D The ENV-VEL-KBD knobs affect the “X” parameter.
The parameter can be CV controlled.
D The “Gender” parameter changes the basic timbre of the vowel genera-
tion between male (low Gender settings) and female (high Gender set-
tings) voice characteristics.
Gender can also be CV controlled.
Shaper
Waveshaping is a synthesis method for transforming sounds by altering the waveform
shape, thereby introducing various types of distortion. The Shaper can radically trans-
form the sound or just add a little warmth, depending on the mode and other settings.
D The Shaper input is taken from the Filter 1 output.
You can also route other sources directly to the Shaper in the Modulation section.
D The Shaper is activated with the button in the top left corner of the sec-
tion.
D The Drive parameter sets the amount of waveshaping.
Tip: By raising the Filter 1 Drive parameter you can add even more grit and distor-
tion to the Shaper output.
D The Shaper has 9 modes, selectable with the spin controls or by clicking
in the Mode display, all which distort the waveform in various different
ways.
These modes are; Soft and Hard clip, Saturate, Sine, Bipulse, Unipulse, Peak,
Rectify and Wrap. Exactly how the various modes affect the sound depends on
many factors, and there is a slightly random element to the resulting distortion. We
recommend simply trying the different modes to hear what happens - many inter-
esting types of distortion of the original signal are guaranteed!
Amp section
The Amp (amplifier) section has two inputs (from Filter 1 & 2) and one output that is
routed to the Global section (and on to the Master Level and the Main Outputs).
D The Gain knob controls the level and the Velocity knob controls the Gain
modulation, i.e. how much velocity affects the level - positive values
means that you get higher level the faster you strike a key.
D The Pan knob controls the relative stereo position of the individual
voices.
By applying modulation to this parameter, you can make individual voices appear
in different stereo positions when you play.
LFO 1
An LFO (Low Frequency Oscillator) is used for generating cyclic modulation. A typical
example is to have an LFO modulate the pitch of an oscillator to produce vibrato, but
there are countless other applications for LFOs.
D LFO 1 will apply modulation polyphonically.
I.e. if LFO 1 modulation of a parameter is assigned, an individual LFO cycle will be
triggered for each note you play.
D You select a LFO waveform by using the spin controls beside the wave-
form display, or by clicking in the display and moving the mouse up or
down.
The following parameters are available for LFO 1:

Description
Rate This sets the frequency or rate of the LFO.
Waveform This sets the LFO waveform. Apart from standard waveforms
(sine, square etc.) there are various different random, non-linear
and stepped waveforms. The shape of the waveforms are shown
in the display, and these shapes basically reflect how a signal is
affected.
Delay This introduces a delay before the LFO modulation onset after a
note is played. Turn clockwise for longer delay.
KBD Follow This determines if (or how much) the Rate parameter is affected
by note pitch. If you turn the knob clockwise, the modulation rate
will increase the higher up on the keyboard you play.
Key Sync As explained previously, LFO 1 is polyphonic and will produce a
separate LFO cycle for each note played. If Key Sync is off, the
cycles are free running, meaning that when you play a note the
modulation may start anywhere in the LFO waveform cycle. If
Key Sync is on, the LFO cycles are reset for each note played.
Tempo sync If this is on, the Rate will be synced to the sequencer tempo.
