ity creates a higher resonance in the
filter bands, which therefore make the
overall sounds more artificial.
VOCODER ATTACK (Default: 0 (left) The
attack time of the envelope follower.
This parameter controls how fast the car-
rier bands react on a change of the mod-
ulator signal's frequency energy. Higher
values result in a "flabby", lazy, even
delayed response from the vocoder.
VOCODER RELEASE (Default: 0 (left) The
release time of the envelope follower.
This parameter controls how fast the car-
rier bands reflect if a certain frequency
disappears from the spectrum of the
modulator signal. Here, higher values
result in a kind of sustain in the carrier
bands. High attack and release times
lead to less speech recognition, although
it is possible to create a really nice
sounding synthesizer pads with.
VOCODER SOURCE BALANCE (Default: 0
(middle)) FILTER BALANCE creates a mix-
ture of the vocoder signal and the modu-
lator-respectively carrier signal. Turning
FILTER BALANCE to the left adds a cer-

tain amount of the carrier signal to the
vocoder signal. A turn to the right adds

. Turning the FILTER BALANCE hard
left or right can be used to monitor the
vocoder's input signals only.
VOCODER SPECTRAL BALANCE (Default:
64 (middle)) Spectral balance between
the higher and lower frequencies of the
vocoder signal. This parameter works
similar to a simple equalizer, which is e.g.
capable to increase the quality of
speech. The Spectral Balance highly
influences the overall character of the
vocoder.
Several vocoder related parameters can
be modulated by LFO-1 and LFO-2
LFO 1 RESO 1+2 modulates the band-
pass filter quality of the modulator and
carrier bank.
LFO 2 FILT 1 modulates the bandpass
filter frequency of the carrier bank.
LFO 2 FILT 2 modulates the bandpass
filter frequency of the modulator bank.
