GLOSSARY - 131NOISE GENERATOR - A module which createsnoise. Noise generators often feature a builtinlow pass filter which allows them to produceseveral different kinds of noise.NORMAL - A connection which is premade betweenmodules before any cords are inserted. Anormal is usually made between modules whichare most frequently connected together.NOTCH FILTER- See Band Reject Filter.0OFFSET- The position of a waveform within acircuit’s dynamic range. E.g. a saw wave mightmove between 0 volts and +10 volts, or mightmove between -5 volts and +5 volts. The differencebetween the two is the offset.OPEN - A fader is said to be open when it is attenuatingthe least amount possible.OSCILLATOR - A module which produces varyingvoltage in a pattern called a waveform. Byproducing this waveform at different speeds (frequencies)the oscillator can change pitch. Bychanging the pattern of voltage, the oscillator canchange timbre. The oscillator produces the rawsound which is then shaped by other modules ofthe synthesizer.OUTPUT - A jack which can only put forth a signal,but can never accept an incoming signal.PPAN - See Panoramic Potentiometer.PANORAMIC POTENTIOMETER- A controlwhich determines how much of a signal will beoutput to the right channel path and how muchsignal will be output to the left channel path.PARAMETER - Something which can bechanged.PATCH - Referring to a particular sound createdon a synthesizer. Comes from the use of patchcords on the original modular synthesizers.PATCH CABLE - A cable used to connect differentsynthesizer modules together. Their colorindicates the kind of signal they are carrying.PAUL, LES - A guitarist who made great advancesin modern recording. His experiments definedstudio signal flow which is used today. Hisother inventions included multitrack recording,spring reverb, and a highly improved version ofthe electric guitar which is still used today.PHASE ANGLE - A measurement of phase indegrees. Like a circle, phase angle is measure in 0to 360 degrees.PHAT TUNING - A tuning technique in whichoscillators are intentionally put slightly out of tuneto create a warmer, richer sound.PINK NOISE - White noise which has had someof its higher frequencies attenuated with a low passfilter.PITCH - Frequency. Determined by the rate ofoscillation of an oscillator.PITCH BEND - A control found on most synthesizerswhich allows the user to smoothly raise orlower the pitch of all oscillators simultaneously.POLE - A Measure of the cutoff slope of a filter.One pole is equal to six decibels of volume reductionfor every octave higher or lower the soundgoes.
