LFO MODE
You can set the LFO Mode parameter so that
the LFOs are polyphonic or monophonic. In Po-
ly mode, the LFOs of several voices have differ-
ent phase positions. This lets you create
complex modulations for pad-like sounds, and
puts an end to the sonic monotony of a "wob-
bly" monophonic LFO. In SINGLE mode, one
LFO controls several voices so that the modula-
tion will affect several voices in the same way.
This which will make the effect stand out in the
mix.

LFO TRIG PHASE
When this function is activate, the given LFO
will no longer oscillate freely; instead, it restarts
its wave cycle at the beginning of each note.
Next to the obligatory OFF position, this param-
eter has 127 further increments. These let you
chose different positions within the wave cycle
at which the LFO will start oscillating at the start
of each note.
In contrast to ENV mode (which is available in-
dependently of KEY TRIG PHASE), an LFO with
KEY TRIG PHASE will continue to oscillate once
it has been triggered. In other words, in be-
haves like a "real" LFO rather than an envelope.
This triggering option will also work when the
LFO is synced up to the master clock. This
means that synced LFOs can be triggered via
Poly≤
note-on messages. The LFO rate, however, is
still determined via the master clock and/or
MIDI clock.

EXTERNAL LFO TRIGGER
You can also trigger an LFO at any time by
means of a controller, in other words, restart its
waveform cycle via remote control. LFO1 mode
(Ctr #70), LFO2 mode (Ctr #82) and LFO3 mode
provision controllers that you can use for this
purpose. Use Parameter B 9, see the parameter
documentation ["Appendix" on page 157].
FILTER GAIN
LFO1 lets you modulate the volume of a voice.
You'll find this function under LFO1 Amount
FILT GAIN in the LFO 1 menu. We deliberately
positioned the point of modulation prior to the
filter section, so that the degree of distortion
can be modulated at the same time when you
have activated the SATURATION unit. Beyond
that, you can use fast LFO cycles to elicit brief
impulses from the oscillator signal (transients) in
order to excite resonance in the filters. In this
case, the filters will fade out freely since their
output signals are not affected by the FILT GAIN
volume modulation.
