From: "Ed Hayden" <ejh@ebmud.com> To: "'rolls@foxtail.com'" <rolls@foxtail.com> Subject: Duo Art Transposing Tracker Bar Date: Fri, 18 Sep 1998 11:14:47 -0700 In MMD Digest 98.09.12 Dick Merchant asked for pictures and info about the Duo Art Transposing Tracker Bar. I have never had a use for it other than playing with the key of the song. I understand that the Weber was custom built for a singer but I have nothing to support this. The tubing is brittle and shifting them with the tracker might cause failure. When shifting to the right the top 4 playing notes are cut off. Likewise, when shifted to the left the bottom 4 playing notes are cut off.
Picture 1 Shows the Tracker Bar with the shifting quadrant at the right side of the spool box.

Picture 4 Shows the valve boxes that cut off the treble or bass notes
