Synth pane parameters
Double-click a parameter knob to reset it to the default value.
Double-click a parameter value field to enter in a new value. Press Return to complete the
operation.
• Details button: View or hide a slide-out pane which provides additional synthesis
parameters. See Sampler Synth Details.
• Tune knob and field: Raise or lower the pitch of the sampler instrument in semitone
increments. At the default (zero) position, no pitch change occurs.
• Fine knob and field: Tune the sampler instrument in cent increments—1/100th of a
semitone. Use this parameter to correct samples that are slightly out of tune.
• Filter On/Off buttons: Turn each filter section on or off. Each filter can have an
independent or shared envelope, defined in the Mod Matrix pane. Disabling the filter
section makes it easier to hear adjustments to other sound parameters because the
filter always heavily affects the sound.
• Filter Type pop-up menu: Choose the type and slope of the filter. See Sampler filter
types.
• Cutoff knob: Set the cutoff frequency of the filter. The Cutoff value also serves as the
starting point for any modulation involving the filter.
• In a lowpass filter, the higher the cutoff frequency is set, the higher the frequencies
of signals that are allowed to pass.
• In a highpass filter, the cutoff frequency determines the point where lower
frequencies are suppressed, with only upper frequencies allowed to pass.
• In a bandpass/band-rejection filter, the cutoff frequency determines the center
frequency for the bandpass or band-rejection filter.
• Resonance knob: Boost or cut the frequency area surrounding the cutoff frequency.
Very high Resonance values introduce self-oscillation, causing the filter to produce an
audible sine wave.
• In a lowpass filter, resonance emphasizes the frequencies at the cutoff frequency.
• In a highpass filter, resonance emphasizes the frequencies at the cutoff frequency.
• In bandpass filters, resonance emphasizes the portions of the signal—the frequency
band—that surround the defined frequency, set with the Cutoff knob. In Sampler,
Resonance defines the width of the frequency band.
• Drive knob: Overdrive the filter input, leading to a denser, more saturated signal, which
introduces additional harmonics. Drive affects each voice independently. When every
voice is overdriven individually—like having six fuzz boxes for a guitar, one for each
string—you can play extremely complex harmonies over the entire keyboard range.
They’ll sound clean, without unwanted intermodulation effects spoiling the sound.
Some Drive settings lead to a different tonal character. The way analog filters behave
when overdriven forms an essential part of the sonic character of a synthesizer. Each
synthesizer is unique in the way its filters behave when overdriven. Sampler is flexible in
this regard, allowing tonal colors that range from a subtle fuzz to a hard distortion.
• Filter configuration buttons: Switch between a series or parallel filter configuration.
