FMOD (Filter Modulation): Adds a cyclical change to the filter cutoff frequency by applying LFO frequency modulations, to create wah-wah type effects. Larger values widen the range of cutoff frequency change. WAVE: Selects the LFO frequency signal used for modulation. You can select from the following types: Saw (Sawtooth) TIME Tri (Triangle) TIME S&HTr (Sample & Hold = random) TIME *S&HTr = Adds random changes to the pitch. (NOTE: Triangle waves will be applied for the AMOD and FMOD. Triangle wave is applied even if you select S&HTr for PMOD, when controlling the PMOD with the Modulation Wheel.) ELEM (Element) *Default settings of each element depending on the selected voice. SPEED: Sets the speed of the LFO frequency modulation. Larger values increase the speed. SLOW TIME FAST TIME PHASE INIT: Determines if the phase of the LFO frequency modulation wave is reset or not when a note is played. There are three types: Free, Retr (Retrigger) and Elem (Element). Free: The wave starts at the phase position where a note is played. + Phase when keyboard is played 0 TIME - KEY ON Retr (Retrigger): The wave starts at +/-0 phase position. + 0 TIME - KEY ON Elem (Element): The wave starts from the default phase position (Free or Retr) for each element of the voices. Settings: AMOD (Amplitude Modulation): -31 ~ +31 PMOD (Pitch Modulation): -63 ~ +63 FMOD (Filter Modulation): -15 ~ +15 WAVE: Saw, Tri , S&HTr, Elem SPEED: -63 ~ +63 PHASE INIT: Free, Retr, Elem Layer Edit 3 (independently applied to each Layer) The functions in this row provide parameters which are essential in creating a voice, such as FEG (Filter Envelope Generator) or PEG (Pitch Envelope Generator). The parameters can be set for each Layer in a Performance.

The FEG lets you shape how the tone, or timbre, of the voice changes over time, from when a key is hit, then released, and how the sound decays. There are four parameters: ATK TIME (Attack Time), DCY TIME (Decay Time), SUS LEVEL (Sustain Level) and REL TIME (Release Time). NOTE Generally, filters change the timbre by passing signals within a specific frequency bandwidth and cutting others. The CS1x features an LPF (Low Pass Filter) which passes the signals below the specified frequency point (cutoff frequency) and cuts the signals above it (see page 34). The FEG simulates the change of the filter envelope curve over time. NOTE Depending on the voice selected, changing certain parameters may not produce a noticeable effect. 31
