CHAPTER 7
The Parameters
Q-FACTOR
DEFAULT: 0 (LEFT)
The resonance parameter controls the quality of
the filter bands (like an equalizer’s q-factor). De-
pending on the filter select setting, the banks
are adjusted together or independently. FILT1 is
assigned to the carrier, FILT2 controls the mod-
ulator. A low quality factor of the carrier bank
leads to a fairly neutral reproduction of the car-
rier signal. A higher quality creates a higher res-
onance in the filter bands, which therefore make
the overall sounds more artificial. The effect is
less effective on the modulator bank. Here, the
filter quality controls the ”gab” in between the
individual filters. Depending on the modulator
signal, if you soften or tighten the ”gab,” it
could lead to interesting changes, although in
most cases this will result in a rather subliminal
change.
VOCODER ATTACK
DEFAULT: 0 (LEFT)
The attack time of the envelope follower. This
parameter controls how fast the carrier bands
react on a change of the modulator signal’s fre-
quency energy. Higher values result in a ”flab-
by”, 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 carrier 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 syn-
thesizer pads with.
VOCODER SOURCE BALANCE
DEFAULT: 0 (MIDDLE)
FILTER BALANCE creates a mixture of the voc-
oder signal and the modulator-respectively car-
rier signal. Turning FILTER BALANCE to the left
adds a certain amount of the carrier signal to
the vocoder signal. A turn to the right adds the
modulator signal.
Turning the FILTER BALANCE hard left or
right can be used to monitor the vocoder’s input
signals only.
