Filter - Korg R3 Owner's Manual

Knob [1]
FrmntSft (Formant Shift)
Shifts the cutoff frequencies of each of the
carrier's band pass filters. This will signifi-
cantly change the character of the vocoder
output.

37. FILTER

Here you can adjust the settings for the carrier's sixteen band-pass filters and modulator's envelope filter. You'll be using these parameters
frequently, since they play an important role in determining the character of the vocoder.
Knob [2]
[–2...+2] FcOffset (Fc Offset)
This continuously shifts the cutoff fre-
quency of each band-pass filter (Synthesis
filter) of the carrier.
"FrmntSft" and "FcOffset"
When "FrmntSft"=0 and "FcOffset"=0, the response of the carrier filters will match the
cutoff frequency of the modulator filters. The filter response is shifted upward or down-
ward in two discrete steps by the "FrmntSft." This can be adjusted upward or down-
ward a total of another two steps by using "FcOffset," giving you a total of four steps of
adjustment upward or downward.

[–63...+63] Vcd Reso (Vocoder Resonance)
Specifies the amount of resonance for each
band-pass filter of the carrier.
Increasing this value will emphasize the
regions near each cutoff frequency.

Knob [4]
E.F.Sens
[000...127]
Specifies the sensitivity of the modulator's
Envelope Followers. Lower settings of this
value will allow the attacks of the input sig-
nal to be detected more rapidly.
If you set this to Hold, the character of the
signal that is being input at that moment
will be held (Formant Freeze). Subse-
quently, the sound will retain that charac-
ter regardless of whether there is any in-
put.
If you set this to Hold when there is
no input signal present, there will be
no output even if an audio signal is
subsequently input.
If you write the program with this
value set to Hold, the program will
memorize the response of the signal
that was being held.
