I've always found the glide on polysynths to be "dumb" in polyphonic mode. Instead of gliding all notes of chords played in succession towards the same direction, it glides each voice according to their last note. And since voices are "recycled" for each new note played according to their availability, the result is a quasi random glide direction for each voice, which is NOT the way a glide should work.
There should be a polyphonic mode where voices are assigned fixed notes (especially with a 16 voice synth), so that when the glide function is engaged all notes of played chords would glides towards the same direction, from one chord to the other.
The REV2 is not the only synth to have this "polyphonic glide problem". Most others do. And it renders the glide unusable for me in polyphonic mode, because it always results in that "THX introduction effect" which is not what I want or need.
