Envelopes 1&2 Section - Novation Bass Station Owner's Manual

How The Controls Work How The Controls Work
Filter Section - Continued
Mod Depth - Rotary
This knob controls the amount of change to the filter cut-off set by the Frequency knob to the left.
In its central position there is no change to the filter cut-off frequency. To the left of centre there
will be an increasing amount of negative modulation, ie. the filter will be closed more and to the
right the modulation is positive, ie. the filter will be increasingly opened by the modulation sources.
The Filter Mod switch below selects which source will produce this modulation or change in the
filter cut-off frequency.
Mod Source - Switch
This switch selects whether the amount of variation in the filter cut-off frequency set by the
Modulation knob above is controlled by the LFO or by Envelope 2. If the LFO is selected then the
filter cut-off will be moved around the starting point set by the Frequency knob at a rate set by the
Speed knob in the LFO Section. The amount of movement is set by the Modulation knob above.
If Env 2 is selected then the filter cut-off will be moved away from and back to the starting point
set by the Frequency knob. If the Modulation knob is set to a negative amount, the Attack of
Envelope 2 will close the filter and the Decay/Release will re-open it back to the starting point. If
the amount is positive, the Attack will open the filter further and the Decay/Release will close it
back to its starting point. Using positive Modulation from Env 2 will emphasize the attack of the
note (especially if the Resonance is turned up), whereas LFO modulation will provide a tremolo
effect.
Cut- Off - Switch
This switch allows you to change how drastically the frequencies above the cut-off point are
removed from the sound. In the 12dB position, the cut-off slope is less steep so the higher
frequencies are not attenuated (reduced in volume) as much as they are in the 24dB position.
This makes the resulting filtering in the 12dB position more subtle than the 24dB, which you should
select if you want the cut-off to be more obvious.
Envelopes (1&2) Section
The envelopes are used to shape
the sound over time. Envelope 1
is hard-wired' to amplitude or
volume. It is used to decide how
quickly the sound starts when
you hit a note and how it
sustains or dies away. Envelope
2 can be used to control both
Pulse Width and/or Filter
Frequency changes depending
on the settings of the Mod Source
switch below Pulse Width and the Filter Mod switch in the Filter section. Of course, if neither
of these is switched to Env 2, you will hear no change when you alter the settings of
Envelope 2. Switch one or the other to Env 2 to hear the changes you are making.
Envelope 1 2 - Switch
This switch selects which envelope you are currently making changes to. If 1 is selected then
changes to the knobs in this section will change the way the amplitude or volume envelope
responds when you hit, hold and release a note. If 2 is selected, then changes to the Envelope
knobs will affect the Pulse Width and/or Filter Frequency modulation (depending on which is
switched to Env 2 in the appropriate sections). N.B. the settings of each envelope will be
unaffected until you move the appropriate knobs, as the current settings of those knobs are
ignored until they moved (otherwise each Envelope would automatically copy the settings of the
other when you switched between them.
