Scale Conversion - GEM GPS3600 Owner's Manual

METRONOME (F8)
Activates/deactivates the metronome.
TIME SIGNATURE
Valid for the entire Style. This parameter can be
modified only before starting a recording. If the
Style contains recorded events, this parameter
cannot be modified.
MEASURES
Determines the length of a riff expressed in meas-
ures (max 16).
TEMPO
Sets the playing speed (metronomic Tempo).
Valid for the entire Style.
KEY NOTE
Sets the reference key for the recording. KEY
NOTE indicates the key in which the original riff
is recorded. When you play the indicated chord,
the riff will play back in exactly the same manner
as recorded. If other chords are played, the riff
will be transposed accordingly.

SCALE CONVERSION

If you program a Style accompaniment based on
the Major scale, the PS/GPS arranger will auto-
matically convert a minor or 7th chord accord-
ingly. This allows you to limit your User Style
recording times by, for example, recording only
the Major riff of Variation 1, in order that when
you play with the recorded style, a minor or 7th
chord will be automatically adjusted for the
change. However, in harmonic terms, this type
of 'over-simplification' creates errors when using
the more complex chord structures. To overcome
this problem, the PS/GPS Scale Converter pro-
vides a selection of chord inversion systems,
based on algorithms in order to render the con-
version more musical.
You can program the Major chord only and set

the scale converter for the other two chords (mi-
nor and/or 7th). If, on a future occasion, you wish
to program also the respective riffs, the relative
Scale conversion will be ignored. The parameter
consists of two variable parts, corresponding to
the two complementary chords with respect to the
one being recorded.
If the "Off" setting is selected, the arranger car-
ries out the simplified conversion referred to. The
tables at the end of this chapter show how the
Scale Converter operates, both in the off status,
as well as for the Minor and 7th chords. Several
different solutions for each chord are provided
for.
On pages 5.12 and 5.13 you find Scale Conver-
sion tables for reference.
