Filter; Filter & Eq; [F3] Filter; Fltr&Eq - Yamaha A4000 Owner's Manual

3. FILTER

You use this function to set the sample's filter type, filter char-
acteristics, and equalization. You can also set the way that fil-
ter strength varies with respect to velocity and keyboard
location.
• You can use filter-EG settings and LFO settings to create variations
in filter cutoff frequency over time. (page 138, 144)
• The [COMMAND/EXIT] button gives you rapid access to a number
of helpful commands while you are working with this function. For
example, you can use the [COMMAND/EXIT] button when you
want to save your edit results to disk, or when you want to cancel
your new changes and restore the previously saved data.
Press the [EDIT] button and then the [F3] button to go to the
Filter function.
2 display pages are provided: Fltr&EQ (Filter & EQ), and
FltrScal (Filter Scaling — page 135).
• See the "Basic Operation" section on page 78 for details on switch-
ing between display pages.

• Bypass ........ No filter.
• LowPass1.... Low-pass filter #1. (A low-pass filter blocks out
all frequencies above the cutoff frequency.)
• LowPass2.... Low-pass filter #2. Offers much higher Q (reso-
nance) than low-pass filter #1.
• LowPass3.... The characteristics of this low-pass filter are
somewhere between LowPass1 and
LowPass2.
• HiPass1 ....... High-pass filter #1. (A high-pass filter blocks
out all frequencies below the cutoff frequency.)
• HiPass2 ....... High-pass filter #2. Offers much higher Q (res-
onance) than high-pass filter #1.
• BandPass .... Band-pass filter. (Allows only frequencies near
the cutoff frequency to pass; blocks out all
higher and lower frequencies.)
• BandElim..... Band-eliminate filter. (Blocks out the frequency
range around the cutoff frequency, while allow-
ing higher and lower frequencies to pass.)
• Peak1 ........... A filter with an emphasis peak at the cutoff fre-
quency.
• Peak2 ........... With this filter the original sound is mixed with
the sound of the Peak1 filter.
• 2Peaks ........ A combination of two peak filters.
• 2Dips ........... A combination of two band elimination filters.
• DualLPFs..... A combination of two low-pass filters.
• LPF+Peak ... A combination of a low-pass filter and a peak-
ing filter.
• DualHPFs .... A combination of two high-pass filters.
• HPF+Peak.... A combination of a high-pass filter and a peak-
ing filter.
• LPF+HPF ..... A combination of a low-pass filter and a high-
pass filter.
