6.7 LFOs 6 PRESET PARAMETERS
6.7 LFOs
The T¨ o¨ or¨ o has 2 independent LFOs that can be used for various modulation purposes.
To access the LFO parameters, press the LFO module button. If you press
the button more than once, the selection will cycle between LFO 1 and
LFO 2. The LED color indicates which LFO is selected:
LFO 1 LFO 2
In addition, the display will show the selected LFO briefly:
LFO 1 LFO 2
In normal mode, the Shape and Speed parameters can be edited via the first and second
encoder. To edit the Rise and Phase parameters, alternate mode has to be enabled via
the ALT button.
6.7.1 Shape
This parameter sets the waveform generated by the LFO.
Triangle
Ramp up, rising sawtooth
Ramp down, falling sawtooth
Square
M-shaped wave
Random steps, Sample & hold
Slew, like random but smoothed steps for
continuous output
Amplitude modulation, product of a tri-
angle wave and the other LFOs output
6.7.2 Speed
The speed parameter sets the LFO frequency. It covers a large range from 20 seconds up
to 250Hz. The lower settings can be used for very slow, nearly unnoticable movements,
whereas the faster settings allow the LFO to be used as an additional FM audio source.
