Yamaha CS1X Owner's Manual page 14

The secret behind the CS1x's exceptional quality sound is its ability to create rich and complex sonic textures in Performances, which are made up of
Layers of up to four AWM2 voices—either sounding simultaneously or mapped to various note and velocity zones across the keyboard.

! AWM2 WAVEFORM - The fundamental source
of the CS1x's sound is the sampled AWM2
waveform. There are hundreds preprogrammed in
ROM which are used by the Performances.
Available waveforms are organized in Banks. Each
AWM2 waveform has its own Program Number.
" AWM2 VOICE - The AWM2 waveform combines
with the oscillator, filter and amplifier to make up
a CS1x voice.
• PEG - The Pitch Envelope Generator controls how
the pitch changes over time.
INIT LEVEL (Initial Level) sets the initial pitch level
when a key is played.
ATK TIME (Attack Time) determines the time
required for a sound to reach its Attack Level after
a note is played.
ATK LEVEL (Attack Level) sets the initially targeted
level after a note is played.
DCY TIME (Decay Time) determines the time
required for a sound to reach its basic pitch from
the Attack Level while the key is held.
REL TIME (Release Time) determines the time it
takes for the basic pitch to reach the Release Level
after the key has been released.
REL LEVEL (Release Level) sets the final targeted
level after the key is released.

• FEG - The Filter Envelope Generator controls how
the timbre changes over time.
ATK TIME (Attack Time) determines the time
required for a sound to reach its maximum cutoff
frequency level when a note is played.
DCY TIME (Decay Time) determines the time
required for a sound to reach its Sustain Level from
the maximum level while the key is held.
SUS LEVEL (Sustain Level) sets the Sustain Level;
the cutoff frequency will be maintained at this level
for as long as the key is held.
REL TIME (Release Time) determines the time it
takes for the cutoff frequency to reach the level
preset for each voice after the key has been released.
• AEG - The Amplitude Envelope Generator controls
how the volume changes over time.
ATK TIME (Attack Time) determines the time
required for a sound to reach its maximum volume
level when a note is played.
DCY TIME (Decay Time) determines the time
required for a sound to reach its Sustain Level from
the maximum volume level while the key is held.
SUS LEVEL (Sustain Level) sets the Sustain Level;
the volume will be maintained at this level for as
long as the key is held.

# LFO - The Low Frequency Oscillator generates low
frequency signals which can be used to modulate
the PEG, FEG and AEG.
• PMOD - The LFO can apply Pitch Modulation to
the PEG to create vibrato effects.
• FMOD - The LFO can apply Filter Modulation to
the FEG to create wah-wah types of effects.
• AMOD - The LFO can apply Amplitude
Modulation to the AEG to create tremolo effects.
$ CONTROLLER - You can use several types of
controllers to manipulate various parameters in
realtime.
• MW - Use the Modulation Wheel to control
PMOD, FMOD, and Filter Cutoff.
• FC - Use the Foot Controller to control FMOD,
Filter Cutoff, and Variation Effect.
• Use the Sound Control Knobs to control AEG Attack
Time, Release Time, Filter Cutoff, and Resonance.
The ASSIGN 1/2 knobs can be specified to control
one of any number of parameters. (See the lists on
pages 27 and 29.)
