This chapter tells you most of what you need to know about the Arabic
Scale. Some Arabic Scale editing tasks can also be performed in the
General section (see the MIDI/GENERAL chapter for more details).
To simplify the explanations, you can reset your WK1 Oriental so that the
instrument is restored to its default status (use the “System Reset” operation
explained at the end of the Intro chapter, page 1.3).
WHAT IS THE ARABIC SCALE ?
While so-called “Western” music is based on the use of a single intonation
scale (Equal scale), Oriental music boasts the use of several different “Arabic
Scales”, all, however, based on the lowering of the pitch by 1/4 of a tone of
one or more notes of the standard chromatic scale.
The name “Arabic Scale” is a general term which describes all the possible
configurations which can be obtained by lowering the pitch (always by 1/4
of a tone) of one or more notes within a standard octave.
WHERE IS THE ARABIC SCALE ?
The control centre of the Arabic Scale consists of two distinct sections,
both located on the left part of the WK1Or’s control panel: the ARABIC
SCALE and the MEMORY .
The ARABIC SCALE section is easily identified by the 12 circular buttons
laid out in the same manner as an octave of black and white notes.
The Arabic Scale MEMORY is located above the Arabic Scale, adjacent to
the Style/Song selection keypad. This section groups together several dif-
ferent functions. Here’s a breakdown of each function:
Memory 1, 2, 3, : memory slots for preset or user-programmed
Arabic Scales;
Cancel : cancels the selected Arabic Scale;
Store : memorizes user-programmed Arabic Scales.
HOW TO RECALL A PRESET ARABIC SCALE
The Arabic Scale Memory section contains 4 preset (ROM) Arabic Scales
(1, 2, 3 and 4). The Arabic Scale configurations memorized in these four
presets are factory-set and cannot be permanently erased from memory.
They can, however, be temporarily replaced by user-programmed scales
for as long as you wish. They are restored to their default settings using the
System Reset operation. The default configurations are those shown in
the margin opposite.
1. Press one of the 4 Memory buttons (1, 2, 3 or 4) to select a preset
Arabic Scale.
The button pressed is identified by a LED which lights up. Each
