Saccara SA-01
Ambience syntheser. 

Saccara's  purpose is to produce all sorts of ambient noise like wind and water. 

Saccara SA-01 consists of four sections:
-Modulators
  This section has 3 LFO's (Low Frequency Oscillator). The shape combobox selects a waveform. 
  You can choose between 
  -Sine
  -Triangle
  -Pulse
  -Sawtooth
  -Random
  The frequency is adjustable between 0.005 and 50 Hz.
  With 0.005 Hz the shape will repeat each 200 seconds.Ê
  The LFO outputs are connected to the other sections. Thus you can take any of the modulators 
  to control a value in the other section.Ê


-Noise
  The type combobox selects a noise type. Noise is kind of random values.
  Currently there only is the type Uniform White Noise.
  Other colors and derivatives are planned (Gaussian White Noise, Pink Noise, Brown Noise).

  The hold slider sets the sample & hold rate. Moving it sets the rate at which a new random value  
  is produced. In down position new values are produced at the samplerate SR. This means that
  each sample has a new random value. Moving the slider up produces random values for SR/2, 
  SR/4, SR/8 and so on thus producing lower frequencies.

-Filter
  The type combobox selects a filter type. With the filter you can change the color of the noise.
  Currently there are
    Classic LowPass
    StateVariable LowPass
    StateVariable HighPass
    StateVariable BandPass
    StateVariable Notch

  The frequency slider selects the frequency at which you want to operate. For a lowpass filter all 
  frequencies below are passed. With the quality slider Q you can adjust the sharpness at the
  selected frequency. This also is known as resonance. Setting the Q slider to 1.0 produces a self-
  oscillating effect.

-Channel
  The input combobox selects between the noise generator and the filter output as source.

  The level slider manipulates the volume which is shown in db. 0 db means full level, whereas -100 db 
  is not noticeable. You can mute the channel without affecting the current volume.

  The pan slider moves the sound between left and right position. The center button sets the balance 
  at the center position (0).

 The pitch slider changes the playback samplerate. At 1.0 you have the original pitch which you always 
  can reset with the button labeled Original. Moving the slider down changes the playrate down to 1/4 
  of the original frequency, moving it up produces a higher pitch up to approximately 2.5 SR.
