Roland JP-8080 - How Voice Modulator Work

■ Vocal Morph Control
This analyzes the human voice (audio) which is input to the
Vocal Input of the Voice Modulator, and converts the char-
acteristics of that human voice into MIDI messages. These
MIDI messages can be used to modify multiple patch para-
meters simultaneously.
The width of parameter change will be the same as speci-
fied by Control Assign (p.84).
If the Morph Bend Assign Switch (p.85) is turned on, pitch
can be modified at the same time as other parameters.
The characteristics of the human voice will be converted
into the MIDI messages specified by Control Up (p.86) if
Vocal Morph Sens (p.111) is set to “+,” or converted into the
MIDI messages specified by Control Down (p.86) if Vocal
Morph Sense it set to “-.”

*1 When only one jack is connected
VOCAL/UPPER: The sound will be input only to the UPPER part.
INST/LOWER: The same sound will be input to both parts
(UPPER/LOWER).
*2 This switch will automatically change depending on the algo-
rithm setting.
If the algorithm is “SOLID,” “SMOOTH” or “WIDE,” it will be set
to FORMANT FILTER.
If the algorithm is “FLT BANK WIDE” or “FLT BANK NARROW,”
it will be sent to FILTER BANK.
*3 If the Voice Modulator switch
➊
is turned off, the result will be
the same as “off” even if [VOICE MOD SEND] is on.
*4 Even if [EXT] is turned on and an external sound is input,
sound will be produced only while note-on messages are being
received, in the same way as when the OSC 2 was selected.
However, the pitch cannot be controlled.
