P07 Filter - Korg MMT RADIAS Owner's Manual

Program parameters
P06–3: MIXER
These parameters specify the output level of each oscil-
lator. The settings you make here will determine the in-
put level to the filter.
1: OSC1 Lvl (OSC1 Level)  OSC1 
Specifies the output level of oscillator 1.
2: OSC2 Lvl (OSC2 Level)  OSC2 
Specifies the output level of oscillator 2.
3: Noise Lvl (Noise Level)  NOISE 
Specifies the output level of the noise generator.

P07 FILTER

These are the individual parameters for filter 1 and filter
2, as well as parameters that affect the entire filter sec-
tion. Both filters are self resonating.
P07–1: FILTER1
1: Routing  ROUTING 
Specifies the routing (connection) between filter 1 and
filter 2.
This setting will affect the maximum number of
voices that can be played at one time.
Single
Only filter 1 is used.
Serial
Filter 1 and filter 2 are connected in series.

2: FiltBal (Filter1 Balance)  FILTER TYPE 
[LPF24...LPF12...HPF...BPF...THRU]
Selects the filter type. Intermediate settings will produce
a response that is between the two filter types.
LPF12 (–12dB/oct), LPF24 (–24dB/oct)
LPF (Low Pass Filter) is the most common type of filter;
it passes the frequencies below the cutoff frequency and
cuts the region above. Raising the cutoff frequency
("Cutoff" value) will produce a brighter tone. The
24dB/octave filter (also known as 4-pole; versus the
12dB /octave also known as a 2-pole filter) cuts the
sound below the cutoff frequency at steeper curve and is
useful for bass sounds with more "punch."

–24dB/oct
Cutoff
BPF (–12dB/oct)
BPF (Band Pass Filter) passes the frequencies in the re-
gion of the cutoff frequency, and cuts all other frequency
regions. Use this when you want to emphasize just a
specific portion of the sound.
BPF (Band Pass Filter)
Cutoff
HPF (–12dB/oct)
HPF (High Pass Filter) passes the frequencies above the
cutoff frequency and cuts the region below. Use this
when you want to make the tone thinner. However, rais-
ing the cutoff frequency too far will drastically reduce
the volume.
