Electro-Harmonix V256 Vocoder Manual page 7

When the preset is recalled, the frozen sample as well as any drones that were saved will be
recalled. In order to clear the saved frozen sample, hold the MIC BYPASS footswitch without
any instrument input, or turn the pitch knob to fully CCW. This will clear the frozen sample
however if the preset is reloaded the frozen sample will return. In order to clear the frozen
sample from the preset, turn the pitch knob fully CCW so the frozen sample stops playing,
then save a new preset in the current mode.
This feature can be used together with the internal synthesizers and can also be used to
freeze MIDI triggered notes.
VOCAL TRANSPOSITION MODES
TRANSPOSITION
In this mode the V256 does not require an external instrument. The V256 will transpose the
vocal signal by an amount determined by the PITCH knob. At noon the transposition is at
unity. At fully CW it is +1 octave and at fully CCW it is -1 octave.
The BANDS knob can be used to control how quickly the intervals change when controlled by
a MIDI input. At noon, the transposition interval will change instantaneously. As the knob is
moved CW the notes will change to new intervals more slowly creating a portamento type of
effect. As the knob is moved CCW the notes will change to new intervals more slowly, and
vocal pitch changes will also be delayed. Blended with the original vocal, this effect can be
used to add complexity to a double tracked vocal sound where the V256 effect sound will
reach new vocal pitches a little slower than they are sung.
A MIDI controller can control the amount of transposition. When two notes are played
together, the interval between those two notes will be applied to the transposition. When a
MIDI note is played, the setting of the PITCH knob will no longer be relevant and the original
vocal pitch will be heard. As a second note is played along with the first note, the interval
created will be applied to the vocal transposition. The MIDI notes being played are irrelevant,
only the interval matters. When the MIDI notes are released, the transposition will go back to
where the PITCH knob is set.
INSTRUMENT CTRL
In this mode the V256 will replace the vocal pitch with the pitch of an external instrument.
The PITCH knob controls the threshold of how loud the instrument must be in order for the
V256 to replace the vocal note. At fully CCW, the instrument has the least effect, and at fully
CW the V256 will never revert back to the dry vocal pitch. The pitch will remain at the last
instrument controlled note until a new note is played.
