Keys & Scales:
On the Vector, all pitch values are stored internally as either a note
number (similarly to MIDI), or an offset from a default note number. The
Key
sets what the default note is for a sequence. For the key of C, that
note is MIDI note number 60, which becomes 2V from a Pitch CV out.
Pitches within a sequence are actually stored as offsets from the default
note, which makes it easy to change or offset the default note for a
sequence. You can set the global Key (and Scale) for your project on the
first page of
Globals
, or also per-Part on the 2nd
Seq Ctl
page.
A
Scale
limits the note/pitch offsets that are available to use in a
sequence. In the Chromatic scale, all notes are available, in other scales,
some are not. When you pick a new scale, all pitch values for the
sequence are adjusted to fit the new scale. The scales available on the
Vector are those that are commonly used with 12-tone Equal Tempera-
ment tunings. The built-in scales are:
CHR
: Chromatic
MAJ
: Major
MIN
: Minor
DOR
Dorian
PHY
Phrygia
LYD
Lydian
MIX
Mixolydian
LOC
Locrian
Alternate Tunings & Notation:
A
Tuning
assigns, for Pitch CV outputs, a voltage value to each note, which
then becomes a frequency when sent to an oscillator. The default tuning is
12-tones per octave, equal temperament.
You can set an alternate tuning on the 2nd page of
Seq Ctl
settings.
There are several options built-in and you can load tunings in the MIDI
Tuning Specification (MTS) format. Many of the built-in tunings use an
alternate numeric notations. The Built-In tunings include:
NORM
: 12TET, displayed as note names.
ITVL
: 12TET, displayed as roman numerals.
NUMS
: 12TET, displayed as MIDI note numbers.
-3+7
: 12TET, displayed as voltage values from -3 to +7 volts.
-3+3
: Volt range of -3 to +3 volts, 20 divisions/octave.
0-5
: Volt range 0 to 5 volts, 24 divisions/octave.
ET13, ET14, ET15, ET16, ET19, ET24, ET31
: Equal temperament
tunigns, displayed with numeric note numbers and octave subscripts.
HRM12
: Harmonic series.
HRM60
: Wendy Carlos Harm. Twelve Tone
JIA7T
: JI scale with 7-limit Tritone at D#
LAT35
: JI, 3-5 Lattice from Carter Scholz
LAT37
: JI, 3-7 Lattice from Carter Scholz
To load your own MTS format tunings stored as .MID files, copy them to
the
F12_VS/TUNING
folder on the SD Card. Make sure each filename,
minus the extension, is 5 characters or less. You can then load 2 of them
per-project on the 2nd page of
GLOBALS: GENERL
, and then select them
per-Part on the 2nd page of
Seq Ctl
.
