Elements and Drum Keys
Elements and Drum Keys are the smallest "building blocks" in this synthesizer that comprise a Voice; in
fact, only one Element or one Drum Key could be used to create a Voice. These small sound units can
be built, enhanced and processed by a variety of traditional synthesizer parameters, such as Oscillator,
Pitch Filter, Amplitude, and LFO (shown below).
IMPORTANT
In Element Edit and Key Edit, you can edit the parameters only on the S90 XS/S70 XS Editor installed to your
computer connected to the S90 XS/S70 XS.

PITCH
Controls the pitch
of the sound.

Oscillator
This unit outputs waves which determine the basic pitch. From the Oscillator setup window of the S90
XS/S70 XS Editor, you can assign a waveform (the basic sound "building block") to each Element of a
Normal Voice or each Key of a Drum Voice. In the case of a Normal Voice, you can set the note range for
the Element (the range of notes on the keyboard over which the Element will sound) as well as the
velocity response (the range of note velocities within which the Element will sound). In addition, the XA
related parameters can be set in this unit.
Each waveform consists of the sample(s) created by recording the actual instrument's sound and
assigned to the set(s) of the keyboard and velocity.
For information on the Oscillator parameters, refer to pages
Pitch
This unit controls the pitch of the sound (wave) output from the Oscillator. In the case of a Normal Voice,
you can detune separate Elements, apply Pitch Scaling and so on. Also, by setting the PEG (Pitch
Envelope Generator), you can control how the pitch changes over time. Pitch-related parameters can
be set on the S90 XS/S70 XS Editor.
For details, refer to pages 47, 48, and 61.
Filter
This unit modifies the tone of the sound output from Pitch by cutting the output of a specific frequency
portion of the sound. Also, by setting the FEG (Filter Envelope Generator), you can control how the
Cutoff Frequency of the Filter changes over time. The Filter parameters can be set from the S90 XS/S70
XS Editor.
For details, refer to pages 50, 51,
Amplitude
This unit controls the output level (amplitude) of the sound output from the Filter block. The signals are
then sent at this level to the Effect block. Also, by setting the AEG (Amplitude Envelope Generator), you
can control how the volume changes over time. The Amplitude parameters can be set from the S90 XS/
S70 XS Editor.
For details, refer to pages 53, 55,
