Meaning
Attack time. This is the time during which the sound goes from the
Start level (at the moment when you strike a key) to the Attack level.
Decay time. Time to go from the final Attack level to the beginning
of the Sustain.
Release time. This is the time during which the sound goes from the
sustaining phase, to zero. The Release is triggered by releasing a key.

This is a filter that cuts the high-frequency
region above the cutoff frequency.
This is the most common type of filter, and is
used to cut part of the overtone components,
making an originally bright timbre sound more
mellow (darker).
When the "Filter Type" is Low Pass Resonance,
Frequency
the cutoff will have a steeper slope.
