PITCH (continued)
Res 2>Plate Pitch Parameters (continued)
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 selection 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.
Rule
This parameter has four values: Round Down, Round Up, Shift
Down, and Shift Up. Its exclusive purpose is to tell the interval
harmonizer what to do with out-of-key pitch assignments. The
values instruct the interval harmonizer as follows:
Both of these generate in-key harmonization:
• Round Down Take the input pitch assign, round it down a
half-step to an in key pitch, then calculate the
interval pitch.
• Round Up Take the input pitch assign, round it up a
half-step to an in key pitch, then calculate the
interval pitch.
