Balance 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 cross-fade—set the level relationships—between the three
oscillators. This is self-evident in use. If you move the pointer along one of the Triangle’s sides, it
cross-fades between the two closest oscillators, and the third oscillator is muted.
Click or drag in the
Triangle to change the
level balance between
the oscillators.
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 Vector Envelope on page 69.
Modulate triangle coordinates with the modulation wheel
1 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.
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.
Choose free, soft, or hard from the Osc(illator) Start pop-up menu.
•
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 dier 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.
Note: Osc Start soft and hard result in a constant output level of the initial oscillator phase every
time the sound is played back. This may be of importance when you use the Bounce function of
Logic Pro at close to maximum recording levels.
