Modulation Modules; Lfo - Positive Grid BIAS MODULATION TWIN Product Manual

4. Modulation Modules

BIAS Modulation Twin comes with 2 major modulation modules, time-based and amplitude
module. Time-based module provides some manipulations of time occurs to a signal. Like
Chorus, Phaser, Flanger and so on. Amplitude module, in the other hand, provides the effect
to change the amplitude (volume) of the signal, creating tremolo or panning effects. With BIAS
Modulation Twin, you can engage these two modulation module respectively, either turning
only one module or both modules on to create unique modulation effect.
When only engaging one module, the knobs on control panel control the current module.
When engaging both module, knobs on control panel controls module 1 (time-based module).
Tweak 1 & 2 also represent different parameter for Module 1 and Module 2:
For Module 1 (Time-based)
TWEAK 1 - Controls Feedback
TWEAK 2 - Controls Wobble speed (secondary LFO)
For Module 2 (Time-based)
TWEAK 1 - Controls Shift
TWEAK 2 - Controls Wobble speed (secondary LFO)
To understand how the detailed parameters work, see Module 1 and Module 2 section.

5. LFO

LFO (Low Frequency Oscillator) generate a slow wave signal (below 20Hz) to modulate signal
phase to create modulation effect. Each waveform provides unique characteristic of resulting
sound.
Waveform:
・ Round (Sine)
・ Triangle (Saw)
・ Pulse (Square)
