12. Filter cutoff, and filter resonance
• The CUTOFF value sets the cutoff frequency for the
QY700's low-pass filter. Adjustments to this value general
cause the sound to become brighter or darker.
• The RESONANCE value sets the filter's resonance. You
can use this adjustment to accentuate (or suppress) the over-
tones in the vicinity of the cutoff point. The value is par-
ticularly effective on the attack part of the sound.

13. EG attack, EG decay-1, and EG decay-2
• These values determines how the instrument's loudness
changes over time. Loudness development is controlled by
the envelope generator (EG). The following graph shows
the development sequence.
Attack
Volume
Strike point
• ATTACK
This value sets the time it takes for the sound to rise to its
peak volume, starting from its initial level of 0 (at the mo-
ment when the "drum" is first "struck"). Note that exces-
sively high values can produce an unnatural sound, since
the peak may be delayed until after the waveform has
reached its end.
• DECAY-1
This value sets the time it takes for the sound to fall from its
peak level to the internally set "decay level." (The decay
level itself cannot be edited.)
• DECAY-2
This value sets the time it takes for the sound to fall from
the decay level to the 0 level. Higher values cause the sound
to linger for a longer time.
• Note that some of these settings are ineffective on certain
instruments.
• Although it is possible to select an SFX-kit voice for edit-
ing, the edit settings are not effective on these voices.
