Algorithm List
Vocoder2 (19)
This is a 19-band vocoder. Provides clear sounds that used to be impossible with the previous vocoders.

Input L
(Instrument)
Input R(Mic)
• Instrumental sounds are input into the L channel side of Effect. Therefore, it is required to insert-connect "Lch" of Effect to the channel handling instrumental
sounds. Similarly, vocal sounds are input into the R channel side of Effect. Insert-connect "Rch" of Effect to the channel handling vocal sounds.
• "Vocoder2 (19)" cannot be used on EFFECT2, 4, and 6 (even-numbered effects).
• When "Vocoder2 (19)" is used on EFFECT1, 3, and 5 (odd-numbered effects), EFFECT2, 4, and 6 (even-numbered effects) cannot be used.
Difference between Vocoder and Vocoder 2
Compared to Vocoder, Vocoder 2 has a significant number of frequency bands as points. It also makes it possible to make
fine adjustment including adjustment of the input sensitivity of the microphone and location of sounds as well as setting the
input level for instrumental sounds and removing noise. All this yields clear human voices.
"Envelope" for defining sound characteristics
Each sound has its own envelope. An envelope gives characteristics to the sound and functions as a significant factor for the
human ear to distinguish different sound types. On Vocoder 2, you can use Envelope to give the following characteristics.
Sharp: Enhances human voice.
Soft: Enhances instrumental sound.
Long: Vintage sound with long reverberation.
Sound location
Pan Mode (PanMode) can be used to specify how Vocoder sounds should be located.
Mono: Locating in the middle.
Stereo: Stereo (Odd-number frequencies are located to the left and even-number frequencies to the right.)
L→R: Lower frequencies are located to the left and upper frequencies to the right.
R→L: Lower frequencies are located to the right and upper frequencies to the left.
Sounding instrumental sounds with the formant fixed
While inputting voice through the microphone, instrumental sounds can be sounded at the same vocal formant. For example,
when saying "a-i-u-e-o" into the microphone, set "Hold" On at the moment the speaker is on the "i" sound to issue an
instrumental sound with the formant of the "i" sound.

Setting Function
The pitch is specified as in the instrumental sound while the tone is output in the human voice.
Sharp, Soft, Long Defines characteristics of the sound.
Mono, Stereo, L→R, R→L Defines how the sound is located.
On, MIDI Specifies that an instrumental sound is or is not issued with the formant fixed.
0–100 Sets the input sensitivity of the microphone.
0–100 Sets the input level of the instrumental sound.
0–100 Sets the tone of the vocoder.
0–100 Sets the amount of the sound after passing through the microphone HPF should be mixed into the
Vocoder output.
Thru, 1.0–20.0 kHz Sets the frequency at which HPF on the vocal sounds through the microphone starts taking effect.
Sets this to "Thru" if HPF is not desired.
L63–R63 Sets the panning of vocal sounds through the microphone.
Sets the volume to start muting noise on the instrumental sound input.
Adds spaciousness and depth to the sound.
On, Off Turns the chorus on or off.
0.1–10.0 Hz Sets the rate of modulation.
0–100 Sets the depth of modulation.
0–50 ms Sets the time delay from when the direct sound begins until the chorus sound is heard.
0–100 Sets the volume balance between the chorus sound and the direct sound.
