Balance Logic Pro 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 Logic Pro ES2 Vector Envelope.
Modulate triangle coordinates with the modulation wheel
1. In Logic Pro, 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.
Set Logic Pro ES2oscillator start points
The oscillators can run freely or can begin at the same phase position of their respective
waveform cycles each time a note is struck. This behavior is chosen in the Osc(illator) Start
pop-up menu.
Choose “free,” “soft,” or “hard” to change the waveform phase start position.
• Free: The initial oscillator phase start point is random for each played note. This adds
life to the sound. The downside is that the output level may differ each time a note
is played, making the attack phase sound less punchy—even if the performance is
identical each time—such as when the note is triggered by a MIDI region. This setting is
useful when you are emulating sounds typical of hardware analog synthesizers.
• Soft: The initial oscillator phase starts at a zero crossing for each played note. This
mimics the sonic character (and precision) typical of digital synthesizers.
• Hard:The initial oscillator phase starts at the highest level in the waveform cycle for
each played note. The extra punch that this setting can provide is audible only if the
ENV3 Attack Time parameter is set to a low value—a very fast attack, in other words.
This setting is highly recommended for electronic percussion and hard basses.
