Live FX
RESONANCE
Press the Filter button to access the Live Efx menu.
Touching the [Expand] box opens / closes a new menu to the left of the screen with 6 sliders and a few selection
boxes. Each slider acts simultaneously on all the entries of the current Preset or Style by modifying the following
parameters:
Lfo Rate (modulation frequency)
Lfo TVF (filter modulation)
Lfo TVA (amplitude modulation)
Q (resonance)
FC (cutoff)
Release
Each graphic slider of the menu is associated (if selected/activated) to a physical volume slider as such:
Player1 (controls Lfo Rate slider)
Style (controls Lfo TVF slider)
Drum (controls Lfo TVA slider)
Bass (controls Q slider)
Chord (controls FC slider)
Lower (controls Release slider)
Using the boxes above each menu slider you can enable / disable the physical slider (by default they are all
enabled/yellow). This is useful for de selecting an un used control or to choose to use the virtual sliders on the screen
and thus maintain the physical sliders for the Arranger volume control.
The setting values of the physical slider of the control, as well the Expand condition can be saved with Custom
Startup.
In the reset boxes placed under each virtual slider, it is possible to restore every single control to its default
condition. With [Reset All], all the controls are restored at the same time.
Pressing the Save button opens a link to save the current Voice selected.
In Filter mode the modulation wheel controls the FC slider.
If the LFO rate (Slider 1) falls below the minimum value (10) it will automatically be set as Tap Lfo mode, adjusting
to the BPM of the style.
