[
Audio
]: This is the audio output of the filter. It can be connected to another filter (for a
serial filter connection) or directly to a VCA input.
9.1.1.2.3
CS-80 filter
This filter is an emulated version of filter found on the Yamaha CS-80 synthesizer. Like the
oscillators, the filter has a very natural sound. Where using this module, Origin is capable of
generating the analog strings, brass and pads the CS-80 was famous for, while weighing only a
fraction of the original synth. The CS-80 has been used by for example: Vangelis, Stevie Wonder,
Brian Eno, Peter Gabriel and Daft Punk.
NOTE:
The original CS-80 synthesizer used a serial HPF and LPF configuration for a very unique
sound result. Depending on the cut-off frequencies of both filters, this configuration allows you to
get a band pass filter effect. You can get this sound result on Origin by connecting two CS-80
filters modules in series. Choose a high pass filter on the first and a low pass filter on the second
filter.

The Type:
The selection box under the Frequency slider selects the type of filter. It offers you 2 types, both
have a 12dB/Oct slope :
-
[
LPF
] (Low pass filter). This filter progressively attenuates frequencies above the cut-off
frequency.
-
[
HPF
] (High pass filter). This filter acts as the inverse of a low pass filter. It progressively
attenuates frequencies below the cut-off frequency.
•
The Input connections:
-
[
Audio
]: This is the audio input of the filter. You can connect the output of an oscillator
or a mixer if you use several oscillators (or other audio modules).
-
[
FM
]: The FM modulation allows you to modulate the cutoff frequency of the filter. The
envelope or LFO are the most common modules to modulate the cutoff frequency. The
result is interesting for filter sweeps or “wah-wah” like sonorities.
-
The
Amount
knob allows you to set the depth of the selected modulation.
-
The
Bi
polar or
Un
ipolar selector allows you to set the polarity of the selected modulation.
