6.4a Selecting a Preset Tuning Table >
1. Press the GLOBL master button.
3. Select the desired scale type EQUAL (even-tempered), JUSTMaj (major scale just ma
intonation), JUSTMin (minor scale just intonation), MEANC (mean tone tuning, key l
of C), USER1, and USER2 (the latter are user-programmed scale; see below).
To hear the difference between just and even-tempered scales, play an interval of a E
third or sixth with the EQUAL scale type. Now play the same interval using JUSTMaj. FS
It will probably sound out of tune at first, but listen for a while then switch back to E
EQUAL; this scale will now sound out of tune, because, in actuality, the third and sixth
are slightly sharp compared to what they should be in theory.
6.4b Creating Your Own Tuning Tables
You can also create two custom tuning tables for particular ethnic scales, such as In-
dian ragas.
1. Press the GLOBL master button.
2. Select the USER Tuning page.
There are three parameters on this page:
# (1 or 2)
Selects user scale 1 or 2.
Note (C to B)
This selects the note of the octave to be tuned. The tuning specified in this octave is
repeated in other octaves.
Tuning Offset (-99 to +99 cents)
The selected note can be detuned over a range of -99 to +99 cents.
In addition to the options mentioned above, it is possible to set the DPM V3 for a
variety of alternate even-tempered tunings that include different numbers of notes per
octave, such as quarter-tone and eighth-tone scales. These types of scales may not
push your buttons from a melodic standpoint, but they are very helpful when creating
sound effects; after all, car crashes and door slams are rarely equal-tempered. On the
other hand, a 17-tone scale can be musically useful, assuming you find some comfor-
table keyboard mapping for it.
The key to this technique is to use Keyboard as the oscillator PMod and scale it ap-
