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:
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.
Both of these generate in-key harmonization.
Shift Down Take the input pitch assign, round it up a
half-step to an in-key pitch, calculate the
interval pitch then shift the interval pitch
down a half-step.
Shift Up Take the input pitch assign, round it down a
half-step to an in-key pitch, calculate the
interval pitch then shift the interval pitch up
a half-step.
Both of these generate out-of-key harmonization.
Unison and Octave interval pitches strictly follow the input pitch assign. An
example of how to use these follows the explanation of Voice Pitch intervals.
V1-V6 Pitch
The Res2>Plate effect has an individual pitch interval control for each voice
resonator. The range of each control is up or down any scale interval through five
octaves and Unison, for a total of 81 possible settings. For example: an interval
of up one-fifth reads "+5th", and an interval of up one octave and a fifth reads
"+1 Oct +5th". Down one-fifth reads "–5th", down one octave and a fifth reads
"–1 Oct –5th".
