3. Pattern Voice submode 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 overtones in the vicinity of the cutoff point. The value is particularly effective on the attack part of the sound. 0101 1101 Filter cutoff -64,...,+00,...,+63 Filter resonance -64,...,+00,...,+63 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. Volume Attack Decay-1 Decay level Decay-2 Strike point Time • 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 moment when the "drum" is first "struck"). Note that excessively 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 editing, the edit settings are not effective on these voices. 0101 1101 EG attack -64,...,+00,...,+63 EG decay-1 -64,...,+00,...,+63 EG decay-2 -64,...,+00,...,+63 238 Chapter 5.
