Hi AllI don't know about Bendometer but I can recommend the Chronotron plug-in for Windows media player or winamp. You can change pitch and/or tempo for those cd's you have that are way out of tune to a harp or slow the tempo down to a crawl for figuring out tough licks.
Bendometer is a different animal. It's for letting you see if your bends are on pitch. See: http://www.harpsoft.com/
Peace and music, Dave
