Mod Wh: LFO 1 to OSC Pitch (lower C#)
Range: -63 to +63
The LFO 1 to OSC Pitch parameter controls the degree to which the oscillator pitch (both
Osc 1 and Osc 2) is modified by LFO 1 when using the Mod wheel 2 . This function is
summed with all other oscillator pitch controls, therefore its specific effect will also depend
on the other oscillator pitch control settings. Positive values increase the modulation,
resulting in a maximum pitch change of 96 semitones, or 8 octaves. Negative values
reduce the oscillator pitch modulation by a similar maximum amount.
Mod Wh: LFO 2 to Filter Freq (lower D)
Range: -63 to +63
The LFO 2 to Filter Freq parameter controls the degree to which the filter frequency
is modified by LFO 2 when using the Mod wheel 2 . This function is summed with all
other filter frequency controls, therefore its specific effect will also depend on the other
filter frequency control settings. Positive values increase the filter frequency modulation,
negative values decrease it.
Mod Wh: Osc 2 Pitch (lower D#)
Range: -63 to +63
The Osc 2 Pitch parameter controls the degree to which the pitch of Osc 2 is modified
when using the Mod wheel 2 . This is useful for sweeping Osc 2 by a greater amount than
is possible using the Pitch wheel. Positive values increase the modulation, resulting in a
maximum pitch change of 96 semitones, or 8 octaves. Negative values reduce the oscillator
pitch modulation by a similar maximum amount.
Aftertouch: Filter Freq (lower E)
Range: -63 to +63
The Filter Freq parameter controls the degree to which the filter frequency is modified
by aftertouch (i.e., the change in filter frequency is proportional to the amount of
pressure applied to the key once it is struck). Positive values increase the filter frequency
modulation, negative values decrease it.
Aftertouch: LFO 1 to OSC Pitch (lower F)
Range: -63 to +63
The LFO 1 to OSC Pitch parameter controls the degree to which the oscillator pitch
(for both Osc 1 and Osc 2) is modified by LFO 1 when using aftertouch. This function
is summed with the other oscillator pitch controls, therefore its specific effect will
also depend on the other oscillator pitch control settings. Positive values increase the
modulation, resulting in a maximum pitch change of 95 semitones, or 8 octaves. Negative
values reduce the oscillator pitch modulation by a similar maximum amount.
Aftertouch: LFO 2 Speed (lower F#)
Range: -63 to +63
The LFO 2 Speed parameter controls the degree to which aftertouch affects LFO 2
speed. Positive values increase the speed in proportion to the amount of pressure applied
to the key. Negative values decrease the speed of LFO 2.
LFO: Keysync LFO 1 (lower G)
Range: On or Off
Setting Keysync LFO 1 to On re-starts LFO 1 at the start of the waveform every time a key
is pressed. If set to Off it is not possible to predict where the waveform will be when a key
is pressed.
LFO: Keysync LFO 2 (lower G#)
Range: On or Off
Setting Keysync LFO 2 to On re-starts LFO 2 at the start of the waveform every time a key
is pressed. If set to Off it is not possible to predict where the waveform will be when a key
is pressed.
LFO: Speed/Sync LFO 1 (lower A)
Range: SPd or Snc
This On-key function relates to the Delay/Speed switch 23 in the LFO section. When
Delay/Speed is set to Speed, it is possible to extend its function by using the Speed/
Sync On-Key function. Setting Speed/Sync LFO 1 to Speed allows the speed of LFO 1
to be controlled by the rotary control 25 . Setting it to Sync reassigns the function of this
control, and allows the speed of LFO 1 to be synchronised to an internal or external MIDI
clock, based on a sync value selected by the control 25 . Sync values are shown on the
LED display. See Sync Values table on page 19.
LFO: Speed/Sync LFO 2 (lower A#)
Range: SPd or Snc
This On-key function operates in a similar manner to LFO: Speed/Sync LFO 1 above.
LFO: Slew LFO 1 (lower B)
Range: 0 to 127
Slew has the effect of modifying the shape of the LFO 1 waveform. Sharp edges become
less sharp as the value of Slew is increased.
LFO: Slew LFO 2 (middle C)
Range: 0 to 127
This On-key function operates in a similar manner to Slew LFO 1 above, but varies the
slew for LFO 2.
Oscillator: Pitch Bend Range (upper C#)
Range: -24 to +24
The Pitch Bend Range parameter determines the maximum range (in semitones) that a
note can be raised or lowered using the Pitch wheel 2 . A maximum of two octaves can
be selected. A positive value increases the pitch of a note when the Pitch wheel is rotated
“forwards” and decrease its pitch when it is rotated “backwards”. A negative Pitch Bend
value reverses this relationship.
Oscillator: Osc 1-2 sync (upper D)
Range: Off or On
Osc 1-2 sync is a technique of using Osc 1 to add harmonics to Osc 2 by using oscillator
1’s waveform to re-trigger that of oscillator 2. When OSC 1-2 sync is On, the Sync 1-2 LED
[20] is illuminated. See page 9 for further details.
Velocity: Amp Env (upper D#)
Range: -63 to +63
This function adds touch sensitivity to overall volume, so that with positive parameter
values, the harder you play the keys, the louder will be the sound. With Amplitude
Velocity set to zero, the volume is the same regardless of how the keys are played. The
relationship between the velocity at which a note is played and volume is determined by the
value. Note that negative values have the inverse effect.
For the most “natural” playing style, try setting Amp Env to about +40.
Velocity: Mod Env (upper E)
Range: -63 to +63
As Amp Env adds touch sensitivity to volume, so Mod Env can be set to make the effect
of anything being controlled by the Modulation envelope become touch sensitive. With
positive parameter values, the harder you play the keys, the greater will be the effect of the
modulation. Note that negative values have the inverse effect.
VCA: Limiter (upper F)
Range: 0 to 127
Because Bass Station II can generate a very wide dynamic range – particularly if the filter
section is adjusted close to self-oscillation – it may be desirable to apply limiting to the
synth output to control the signal level. This On-key function applies a simple limiter (there
are no other controls) to the VCA stage. It is best adjusted after all other sound parameters
have been tweaked; if possible, set it while checking the output level on the meter of a
mixer or amplifier to ensure that no clipping occurs while any in-performance controls are
adjusted. As the parameter value is increased, the limiting becomes more severe, resulting
in a compressed sound at lower output level. You may have to turn the volume up externally
to compensate for limiting.
