The Algorithms and Their Parameters

Res 2>Plate Pitch parameters

Pitch cont'd.

The voice resonators take the audio impulse from a delay voice and “resonate” it at a desired pitch. The Res2 effect is a “interval harmonization” pitch assign in that pitch changes generate interval pitches to be assigned to the six voice resonators.

Position 0 contains all of the pitch parameters which affect the voices in the remaining position in the row. Press Load/to cycle through the selections at position 0: Assign, Tuning, Active, Key, Scale, Root and Rule.

Assign This parameter has a range of C0 to G10 (128 pitches to be convenient for MIDI patching). As the value of this parameter is changed, each voice resonator is set to a pitch at the defined voice’s interval (described later).

Tuning This parameter allows you to tune the A440 reference of the box anywhere from 430.0-450.0Hz in 0.1Hz increments.

Active This parameter allows you to define the number of voice resonators which are active. You can choose from 0 (no resonators active) to 6. Setting the value to 1 will permit only Voice 1’s resonator to ring out. Setting the value to 2 will permit Voices 1 and 2 to ring out. A value of 6 uses all the voice resonators. A handy feature of this parameter is the ability to mute resonators. For example, you can patch this parameter to a footswitch or pedal, allowing you to drive the parameter value down to 0 at any time, causing the resonators to stop playing their last assigned pitches. You can then immediately drive it back up to the desired number of active resonators. This “clears” the note assign for the resonators, so they don’t go back to playing their previous pitches, but rather wait for the next pitch assign to come along before resonating.

Key This parameter establishes a key signature for the pitch selec- tion of the voice intervals. The range of this value is the 12 keys from C, C#, etc., up to B.

Scale This parameter establishes one of two scales of semitones: a standard Major scale (intervals of 2, 2, 1, 2, 2, 2, 1 half steps for the scale), or a Harmonic scale (intervals of 2, 1, 2, 2, 1, 3, 1).

Root This parameter (with values of 1-7) establishes the root of the scale which, when combined with the scale, defines the mode. For example, with a Major scale selected, roots 1-7 define the modes — Ionian (Major), Dorian, Phrygian, Lydian, Mixolydian, Aeolian (minor) and Locrian.
