LFO (Low Frequency Oscillator)
LFOs are used to control various parameters cyclically, so that continuously repeat-
ing changes over time can be automated. For example, applying an LFO to pitch creates
the effect known as vibrato. Applying an LFO to amplitude creates a cyclical change in
volume known as tremolo. More exotic effects can be created by applying LFOs to filter
parameters, for creating repeating changes in harmonic content such as “wah-wah”
effects.
GigaStudio includes three discrete LFOs for Amplitude, Filter, and Pitch. The follow-
ing explanations apply to all three LFOs.
An external continuous controller, such as the Mod Wheel can also be used to apply
the LFO settings. This setting works the same way as the Internal depth settings but
you won’t hear its effect until the assigned MIDI controller is manipulated.
Freq (frequency)
Each of the low frequency oscillators may have any value between 0.10 and 10.00 Hz
and sets the rate at which it oscillates.
Int depth (internal control)
Use the internal depth to apply a “built-in” LFO depth:
Amp (amplitude) LFO +/-1200 volume modulation.
Filter LFO +/-1200 filter oscillation.
Pitch LFO +/-1200 pitch fluctuation in cents.
Ext depth (external control)
In addition to the internal depth, an external continuous controller, such as the mod
wheel, may be used to further modify the LFO depth.
Amp (amplitude) LFO +/-1200 volume modulation.
Filter LFO +/-1200 filter oscillation.
Pitch LFO +/-1200 pitch fluctuation in cents.
This concludes the Articulation section of the QuickEdit tool. We will now move on
the the Dimensions section located directly below the Articulation view. If the Dimen-
sion view is not visible, expand it by clicking the pointer net to the Dimension label on
the interace. By default, all the sections of the QuickEdit interface should be visible. The
hide/show pointers are provided for you to make more screen space available and to
simplify visual operations by hiding all but the sections necessary for edits.
