small add-on but very easy and Tuxguitar is free): http://www.wikihow.c...tar</span>-1.2)   I've heard reports that webtabplayer.com can produce errors in conversions, but I haven't had any yet.
