LPF12 (Low Pass Filter12dB/oct)
A 2-pole (-12db/oct) dynamic LPF, designed to be used in
combination with an HPF (High Pass Filter).
LPF6 (Low Pass Filter 6dB/oct)
A 1-pole (-6db/oct) dynamic LPF with no resonance,
designed to be used in combination with an HPF (High
Pass Filter).
High Pass Filter
This only passes signals above the Cutoff frequency. You
can then use the Resonance parameter to add further
character to the sound. The MOTIF-RACK features two
High Pass filter types as follows.
HPF24D (High Pass Filter 24dB/oct Digital)
A 4-pole (-24db/oct) dynamic HPF with a strong
Resonance.
HPF12 (High Pass Filter 12dB/oct)
A 2-pole (-12db/oct) dynamic HPF.
Band Pass Filter
This only passes a band of signals around the Cutoff
frequency. The width of this band can be varied. The
MOTIF-RACK features four Band Pass filter types as
follows.
BPF12D (Band Pass Filter 12dB/oct Digital)
BPF12s (Band Pass Filter 12dB/oct Staggered)
Basically same as BPF12D, but with a shallower frequency
curve.
BPF6 (Band Pass Filter 6dB/oct)
BPFw (Band Pass Filter Wide)
Also the combination of a –12dB/oct HPF and LPF, but
allows a wider frequency band.
