LFOS
LFO Env Mode
In addition to their standard func-
tion as low frequency oscillators,
LFO 1 and 2 can also serve as addi-
tional, albeit simple, envelopes.
When you activate ENV mode, the
selected LFO waveform will cycle
through just once when you play a
note. This lets you use a sawtooth
wave to create a ramp, the shape
of which you can vary from linear
to exponential by means of LFO
Curve in the LFO EDIT menu. The
polarity of the respective
AMOUNTs determines if you end
up with an ascending or a
descending ramp. If, on the other
hand, you choose a triangle for
your waveform, you will end up
with an ascending phase (attack)
and a descending phase (decay).
The LFO Curve parameter also lets
you determine the relative rates of
the attack and decay phases. The

LFO Mode
LFO Mode
You can set the LFO Mode parame-
ter so that the LFOs are polyphonic
or monophonic. In Poly 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
