Waveform
LFO 1 allows you to select different waveforms for modulating parameters.
These are (from the top down):
Destination
The available LFO Destinations are as follows:
Rate
The Rate knob controls the LFO’s frequency. Turn clockwise for a faster
modulation rate.
Amount
This parameter determines to what degree the selected parameter destina-
tion will be affected by the LFO. Raising this knob’s value creates more dras-
tic results.
Play Parameters
This section deals with two things: Parameters that are affected by how you
play, and modulation that can be applied manually with standard MIDI key-
board controls.
These are:
• Velocity Control
• Pitch Bend and Modulation Wheel
• Legato
• Portamento
• Polyphony
• Voice Spread
• External Controllers
Velocity Control
Velocity is used to control various parameters according to how hard or soft
you play notes on your keyboard. A common application of velocity is to
make sounds brighter and louder if you strike the key harder. By using the
knobs in this section, you can control how much the various parameters will
be affected by velocity. The velocity sensitivity amount can be set to either
positive or negative values, with the center position representing no velocity
control.

Description
Triangle This is a smooth waveform, suitable for normal vibrato.
Inverted
Sawtooth
This produces a “ramp up” cycle. If applied to an oscillator’s
frequency, the pitch would sweep up to a set point (gov-
erned by the Amount setting), after which the cycle immedi-
ately starts over.
Sawtooth This produces a “ramp down” cycle, the same as above but
inverted.
Square This produces cycles that abruptly changes between two
values, usable for trills etc.
Random Produces random stepped modulation to the destination.
Some vintage analog synths called this feature “sample &
hold”.
Soft Random The same as above, but with smooth modulation.

Description
Osc Selecting this makes LFO control the pitch (frequency) of the
sample patch.
Filter Selecting this makes the LFO control the filter frequency.
Pan Selecting this makes the LFO modulate the pan position of
samples, i.e. it will move the sound from left to right in the
stereo field.
