Q110 Noise Source
Return to Modules
; "Click for large image of the Q110 Noise Source")
The Q110 Noise Source creates random waveforms useful for creating sounds such as thunder, explosions, drums, rainfall, breath simulation and more.
Noise can also be used to modulate other modules such as oscillators and filters to create more realistic, unpredictable sounds. An output level control is provided to eliminate the need for patching through an attenuator.
Three outputs are provided (available simultaneously):
- White Noise is composed of all frequencies in equal amounts.
- Pink Noise contains equal energy per octave.
- Low Frequency Noise low frequencies for modulation.
- ST Wrote: I finally figured out that using noise is the key to creating great percussion sounds.

- Power: +15V@8ma, -15V@8ma.
Basics
Noise is just a waveform consisting of many different frequencies.
It sounds like the static you hear on the radio or TV.
Pink noise is filtered White noise, and the Low Frequency output is simply filtered further.
Percussion
The Pink and White noise outputs can be used to create cymbals,
gun shots, and wind type sounds.
The White noise sounds higher in pitch than Pink noise.
Use fast attacks and slow release envelopes for most percussion sounds. Use a low pass filter with various resonance settings for wind and waves.
Tuning
Patch the White or Pink noise into a bandpass filter to
highlight certain frequencies.
The frequency can be controlled with a keyboard,
sequencer, envelope generator,
or oscillator.
Modulation
Use the Low Frequency output to control oscillators, filters
and other modules.
This can result in more realistic vibrato than modulating with a perfect sine wave.
Patch any of the Noise outputs into the Q117 Sample and Hold input then patch the output to control an oscillator or filter. This results in interesting random steps like that created by pressing random keys on a keyboard
