Sequential Take 5 Compact Synthesizer - Manual (Page 31)

22 Filter Sequential
Filter Parameters
Cutoff: Sets the filter’s cutoff frequency.
Resonance: Emphasizes a narrow band of frequencies around the cutoff
frequency. High levels of resonance can cause the filter to self-oscillate
and generate its own pitch.
Drive: Increases signal input to the filter, boosting volume and adding
harmonic saturation and warmth. The effect of Drive can be subtle
depending on the amplitude and harmonic content of a signal.
Additional Filter Parameters (Program Menu)
Additional Filter parameters are accessible by pressing the front-panel
program
button and scrolling through the list that appears. The parameter
explained below does not appear on the front panel.
Key>LPF Freq: 0...127 —Sets the amount of modulation from the
keyboard to the filter’s cutoff frequency. Any setting above zero means
that the higher the note played on the keyboard, the more the filter opens.
This is useful for adding brightness to a sound as higher notes are played,
which is typically how acoustic instruments behave. When set to zero,
keyboard filter tracking is off, meaning that filter frequency is unaffected by
playing higher or lower notes on the keyboard. When set to 127, the filter
will track in half-step increments, which can be useful if you are using
the filter to generate a pitch through self-oscillation.
