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 
absolute rate of the envelope is 
determined with the LFO RATE 
knob.
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
