Normal Parts (AWM2), Normal Parts (FM-X), and Drum Parts

Normal Parts (AWM2)

These Parts are played conventionally from the
keyboard, with standard pitches sounding for each key,
generated by AWM2. A Normal Part consists of up to
eight Elements. Depending on the settings in the Part
Edit, these Elements are sounded simultaneously, or
different Elements are sounded according to the note
range, velocity range and the XA (Expanded
Articulation) settings (page 6).
The illustration shows an example of a Normal Part (AWM2). Since the six Elements here are distributed
across both the note range of the keyboard and the velocity range, a different Element sounds depending
on which note you play and how strongly you play it. In the velocity distribution, Elements 1, 3 and 5 sound
when playing the keyboard softly, while Elements 2, 4 and 6 sound when playing it strongly. In the note
distribution, Elements 1 and 2 sound in the lower range of the keyboard, Elements 3 and 4 sound in the
middle range, and Elements 5 and 6 sound in the higher range. In the velocity distribution, Elements 1, 3
and 5 sound when playing the keyboard softly, while Elements 2, 4 and 6 sound when playing it strongly. In
a practical example of this in use, a piano Part could be composed of six different samples. Elements 1, 3
and 5 would be the sounds of the piano played softly, over the respective note ranges, while Elements 2, 4
and 6 would be strongly played sounds, for each respective note range. Actually, this instrument is even
more flexible than this, since it allows up to eight independent Elements.

Normal Parts (FM-X)

These Parts are also played conventionally from the keyboard, with standard pitches sounding for each
key, generated by FM synthesis. The sound for a Normal Part (FM-X) is created by modulating a frequency
of a fundamental waveform with another waveform. An operator that generates a fundamental waveform is
a "carrier," and an operator that modulates these waveforms is a "modulator." The combination of a
number of Operators is called "Algorithm."
When the waveform output from the Operator is a simple sine wave, no harmonics are included other than
the fundamental tone. However, you can create harmonics by modulating the waveform with other
Operators. How harmonics can be created depends on the Modulators' output levels and the frequency
rates of Carriers and Modulators. On the other hand, the basic pitch is determined by Carrier's frequency,
and the output level is determined by the Carrier's output level. The figure described below shows a basic
way to create FM sound by using an analog synthesizer.
Modulator OP
Frequency ratio of the
Modulator and the Carrier
determines the base waveform
including specific harmonics by
the Oscillator.
Carrier OP
Carrier frequency determines
the pitch of the Oscillator.
Although the figure described above shows waveforms which are generated by two operators, the MODX
has eight Operators. The combination of a number of Operators is called an "Algorithm" and this
synthesizer has parameters for setting the Algorithm.

Drum Parts

Drum Parts are mainly percussion/drum sounds
that are assigned to individual notes on the
keyboard (C0 to C6). Unlike Elements, a Drum
key is equivalent to the corresponding note,
meaning that you cannot change its range.
Drum or percussion sounds are assigned to
each Drum Key. You can create various types of
Drum Parts by changing the drum or percussion sound assigned to each key and edit the parameters
such as pitch and EG.
