Modulation

Modulation Generator (LFO)

The LFO (Low Frequency Oscillator) is an oscillator specialized on slow fre-
quencies that are used to create cyclic repeating modulations. Its frequency
is variable, ranging from 0.05Hz to 300Hz, being divided in two switchable
ranges. The LFO allows modulating the VCF and/or VCA, each with individ-
ually adjustable intensity. The available control elements are:

RANGE

The range switch selects the LFO's frequency range:

LO/TR

low frequencies (0.05Hz-25Hz) with retrigger. Incoming trig-
ger-signals will restart the waveform (depending on the TRIG
SRC setting in the EG section). Using suited trigger settings
allow synchronizing the LFO to an external tempo. It may also
act as a simple envelope using rhythmical trigger signals with
a suited waveform selected.

LO

lower frequency range (0.05Hz-25 Hz), free oscillating LFO.

HI

higher frequency range (1Hz-300Hz), free oscillating LFO.

SPEED

This control sets the LFO speed (frequency). The available range
depends on the RANGE-setting.

WAVE

This switch selects the LFO waveform. Choices are ascending saw tooth,
descending saw tooth, rectangle, sine, Sample & Hold (random).

A distinctive feature is the waveform EG. It derives from the envelope
modulator. Use ATTACK and DECAY to shape the waveform freely. With
ATTACK set to zero and DECAY at a higher value, you will receive a
