■ SOUND Page FILTER Filter is a processor that changes the timbre or tone of a sound by either blocking or passing a specific frequency range. The parameters below determine the overall timbre of the sound by boosting or cutting a certain frequency range. In addition to making the sound either brighter or mellower, Filter can be used to produce electronic, synthesizer-like effects. [1 ▲▼] BRIGHT. (Brightness) Determines the cutoff frequency or Volume effective frequency range of the filter (see diagram). Higher values result in a brighter sound. Cutoff Frequency These frequencies are "passed" by the filter. Cutoff range Frequency (pitch) 2 [2 ▲▼] HARMO. Determines the emphasis given to Volume (Harmonic con- the cutoff frequency (resonance), tent) set in BRIGHT. above (see dia- gram). Higher values result in a more pronounced effect. Resonance Frequency (pitch) Voices - Playing the Keyboard - EG The EG (Envelope Generator) settings determine how the level of the sound changes in time. This lets you reproduce many sound characteristics of natural acoustic instruments-such as the quick attack and decay of percussion sounds, or the long release of a sustained piano tone. Level ATTACK DECAY Key on Sustain Level RELEASE Time Key off [3 ▲▼] ATTACK [4 ▲▼] DECAY [5 ▲▼] RELES. (Release) Determines how quickly the sound reaches its maximum level after the key is played. The lower the value, the quicker the attack. Determines how quickly the sound reaches its sustain level (a slightly lower level than maximum). The lower the value, the quicker the decay. Determines how quickly the sound decays to silence after the key is released. The lower the value, the quicker the decay. VIBRATO Vibrato is a quavering, vibrating sound effect that is produced by regularly modulating the pitch of the Voice. Pitch SPEED DELAY DEPTH Time [6 ▲▼] DEPTH [7 ▲▼] [8 ▲▼] SPEED DELAY Determines the intensity of the Vibrato effect. Higher settings result in a more pronounced Vibrato. Determines the speed of the Vibrato effect. Determines the amount of time that elapses between the playing of a key and the start of the Vibrato effect. Higher settings increase the delay of the Vibrato onset. 12 CVP-509/505/503/501 Reference Manual
