Kit Piece Tone and Effect Smart Controls parameters
Given the huge number of Library kit piece patches, this list of parameters covers only the most frequently used kit piece tone and effect controls.
Attack knob: Set the length of the attack phase of the sound.
Body knob: Alter the depth of the sound, making it fuller and richer.
Bottom knob: Set the amount of low-end enhancement. This behaves like a bass control found on a guitar amplifier.
Color knob: Set the tonal color of the sound.
Crush knob: Reduce the overall bit resolution of the kit piece. Bit crushing introduces a lo-fi, gritty quality to the sound.
Decay knob: Set the length of the decay phase of the sound.
Delay knob: Set the amount of delay effect added to the sound.
Dirt knob: Add grit and fizz to the sound.
Distortion knob: Add a warm tube-like or digital distortion to the sound.
Envelope knob: Apply and set the intensity of a preset envelope shape to the sound.
Hi Cut knob: Set the high cut filter frequency. The sound is attenuated above this frequency.
Length knob: Use to alter the sustain, decay, or release phase of the sound.
Lo Cut knob: Set the low cut filter frequency. The sound is attenuated below this frequency.
Pan knob: Set the stereo position of the sound.
Pitch knob: Set the tuning of the sound in semitone steps.
Presence knob: Use to change the attack phase of the sound, making it bright and punchy, or soft and muted.
Reverb knob: Set the amount of reverb effect added to the sound.
Spread knob: Use to change the perceived stereo width of the sound.
Sub knob: Add a sine wave signal to the sound. The sine wave is an octave lower than the original sound.
Tone knob: Set the overall tonal color of the sound.
Volume knob: Set the output level of the sound.
