FILTER 8

MULTIMODE 8-PHASE FILTER/

OSCILLATOR

INTRODUC TIO N

Representing the cutting edge in modular

analogue voltage controlled filter (VCF) design,

Filter s 8 offer more possibilities and higher

fidelity in 12 HP than ever before.

Starting from the classic OTA-style 4-pole

cascaded lowpass (LP) topology, Filter 8 features

separate LP outputs, each with their own

character. Additional filter responses are

achieved by pole mixing: 1-pole highpass, a

special band boost and notch response, phase

shifter and 4-pole bandpass. All outputs are

available simultaneously.

Key to Filter 8's performance is the innovative

resonant feedback circuit. By increasing the

resonance, all outputs will resonate at the filter

frequency, without any low frequency response

loss. At higher resonance levels, self-oscillation is

achieved, turning the module into an excellent

8-phase sine wave voltage controlled oscillator

(VCO) with temperature and switchable gain

compensation, low distortion, constant

amplitude and accurate frequency tracking over

at least octaves. At sub audio frequencies, 5 -

Filter -8 can function as an 8 output voltage

controlled slew modifier or 8-phase low

frequency oscillator (LFO).

Simultaneous exponential and linear frequency

modulation is possible, for classic FM tones or

chaotic modulation. A hold feature is also

provided, 'freezing' the output voltages manually

or under gate control. This is useful for halting

modulations, or as a sync-like effect at audio

frequencies. The dedicated ‘ping’ input allows

you to easily create crisp percussive sounds with

different timbres.

While rooted in the legacy of classic synthesisers,

Filter 8 provides a new approach to musical

signal generators and modifiers: instead of

simply a VCF, VCO, slew modifier or VCLFO, a

single analogue module can now be any of those,

and anything in between.

CONTROLS & CONNECTI ONS

1 SWITCH FREQUENCY RANGE

This switch determines over which frequency

range Filter frequency (slew 8 will operate: low

modifier/VCLFO) or audio frequency (VCF/VCO).

2 COARSE AND FINE FREQUENCY KNOBS

The filter/oscillator frequency is determined by

these knobs. In standard audio mode, with the

fine knob centred, the coarse knob has a range

of 22 Hz to 22 kHz. The fine knob’s range is 5 % of

the coarse knob (6 semitones . in audio mode)

In low frequency mode, the total range is

2.8 6 180 mHz (a period of minutes) to Hz, with

1 Hz when both knobs are centred.

3 RESONANCE KNOB

The resonance knob controls a feedback path

from the filter output back to the input, causing

the filter frequency to be emphasised. Filter 8’s

design includes an innovative resonance circuit:

by increasing this parameter, all outputs will start

to resonate at the filter frequency, without any

low frequency response loss.

At higher feedback levels, self-oscillation will be

achieved, turning the module into an excellent

8- phase sine wave VC(LF)O.

4 VOLT PER OCTAVE FM INPUT

This input is used to modulate the frequency in

an exponential fashion, with a standard 1 volt per

octave response. This enables accurate audio

pitch in filter or oscillator mode. In the low range,

the sensitivity is increased to approximately 0.66

volt per octave.

5 EXPONENTIAL FM INPUT AND KNOB

This second exponential FM input includes a

polariser knob to set the modulation depth, with

0 in the centre, +1 volt per octave maximum and

−1 volt per octave minimum in audio mode. In

low mode, the sensitivity is increased to

approximately 0.66 volt per octave.

6 LINEAR AND AC SWITCH FM INPUT KNOB,

In addition to standard exponential FM,

simultaneous linear frequency modulation is

possible as well. This form of FM is well-known for

being more ‘tonal’ in VCO mode, limiting the

perceived shift in fundamental pitch as the FM

depth is increased.

This FM input also features a polarised depth

knob. The sensitivity ranges to approximately

±7 % frequency deviation per volt.

Enable the AC switch to AC-couple the LFM

input. This rejects any DC offset very low or

frequency content that may be present in the

modulation signal, preventing a fundamental

pitch shift audio rate from appearing during

modulation.

7 RESONANCE MODULATION INPUT AND

KNOB

The resonance amount can be modulated

through this input, with +5 V corresponding to

maximum resonance. The modulation knob

range is bipolar, just like the FM inputs.

8 GAIN COMPENSATION SWITCH

By default, each output is at unity gain with

respect to the signal input . This is very useful s

when processing audio or CV. However, when

Filter 8 is used in oscillator mode, all outputs

resonate at different amplitudes. For this reason,

the with outputs are equipped gain

compensation stages , enabled using this toggle

switch. With the compensation turned on, all

output signals will have the same amplitude.

9 SIGNAL INPUTS

Connect the signal(s) to be filtered here. These

identical inputs are mixed together, which can

simplify certain patches as it often removes the

need for a separate mixer module.

Filter distort 8 can clip and with certain input

signals, especially if they are high- , level rich in

harmonics and resonance is added. This is

because all outputs are unity gain (when

compensation is disabled), and removing

harmonics can actually result in a signal’s

amplitude rising. This distortion can be used as a

deliberate sonic effect. If you prefer to avoid it

however, simply lower the amplitude(s) of the

input signal(s).

To use Filter 8 purely as an oscillator, set the

resonance to maximum and leave the input

sockets unpatched.
