Using, Creating and Editing Voices Voice Creating-Voice Set SOUND ● 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. BRIGHTNESS Determines the cutoff frequency or effective frequency range of the filter (see diagram). Higher values result in a brighter sound. Volume Cutoff frequency These frequencies are "passed" by the filter. Frequency (pitch) Cutoff range HARMONIC CONTENT Determines the emphasis given to the cutoff frequency (resonance), set in BRIGHTNESS above (see diagram). Higher values result in a more pronounced effect. Volume Resonance Frequency (pitch) ● 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. ATTACK Determines how quickly the sound reaches its maximum level after the key is played. The lower the value, the quicker the attack. DECAY Determines how quickly the sound reaches its sustain level (a slightly lower level than maximum). The lower the value, the quicker the decay. RELEASE Determines how quickly the sound decays to silence after the key is released. The lower the value, the quicker the decay.
