 CARRIER (set by [A]/[B] buttons)
Selects the musical instrument sound used as the source (Carrier) for the Synth
Vocoder. (The Carrier serves as the basic sound over which the vocal characteris-
tics are applied.)

CHORUS
Determines the attack time of the Synth Vocoder sound. The higher the value, the
slower the attack.
Settings: 1ms – 200ms
Determines the release time of the Synth Vocoder sound. The higher the value, the
slower the decay.
Settings: 10ms – 3000ms
Determines the HPF cutoff frequency for the microphone input sound. Setting this
to a low value results in a minimally processed input sound—in other words, close
to the original. Setting this to higher values emphasizes the higher frequency conso-
nant and sibilant sounds (making words easier to understand).
Settings: Thru, 500Hz – 16kHz
Determines the level of the microphone sound output from the HPF.
Settings: 0 – 127
Determines the amount (in BPF) by which the cutoff frequency value of the BPFs
(for the Inst Input) is shifted. This parameter can be used to change the character of
the Vocoder sound.
Settings: -2, -1, +0, +1, +2
Adjusts the cutoff frequencies of all BPFs (for the Inst Input) finely. This parameter
can be used to finely change the character of the Vocoder sound.
Settings: -63 – +0 – +63
Determines the level of the Carrier for the Synth Vocoder sound.
Settings: 0–127
Determines the octave setting of the Carrier for the Synth Vocoder sound.
Settings: -2 – +2
Determines the noise level which is input to the Synth Vocoder. This can be used to
emphasize sibilant and plosive sounds, and make the speech-like characteristics
more pronounced.
Settings: 0 – 127
Determines the specific type of effect applied to the lead Synth Vocoder sound. A
wide range of reverb, delay, modulation, distortion and other special effects are
available. You can edit the vocal effect by pressing the [G] (VOCAL EFFECT
EDIT) button (step 2 on page 104).
For a list of the effect types, refer to the Data List on the website.
Determines the amount of effect applied to the overall Synth Vocoder sound.
Determines the amount of reverb applied to the overall Synth Vocoder sound.
Determines the amount of chorus effect applied to the overall Synth Vocoder sound.
