Resonance In the Resonant Chord algorithms: Res1>Plate and Res2>Plate, this row contains high cut filter and resonance controls for each voice, as well as master high cut and resonance controls for all voices.

Mstr Res,Mstr HC

Position 0 of the Resonance row contains two master parameters for the six resonator voices: Mstr Res and Mstr HC. (Press Load/✱ to toggle between them.) Mstr Res is a master resonance control for all of the resonator voices. It allows the resonance settings for all voices to be scaled over a range of 0- 100%. Use care when adjusting this value. The resonators will put out high levels if the input source has any components that are close in pitch to the resonator tunings.

The Mstr HC control allows the high cut filter settings for all voices to be scaled over a range of 0-100%.

V1Res,V1 HiCut-V6 Res,V6 HiCut

TheV1-V6 Res controls set the amount and polarity of feedback for each voice. The HiCut controls set the high frequency cutoff frequency of the 6dB per octave low pass filter for each voice.

RvbDesign The Reverb Deisgn row, available in every algorithm, contains parameters that affect the structural aspects of the reverb effect.

Size

Size sets the rate of build-up of diffusion after the initial period (which is controlled by Diffusion). The Size control changes a reverb sound from very large to very small. Generally, you should set this control to approximate the size of the acoustic space you are trying to create, before adjusting anything else. The size in meters is roughly equal to the longest dimension of the space. Audio is temporarily muted when Size is changed.

Duration

In the Inverse algorithm, Duration determines the length of time, in milliseconds, which passes before the cutoff in Inverse effects.

Attack

Attack is provided in the Plate algorithm to set the sharpness of the initial response to an input signal. High settings cause an explosive sound, while low settings cause the sound to build up more slowly with time. Attack only affects the level of sound within the first 50 milliseconds.

Diffusion

A Diffusion control is provided in all algorithms. It controls the degree to which initial echo density increases over time. High settings of Diffusion result in initial build-up of echo density, and low settings cause low initial build-up. Echo density is also affected by Size; smaller spaces will sound denser. To enhance percussion, use high settings of Diffusion. For clearer and more natural vocals, mixes, and piano music, use low or moderate settings of Diffusion.
