When the button is alight, it means that the controller destination is receiving the LFO modu-
lation signal. How the LFO modulates the controller is reflected graphically in the fader's
movements. The amount of LFO modulation to the destinations is dictated by the lFo a
K . It controls the peak to peak amplitude of the LFO signal. If the destination is positioned

lower peak of the LFO waveform, 0 to the zero crossing of the rising ramp, +0.5 to the upper
peak, and +1 again to the zero crossing the falling ramp.
To give you more control over the shape of the LFO waveform, the c
