Detuned oscillators periodically beat against each other at a certain frequency. CBD sets
the beating frequency between low and high notes or retains a constant beating frequency
across the keyboard range. Choose a CBD value to detune the harmonics/beating of
low note frequencies in a ratio proportionate to the fundamental tone of the upper note
frequencies.
CBD offers five values:off, 25%, 50%, 75%, and 100%. If you choose 100%, the phasing
beats are almost constant across the entire keyboard range. This value may, however, be
too high, because the lower notes might be overly detuned at the point where the phasing
of the higher notes feels right. Try lower CBD values in cases where the bass notes are a
little too far out of tune with the upper keyboard range.
The reference pitch for CBD is C3 (middle C):its (de)tuning is constant, regardless of the
chosen CBD value.
Balance MainStage ES2 oscillator levels
The position of the pointer in the Triangle is described by two parameters—x and y
coordinates—which are used when automating the oscillator mix. These parameters, called
OscLevelX and OscLevelY, are available as targets in the router.
Drag the pointer in the Triangle to crossfade—set the level relationships—between the
three oscillators. This is self-evident in use. If you move the pointer along one side of
the Triangle, it crossfades between the two closest oscillators, and the third oscillator is
muted.
The position of the pointer (x and y coordinates) in the Triangle can also be controlled with
the Vector Envelope. Because the Vector Envelope features a loop function, it can be used
as a pseudo-LFO with a programmable waveform. For more information about this feature,
see Use the MainStage ES2 Vector Envelope.
Modulate triangle coordinates with the modulation wheel
1. In MainStage, set up a modulation routing as follows:modulation target OscLevelX,
source ModWhl. Adjust the intensity.
2. Set up a second modulation routing as follows:modulation target OscLevelY, source
ModWhl. Adjust the intensity. You can choose other sources for these targets.
