Overview 

Your synth cannot be complete until you have lots of noise otherwise how else are you going to create the sound of the sea crashing on the shore line or that rumble of thunder. The Noise + S&H module not only has noise sources but also a sample and hold function. The term sample and hold describes rather well what the S&H does.

Features 

• White noise output containing a broad spectrum of all frequencies
• Pink noise output which contains more lower frequencies and less higher frequencies (white noise filtered by a low pass filter -3dB/octave)
• Red noise output which contains even more of the lower frequencies for a nice deep rumble (pink noise filtered by a low pass filter -3dB/octave)
• Blue noise is brighter than white noise with more higher frequencies than lower frequencies (white noise filtered by a high pass filter +3dB/octave)
• Purple noise output is brighter still and getting quite a thin sound with mostly high frequencies only (white noise filtered by a high pass filter +6dB/octave)
• Sample and hold function which can take the white noise as its input or an externally applied signal
• The sample rate for the sample and hold gate can be set using the sample rate control or from an external sample rate control voltage
