Playing and Editing Programs
Detailed Editing with Programs
You can create your own original sounds by edit-
ing the factory Programs, or by initializing a Pro-
gram (Bank D 127: Init. Program
from scratch. You can save these Programs into
any bank other than Bank G or g(d), which cannot

The three attributes of sound: pitch,
tone, and volume
Sound has three basic attributes; pitch, tone, and
To control these attributes, the X50 provides
"oscillator," "ﬁlter," and "amp (ampliﬁer)" sec-
The "oscillator" settings vary the pitch, the "ﬁlter"
settings modify the tone, and the "amp" settings
modify the volume.
The X50's "oscillator," "ﬁlter," and "amp"
On the X50, the settings that determine the "pitch"
are located in the PROG 1: Ed–Basic and PROG 2:
Ed–Pitch pages. In the Ed–Basic page you can
specify the waveform (multisample) and the basic
pitch of the waveform. In the Ed–Pitch page you
can specify how the pitch will follow the key-
board, and make other pitch-related settings.
"Filter" settings are made in the PROG 4: Ed–
Filter1 and PROG 5: Ed–Filter2 pages. These set-
tings adjust the tone.
Finally, "Amp" settings are made in the PROG 6:
Ed–Amp1/2 pages. These settings adjust the vol-
ume, and send the sound to the outputs.

These three sections determine the basic sound of
EG, LFO, keyboard tracking, AMS,
In addition to the sections described above, the
X50 provides ways in which the sound can be var-
ied according to time, key range, or various types
of performance expression. These are controlled
by modulators and controllers such as EG (enve-
lope generator), LFO (Low Frequency Oscillator),
keyboard tracking, AMS (Alternate Modulation
Source), Dmod (Dynamic modulation), the
[PITCH] and [MOD] wheels. You can use these
modulators and controllers to apply change to the
basic sound of the program.
Take a look at the diagram entitled "Program
structure and corresponding pages." Notice that
the audio signal ﬂows in the order of Oscillator/
Pitch → Filter → Amp. Also notice how modula-
tors such as EG and LFO can affect these blocks.
As shown in ﬁgure, a program consists of OSC 1/
2, effects, and the arpeggiator.
Each timbre consists of Oscillator/Pitch, Filter,
Amp, EG, and LFO blocks. You can create more
complex programs by using two oscillators
together in one program using the Layer feature.
Note: The Pitch EG is shared by OSC1 and OSC2.
The output of OSC 1/2 is sent to the insert effect,
the master effects, and the master EQ. The mixer
section lets you control the routing, so you can
specify where the sound will be sent.
