ACCESS VIRUS RACK Envelope Section (Encoder) 107 ENVELOPE SECTION (ENCODER) í Filter Envelope ATTACK Determines the amount of time it takes for the filter envelope to rise to its maximum level. The higher the ATTACK value, the longer it takes for the envelope to rise to maximum volume after the start of a note. SUSTAIN Determines a variable level for the filter envelope at which it remains after the end of the DECAY phase (see appropriate section). The duration of the SUSTAIN phase depends on the TIME value (see appropriate section). DECAY Determines the amount of time it takes for the filter envelope to fade out. The higher the DECAY value, the longer it takes for the envelope to fall from its peak level to the SUSTAIN value. TIME Sets the bipolar time parameter for the filter envelope. It determines the envelope's response once it reaches the SUSTAIN phase (see appropriate section): If the knob is set to the center position (12 o'clock) indicated by the mathematical infinity symbol, then the SUSTAIN level remains constant through to the end of the note; if you turn it counterclockwise to the left (towards FALL), 108 CHAPTER 16 The Parameters then the level drops off at an increasing rate towards the minimum level; If you turn the knob clockwise to the right (towards RISE), the level rises at an increasing rate to maximum. SUSTAIN Sets a variable level value for the amplifier envelope at which it remains after the end of the DECAY phase (see appropriate section). The duration of the SUSTAIN phase depends on the TIME value (see appropriate section). RELEASE Determines the speed or rate at which the volume of the filter envelope decreases after the end of a note. The higher the DECAY value, the longer it takes for the envelope to fall from its current level to the minimum level, when the key is released. í Amplifier Envelope ATTACK Determines the amount of time it takes for the amplifier envelope to rise to its maximum level. The higher the ATTACK value, the longer it takes for the envelope to rise to maximum volume after the start of a note. TIME Sets the bipolar time parameter for the amplifier envelope. It determines the envelope's response once it reaches the SUSTAIN level (see appropriate section): If the knob is set to the center position (12 o'clock) indicated by the mathematical infinity symbol, then the SUSTAIN level remains constant through to the end of the note; if you turn it counterclockwise to the left (towards FALL), then the level drops off at an increasing rate towards the minimum level; If you turn the knob clockwise to the right (towards RISE), the level rises at an increasing rate to maximum. RELEASE Determines the speed or rate at which the volume of the amplifier envelope decreases after the end of a note. The higher the RELEASE value, the longer it takes for the envelope to fall from its current level to the minimum level, when the key is released. DECAY Determines the amount of time it takes for the amplifier envelope to fade out. The higher the DECAY value, the longer it takes for the envelope to fall from its peak level to the SUSTAIN value. ACCESS VIRUS RACK LFO Section (Encoder) 109 LFO SECTION (ENCODER) í LFO 1 RATE Determines the speed or rate of the LFO. In polyphonic sounds, the manually selected RATE value deviates slightly from voice to voice to liven up the sound of the LFOs, which also oscillate polyphonically. When the LFO is synced up to the master clock, the desired note value is selected via the RATE knob. SHAPE Determines the waveshape of the LFO. You can select from a sine, triangle, sawtooth, pulse wave, a stepped random modulation (S&H; short for Sample & Hold) or a smooth random modulation (S&G; short for Sample & Glide). CONTOUR By LFO Contour you can now bend or "morph" (almost) all the LFO waveforms. A brief survey of the LFO Contour options for the different LFO modes follows: 01111111111111111112 1 LFO 1 Contour +0 61111111111111111154 110 CHAPTER 16 The Parameters SINE Contour morphs from sine to a triangle wave (Contour to the left) or to a square wave (Contour to the right). TRIANGLE Contour morphs from a triangle to a declining (Contour to the left) or ascending sawtooth (Contour to the right). SAWTOOTH Contour morphs from a linear declining sawtooth or decay to any exponentially declining decay(Contour to the left) or to a square (Contour to the right). SQUARE Contour modulates the pulse width of the square wave. í LFO 2 RATE Same as LFO 1 SHAPE Same as LFO 1 CONTOUR Same as LFO 1 KEYFOLLOW Same as LFO 1 KEY FOLLOW Controls the intensity of the KEY FOLLOW function - i. e. the rate at which the LFO follows the pitch of a played note. At a value of 0, KEY FOLLOW is deactivated. At a value of 127, the rate doubles with each octave. 01111111111111111112 í LFO 3 RATE Same as LFO 1 1 LFO1 Keyfollow Off 61111111111111111154 SHAPE Same as LFO 1 KEYFOLLOW Same as LFO 1 ACCESS VIRUS RACK LFO Section (Menu) 111 LFO SECTION (MENU) CLOCK When you set it to OFF, the LFO oscillates in the normal manner, independently of the global Master Clock (CLOCK TEMPO). When you enter a note value here, the LFO rate is synced up to the global master clock. [. . . ] If the antenna lead-in is 300 ohm ribbon lead, change the lead-in to co-axial type cable.
