PITCH [F2]
You can set the basic pitch parameters for each
Element. You can detune Elements, apply Pitch
Scaling and so on. Also, by setting the PEG (Pitch
Envelope Generator), you can control how the pitch
changes over time.

[SF3]
Using the PEG, you can control the transition in pitch
from the moment a note is pressed on the keyboard to
the point at which it is released. As illustrated below,
the Pitch Envelope consists of five Time (transition
speed) parameters and five Level (pitch) parameters.
This is useful for creating automatic changes in pitch.
Furthermore, different PEG parameters can be set for
each Element.
The full names of the available parameters are shown
in the chart below, as they appear in the display.

FILTER [F3]
You can use the filter to change the tonal
characteristics of each Element, by adjusting overtones
(harmonic tones) included in the waveform of the
Element.
Cutoff Frequency and Resonance
Filters work by allowing the portion of the signal lower
than a given frequency to pass, and cutting the portion
of the signal above that frequency. This frequency is
referred to as the cutoff frequency. You can produce a
relatively bright or darker sound by setting the cutoff.
Resonance, on the other hand, boosts the level of the
signal at the cutoff frequency. By emphasizing the
overtones in this area, this can produce a distinctive
“peaky” tone, making the sound brighter and harder.
About the Filter types
The Low Pass Filter is shown in the illustration above —
however, the S90 features other Filter types as well.
LPF24D (Low Pass Filter 24dB/oct Digital)
A 4-pole (-24db/oct) dynamic LPF with a strong resonance.
