• HPF (High Pass Filter)
This only passes signals above the Cutoff frequency.
You can then use the Reso (Resonance) parameter
to add further character to the sound. Two types of
HPF are available.
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.
• BPF (Band Pass Filter)
This only passes a band of signals around the Cutoff
frequency. The width of this band can be varied. Three
types of BPF are available.

BPF6 (Band Pass Filter 6dB/oct)
The combination of a -6dB/oct HPF and LPF.
BPF12D (Band Pass Filter 12dB/oct Digital)
The combination of a -12dB/oct HPF and LPF.
BPFW (Band Pass Filter Wide)
Also the combination of a –12dB/oct HPF and LPF, but can
have a wider frequency band than the BPF12D filter.
• BEF (Band Elimination Filter)
This attenuates a band of signals around the Cutoff
frequency, but passes everything else.
BEF6 (Band Elimination Filter 6dB/oct)
• THRU
The filters are bypassed and the entire signal is
unaffected.
■ Gain
Set the Gain (the amount of boost applied to the
signal sent to the Filter Unit).
