Elements A-Filter
BP2
— 2-pole band-pass filter. Freq ranges from between 50 Hz to 10 kHz. Width controls
the width of the filter, i.e. raising Width lowers the high-pass cutoff component of the filter and
raises the low-pass cutoff respectively, around the center frequency specified by the Freq
control.
BR2
— 2-pole band-reject filter. Freq ranges from between 50 Hz to 10 kHz. Width controls
the width of the filter, i.e. raising Width lowers the low-pass cutoff component of the filter and
raises the high-pass cutoff respectively, around the center frequency specified by the Freq
control.
DJ LP/HP 2
— A classic dual 2-pole low-pass/high-pass DJ filter. When the Freq knob is
centred, the audio signal is completely dry. When turned to the left, Freq progressively
introduces a low-pass filter cutoff, which extends all the way down to 50 Hz. When turned to
the right, it does the same with a high-pass filter, which extends all the way up to 20 kHz. The
Width control has no effect.
DJ LP/HP 4
— A classic dual 4-pole low-pass/high-pass DJ filter. When the Freq knob is
centred, the audio signal is completely dry. When turned to the left, Freq progressively
introduces a low-pass filter cutoff, which extends all the way down to 50 Hz. When turned to
the right, it does the same with a high-pass filter, which extends all the way up to 20 kHz. The
Width control has no effect.
GLOBAL
Mix
—
Controls the dry/wet mix of the device.
Vol
— Controls the volume level of the device’s output, allowing you to either attenuate it or
boost it by up to 6 decibels.
REAR PANEL
As with most other devices in our Elements series, A-Filter offers two distinct types of CV
modulation—mono or stereo—depending on the parameter in question. This is a unique
implementation which truly embraces Reason’s modular concept and allows for effects which
were impossible... until now.
CV Modulation (mono)
— The CV input modulates the parameter for the left and right audio
channel in an identical manner. Essentially, the CV modulation for these parameters works
exactly like it does for any stock Reason device.
CV modulation (L/R)
— The left and right audio channels are modulated are modulated
individually. This works by connecting the left and right CV inputs for the parameter to
separate CV sources (such as the stereo CV outputs of our DS-LFO device, or indeed any
