Algorithm List
Vocoder2 (19)
This is a 19-band vocoder. Provides clear sounds that used to be impossible with the previous vocoders.
fig.08-65
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 and 4 (even-numbered effects).
• When "Vocoder2 (19)" is used on EFFECT1 and 3 (odd-numbered effects), EFFECT2 and 4 (even-numbered
effects) cannot be used.
• "Vocoder2 (19)" cannot be used on the projects with 64kHz or higher sampling rate.
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.

Soft:
Long:
Sound location
Pan Mode (PanMode) can be used to specify how Vocoder sounds should be located.

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.
