[. . . ] Image-Line Toxic Biohazard Overview Toxic Biohazard features a hybrid synthesis engine, combining the best of FM and Subtractive synthesis. With the addition of a warm, analog-modelled filter and set of built-in effects, the Toxic concept remains one of convenience, simplicity, and superb sound quality. 6 customizable, anti-aliasing oscillators, each providing a rich, noiseless spectrum. A Warm, multimode, analog-modelled filter, featuring Low-Pass, Band-Pass, and High-Pass settings. [. . . ] FREQ OFFSET: This knob determines the frequency offset of the chosen oscillator. To increase it's value, "click-and-drag" your mouse pointer upwards while hovering over the knob. PHASE: Use to adjust the chosen oscillator's phase, from 0 to 360 degrees. To increase its value, "click-and-drag" your mouse pointer upwards while hovering over the knob. FREE: This button determines whether the chosen oscillator is key-synced or free-running. In its default OFF stage, the button will appear gray in color, and the oscillator will be key-synced. When ON this button emits a yellow glow indicating that the oscillator is free-running. VEL: The 'Velocity' slider determines how sensitive the specific oscillator will be to velocity cc's. To increase its value, "click-and-drag" your mouse pointer upwards while hovering over the slider. INIT: The 'Initial' slider determines the initial value the Attack stage of the envelope generator starts from. To increase its value, "click-anddrag" your mouse pointer upwards while hovering over the slider. ADSR envelope: Each oscillator has 4 controls that affect the amplitude of the chosen oscillator. ATK: Attack (this determines how quickly the oscillator fades in), DEC: Decay (determines how long the oscillator to take to reach the sustain point), SUS: Sustain (determines the level the oscillator will hold at once it reaches full decay, it will hold at this level until the note is released), and REL: Release (the rate at which the note fades after the key release). Image-Line Toxic Biohazard - Filter Filter Section Toxic Biohazard has a powerful filter section. It operates in both LowPass and HighPass modes and has it's own ADSR envelope generator as well as accepting modulation from various sources. Controls Mode: Toggles the filter between - Bypassed (---), Low-Pass (LP), Band-Pass (BP), and HighPass (HP). KEYTRK: This knob controls how closely the filter cutoff frequency will be tied to the MIDI key number pressed by the user. Lower keys will result in lower cutoffs, while higher keys will have the opposite affect. VELTRK: Determines how much velocity will effect the filter cutoff frequency. This controller has a range of -100 (envelope completely inverted) to 00 (envelope does not affect filter) to +100 (envelope heavily tied to filter). Filter Envelope Controls: Attack: The amount of time it takes for the envelope to effect the filter cutoff. Decay: The amount of time it will take the envelope to reach the desired sustain level. Sustain: The level at which the signal will rest after it has fully decayed. [. . . ] To activate the equalizer, click on the button under the "EQ" label and move your mouse up/down to boost/cut the respective frequency Delay Toxic Biohazard uses a multi-tap delay with 6 delay lines. SYNC: Sync's the delay time to host tempo (select from a menu of tempo multipliers). This control 'blends' the wet sound, what is achieved by using the higher number of delay lines. Chorus Chorus is an effect created by the slight detuning of multiple copies of the same sound (similar to a choir of voices). The controls contain parameters that affect the rate, time offset, shape and depth of detune. [. . . ]
