Tracking has acted like this for quite a few firmwares. Synth pitch drops an octave and pitch as modifier exhibits a similar glitch within a small range just flat of C#6 (21st fret high E), which can be heard here using a synth and bending up from C: http://files.getdropbox.com/u/28651/c_sharp_glitch.mp3
(If this can be corrected, could tracking also be modified to work at 24th fret E or beyond for bending? It reproduces F correctly now, but not E or anything higher than F.)
