OASYS PCI 137
Scales
The OASYS PCI’s Scales allow any incoming MIDI note to create any pitch, with a
resolution of a single cent (1/100 of a semitone). Using Scales, you can create stretch
tunings, historic European tunings, scales with greater or fewer than 12 tones per
octave, and more.
Each Patch in a Program may have its own Scale, as assigned on the Program Edit
page (see page 86).
Each Scale is stored as an individual
fi le in the “Scales” folder, within the Korg
section of the OASYS PCI folder.
Editing Scales
Scales are text fi les, and can be edited using any standard text editing program,
such as SimpleText. Each fi le contains a single Scale.
Syntax
Tuning can be speci fi ed separately for each of the 128 MIDI notes. Each note must
be on a separate line; blank lines are OK.
Each re-tuned note needs to have at least three entries: the incoming MIDI note, the
resulting pitch (a note name), and
fi ne tuning (+/- 100 cents). Entries must be
separated by either spaces or tabs. Anything after the fi ne tuning is ignored, so you
can put comments at the ends of the lines.
For instance, below is a valid entry, including a comment, which causes a MIDI
note of D2 to be remapped to F3 (E3 plus 100 cents, a full half-step):
d2 E3 +100 D2 becomes F3.
There doesn’t need to be a line for every MIDI input note. If no re-tuning is
speci
fi ed, that note will simply be sent straight through to its normal pitch, A1 to
A1, C#3 to C#3, etc. If you want to have an entry for every note, you can also just
map input straight to output, as shown below:
F4 F4 0 Also could simply not use an “F4” entry.
Symbols
Notes must always include both letter and octave number.
Note letters can be lower or upper-case, so both “d2” and “D2” have the same
result.
The # sign is used for sharp. Flat notes should be expressed as sharp notes; for
instance, use A# instead of Bb.
Note and tuning range
The valid range of notes is C-1 to G9.
