LFO Env Mode

In addition to their standard function as
low frequency oscillators, LFO 1 and 2
can also serve as additional, albeit sim-
ple, 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 CONTOUR. 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 wave-
form, you will end up with an ascending
phase (attack) and a descending phase
(decay). The LFO CONTOUR parameter
also lets you determine the relative rates
of the attack and decay phases. The
absolute rate of the envelope is deter-
mined with the LFO RATE knob.
