CS1x Synthesis 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. REL TIME (Release Time) determines the time it 13 takes for a sound to sustain after the key has been released. # 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.)
