26 Filter 1 & 2

Dave Smith Instruments

Resonance: 0...127—Emphasizes a narrow band of frequencies around

the cutoff frequency. On Filter 1, high levels of resonance can cause the

lter to self oscillate.

Filter 2 does not self oscillate at the maximum resonance setting.

Filter Mode: LP, Notch, HP, BP—This knob selects Filter 2’s mode of

operation. It transitions smoothly from low-pass to notch to high-pass

operation, allowing a blending of these modes. Band-pass operation is

selected with the BP switch. Each lter mode has its own characteristic

sound and function. As noted previously:

• Low-pass: passes frequencies below the cutoff frequency

• Notch: removes frequencies in a notch centered around the cutoff frequency

• High-pass: passes frequencies above the cutoff frequency

• Bandpass: passes a band of frequencies centered around the cutoff frequency

On the front panel, band-pass mode is selectable only through the bp on/off

switch. However, you can actually smoothly transition between normal and band-pass

operation by choosing

F2-normal-bp as a modulation destination in the mod matrix.

Filter Routing: Series, Parallel—This knob selects a variable blend of

serial or parallel processing by Filters 1 and 2. In series, audio is passed

rst though Filter 1 then Filter 2. In parallel, audio is passed simultane-

ously through each lter individually.

Oscillator Split: Off, On—When enabled, this switch sends oscillators 1

& 2 to Filter 1 and oscillators 3 & 4 to Filter 2.

Boost: 0...127—(In the filter 1 tab of the display) This boosts the

output of Filter 1, making it possible to add makeup gain to the post-lter

signal level or even overdrive the lter output and add harmonic distortion.

Key Amount: 0...127—(In the filter 1 and filter 2 tabs of the display)

Sets the amount of modulation from the keyboard to the lter’s cutoff

frequency. In simple terms, setting a value here means that the higher the

note played on the keyboard, the more the lter opens. This is useful for

adding “brightness” to a sound as higher notes are played, which is typically

how acoustic instruments behave. A setting of 64 will step the lter in semi-

tone increments for each note, 32 would be quartertones, and so on.
