Oscillators

Increasing or decreasing the value from 50 causes the waveshape to become

asymmetrical. Lower values narrow the positive-going portion of the wave,

highervalueswidenit.Attheextremevalues,thepulsegoescompletelyat,

which allows for some interesting possibilities with pulse width modulation.

1/2 Mix: 100/0…0/100—Mixes the outputs of oscillators 1 and 2 in varying

amounts. A setting of 100/0 is 100% oscillator 1 and 0% oscillator 2. A setting of

0/100 is just the opposite. A setting of 50/50 is an equal mix of both.

Pitch: 0…C 10—Sets the base oscillator frequency over a 10-octave range, from

8Hzto8kHz,insemitones.C3ismiddleC,therstoctaveis0(C0,C#0,etc.),

thesecondoctaveis1(C1,C#1,etc.),andsoon.Notethatnoisesamplescannot

be tuned.

Fine: -50…+50—Fine tune control with a range of a quarter tone up or down.

Zero is centered. Steps are in cents (50 cents = ½ semitone).

Glide: 0...127—Sets the oscillator glide (portamento) rate. Glide is set indepen-

dently for each oscillator. Low values are faster. See also Glide Mode.

Sync 21: Off, On—Turns oscillator hard sync on. With sync on, whenever

oscillator 2 resets, oscillator 1 is forced to restart.

Sub Osc: 0...127—Controls the level of a square wave pitched one octave

below oscillator 1.

Osc Slop: 0...5—The amount of random oscillator frequency tuning slop. The

analog oscillators in Tempest are very accurate, and will not drift. This works

great for accurate sounds, and allows precise de-tuning. oSCillatoR SloP allows

subtle amounts of frequency drift. For larger amounts, use a random LFO.
