Eventide H910 - Stereo Feedback; Stereo Link; Stereo Width

3.2.1 Stereo Feedback
The three buttons in this group allow you to control the feedback routing be-
tween the two H910 units. In ”Mono” mode, the output from a single unit only
feeds back into that unit. In ”Stereo” mode, the output from the top unit feeds
back into the bottom unit, and vice versa. In ”Both” mode, the output of each
unit feeds back into both itself and the other unit. An interesting application of
these modes is when using feedback combined with pitch shifting, which based
on the Pitch Ratios of the bottom and top units, can cause the incoming signal
to shift up/down continuously, shift up and then down continuously, or shift
away from a Pitch Ratio of 1 in both directions.
3.2.2 Stereo Link
The three buttons in this group allow you to more easily control the plug-in, by
linking corresponding controls in the bottom and top units. In ”Mono” mode,
all controls can be set independently. In ”Link” mode, changing a control on
one unit will cause the corresponding control on the other unit to follow that
change. ”Reverse Link” mode behaves much like ”Link” mode, but changing
the Pitch Ratio on one unit will cause the other unit’s Pitch Ratio to move in
the opposite direction. This is especially useful for creating stereo detuned and
doubling effects.
3.2.3 Stereo Width
Allows you to control how ”wide” the output of the plug-in is, from mono to
full stereo.
