Sometimes you may want a G-Force LFO to begin in a predetermined phase in its cycle. For example, if you use a slow tremolo maybe you'd like it to start at max level every time you use it, or if you use an auto panner maybe you'd like it to always begin at the same pan position. This is not possible with the G-Force LFOs since they appear to start in random phases, but instead you can program an ADSR to behave like an LFO. You can reset/restart the ADSR by simply muting the guitar and then resume playing.
The ADSR parameters
The Attack and Decay parameters determine the speed of the pseudo-LFO. Shorter time settings increase the LFO speed. Different values on Attack and Decay correspond to a changed Pulsewidth in a real LFO.
Sustain time, Sustain level and Release should be set to their respective min values, otherwise they too will affect speed and pulswidth. The resulting ADSR curve should look like an inverted V:

The Trig mode can be set to "loop retrig".
The Threshold level should be adjusted according the to the G-Force Input level. This must be redone if the input signal is changed.
The Link response curve
The ADSR must of course be linked to some effect parameter (e.g. level or pan) in the modifier Matrix. The LFO depth is changed by decreasing the response curve's Low and High input levels. The resulting Link response curve can be edited to get differenty LFO wave forms:
The default response curve makes the ADSR act like a triangle wave LFO:

A curve shaped like a stretched-out S with soft, gradual bends (as opposed to in the figure) and 45 degrees steep in the middle makes the ADSR act like a sine wave LFO:

A completely vertical response curve makes the ADSR act like a square wave LFO:
