SIDSTATION
Owners Manual

• B/H – Band pass and high pass filter combined forming a (sort of) high pass filter that lets
through frequencies lower than just high pass.
• All – All filters combined, which does provide some strange filtering yet to be understood by
the human being.
Resonance specifies the degree to which the frequencies in the region of the cut-off frequency
will be emphased. In SidStation you can set the resonance between 0-15 with the Res
parameter.
Moving the focus to the extreme right accesses the second screen:
The filter normally doesn't wrap round between open and closed. Driving the cut-off above 127
with a LFO modulation only results in a maximum value of 127. But if Wrap is activated the filter
will wrap around from highest to lowest value above 127. (Some might say this is not very
useful)
The filter envelope (Env)
The filter has it’s own envelope which is controlled by the two screens wide Env submenu:
EnvDpth controls how much the envelope affects the cut-off value. Setting EnvDpth to 0 will
leave the Envelope unused. An EnvDpth value of 127 and setting the Cut (on the main filter
screen) parameter to 0 makes the envelope span all over the cut-off range.
Att controls the filter envelope attack speed. A low value gets the envelope up to full value
quicker than a higher value.
Dec controls the filter envelope decay speed. A low value gets the envelope from full value to
sustain value quicker than a higher value.
Accessing the second screen to the right shows the remaining parameters of the envelope:
Sus controls the filter envelope sustain value. After the attack and decay phase the filter
envelope will stay at the sustain value until the key is released.
Rel controls the filter envelope release speed. After all keys are released the release phase will
begin, and the envelope value will slope down to zero.
Invert will invert the filter envelope when activated, the envelope will be subtracted from the cut-
off value rather than added.
Filter modulation (LFO)
The LFO submenu controls LFO cut-off modulation of the filter:
