The main Menu offers several options which can
be selected with the corresponding Soft buttons
(F1...F8). See also page 2.38 for further expla-
nations.

Activates the program which is able
to read samples from previous
Generalmusic Series instruments (S,
WX, SX) and disk-based samples of
various formats. Also permits the re-
ception and transmission of samples
via Midi and the creation of new
Waveforms. Sample Translator is
discussed separately on page 2.44.
Allows you to choose one of the 5
Algorithms available.
Allows you to Create, Import or De-
lete layers as required.
Sets the velocity and key ranges for
each layer allowing you to create
splits and velocity switching between

layers.

Escapes definitely from the Edit of
the Sound.
Allows you to save your modified
Sound to the PS/GPS Sound Library
(RAM) and escapes from Edit Sound
definitely.
Available in all Edit pages, Compare
temporarily assigns the original pa-
rameter status of the current edit
page to the Sound in edit to compare
the Sound before and after the modi-
fications. Pressing Compare acti-
vates two new commands:
Copy (F7) Copies the recalled pa-
rameter status to the Sound in edit,
cancelling all the modifications made
in the current edit page and escapes
from "Compare" mode.
Compare exit (F8) Escapes from
"Compare" and retains the modifica-
tions made to the sound in the cur-
rent edit page.
LAYERS
○ ○
The first thing you need to know, when you enter
the EDIT SOUND menu to edit a sound, is that
all PS/GPS sounds are created using either 1, 2
or 3 LAYERS. After entering EDIT SOUND, look
at the extreme left column of the Edit Sound menu
showing three Soft options.
These are the layer select options (L1, L2, L3)
which can be selected in any Edit Sound situa-
tion. Either 1, 2 or all 3 of these options will be
selected. This tells you how many layers the
current sound is made from.
Layer can be activated (L) and muted (M) by
toggling between the L and M status with the cor-
responding Soft button (A1, B2, C3). Muting a
layer can be useful when you want to hear only
the layer which you're currently editing without
listening to the others.
If an option shows the letters XX, this simply
means that the Sound in edit does not comprise
that particular layer.
So what actually is a layer ? In simple terms, a
layer is a sound. In fact, many of the PS/GPS
sounds are created using only one layer. When
more complex sounds are needed, up to three
layers can be combined together to form a single
sound. Since the process required to edit one
layer is exactly the same as for another, the ex-
planations in this section concentrate only on
editing a single layer. Creating multi-layer sounds
is a relatively simple process once you know how
to edit a single layer.

THE ALGORITHMS

Layers can also be of different types - single
waveform or dual waveform. Each layer is elabo-
rated by an associated "Algorithm" of synthesis.
