Lowpass

Tempest

Lowpass

Frequency: 0...164—Setsthelter

cutoff frequency over a range of

more than 13 octaves. This control

steps in semitones when turned

slowly, but smoothly controls the

lterwithoutstepswhenturnedata

faster rate.

4 Pole: On,Off—Selectsthelterconguration.Whenon,thelterisin4-pole

mode.A4-pole,low-passlterrollsofffrequenciesabovethecutofffrequencyat

aslopeof-24dB/octave.Whenoff,thelterisin2-polemodeandhasaslopeof

-12dB/octave and a more gradual roll-off of the higher frequencies.

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

cutofffrequency.In4-polemode,highlevelsofresonancecancausethelterto

self oscillate. In 2-pole mode, resonance is much more subtle.

Audio Mod: 0...127—Controls the amount of audio from oscillator 1 used to

modulatetheltercutofffrequency.Forlter-onlyaudio,set1/2 Mix in the

Oscillators section to 0/100, oscillator 2 Shape to Off, and oscillator 1 Shape to

the desired waveshape. This is useful for bell-like FM sounds. A wide range of

sounds can also be made using audio Mod with the oscillators routed normally

throughthelter.

Key > Freq: 0...127—Sets the amount of modulation from the note number—

fromeitherthebeat,thepads,orviaMIDI—tothelterfrequency.Sometimes

called key tracking in keyboard synths, because the cutoff frequency “tracks”

notesplayedonthekeyboard.Asettingof64willstepthelterinsemitone

increments for each successive note, 32 is quartertones, and so on.
