CLOCK
When you set it to OFF, the LFO oscillates in the normal manner, independently of the global Master
Clock (CLOCK TEMPO). When you enter a note value here, the LFO rate is synced up to the global
master clock. The length of the waveshape's cycle will then correspond to the note value that you
have entered. You can also set the rate via CLOCK TEMPO (refer to the appropriate section) or syn-
chronize it to external MIDI clock. When the LFO is synced up to the master clock, you can also
select the desired note value via the LFO RATE knob.

TRIGGER PHASE
Selects the position in the wave cycle - i.e. the phase position - at which the LFO starts oscillating in
response to the start of a note. The control range of 1 to 127 is equivalent to phase positions of 0 to
360 degrees; the value 0 switches the KEY TRIGGER function completely off so that the LFO oscil-
lates freely and appears on random phase positions at the start of a note.
KEY FOLLOW
Controls the intensity of the KEY FOLLOW function - i.e. the rate at which the LFO follows the pitch
of a played note. At a value of 0, KEY FOLLOW is deactivated. At a value of 127, the rate doubles
with each octave.

FILTER GAIN

An additional modulation destination of LFO 1. Here the input level of the filter section is modulated
(and thus the subsequent saturation level). The effect of a FILT GAIN modulation is a periodic
change in the saturation level which is linked to a corresponding tremolo (periodic change in vol-
ume). If the signal is not saturated in any manner, then the only audible result is a tremolo effect. We

Description
In polyphonic mode, each of the voices involved is assigned a dedicated
LFO. The LFOs oscillate in different phase positions for each voice. This liv-
ens up the LFO modulation.
In polyphonic mode, all voices are assigned the same LFO. This accentu-
ates the LFO modulation, making it more pronounced.
