Envelope parameters: The area to the right of the filter parameters contains the
envelope parameters, which control the level of the sound over time. See Logic Pro ESE
envelope parameters.
Output parameters: The area at the extreme right houses the switches for the integrated
modulation effects and the Volume knob, which is responsible for the main output
level. The effects can be used to color or thicken the sound. See Logic Pro ESE output
parameters.
Extended parameters: Not shown in the image, the extended parameters are accessed
by clicking the triangle at the lower left of the interface. These parameters include bend
and tuning functions. See Logic Pro ESE extended parameters.
Logic Pro ESE oscillator parameters
The synthesizer oscillator generates a waveform, which is then sent to other portions of
the synthesizer engine for processing or manipulation.
Oscillator parameters
Wave knob: Select the waveform of the oscillator, which is responsible for the basic
color of the tone. The leftmost setting of the Wave parameter causes the oscillators
to output sawtooth signals. Across the remaining range, the oscillators output pulse
waves, with the average pulse width determined by the Wave parameter position.
4, 8, and 16 buttons: Switch the pitch in octaves—transpose it up or down. The lowest
setting is 16feet, and the highest is 4feet. The use of the term feet to determine
octaves comes from the measurements of organ pipe lengths. The longer and wider the
pipe, the deeper the tone.
