Eventide H90 Harmonizer, User Manual

Sequence 2
Random
Spread: Controls the stereo spread of the voices. When set to -1 the Low voice is panned hard left,
the mid voice is panned center, and the high voice is panned hard right. When set to +1 this is
reversed. Intermediate values morph between these two extremes.
Slew Time: A slew on the Shift control. A large value will cause changes to the Shift parameter to
glissando.
Performance Parameters
Freeze (latching): Freezes the “High” and “Low” pitch shifted voices, the “Mid” voice (which is not pitch
shifted) is not frozen.
Shift (M): Moves the current value of the shift knob 1 position clockwise, wrapping if necessary.
-1oct +1oct shifts to -P4 +P5
-P4 +P5 shifts to -P5 +P4
-P5 +P4 shifts to -1 +1oct
+1oct +2oct shifts to +P5 +P12
+P5 +P12 shifts to +P4 +P11
+P4 +P11 shifts to +1oct +2oct
Quadravox
Quadravox is similar to Diatonic but delivers up to four pitch shifted voices (A, B, C, D) instead of two. You
can select the interval of each voice independently. You can also turn off any of the voices.
Note that it is possible to select OFF for all four voices. If you do, and the Mix knob is set 100% Wet,
there will be no output signal.
Mix: Wet/dry mixer, 100% is all wet signal.
Pitch A and C/Pitch B and D Mix: Controls the ratio of level Pitch A+C to Pitch B+D. With the knob
set full counter-clockwise, PitchC are set to equal level. Full clock-wise, sets Pitch B +
Pitch D to equal levels. The ratio of level of Pitch A to Pitch C and of Pitch B to Pitch D are
fi xed at
equal levels and cannot be changed.
Pitch Shift A: Selects the harmonic interval (pitch shift) for Pitch A. Set to minimum to turn OFF
voice A.
Pitch Shift B: Selects the harmonic interval (pitch shift) for Pitch B. Set to minimum to turn OFF
voice B.
