Explanation of Doepfer A-108 VCF8 (Softube Modular)
This is yosi from Chillout with Beats.
I have also written a review of Softube Modular, so if you are interested, please check it out as well.
The Doepfer A-108 VCF8 is a standard module included in Softube Modular.

I will try to include some information on the actual machine. (Including my memo)

Overview
Voltage control filter based on well-known
Transistor ladder filter ("Moog" ladder)
Your own external feedback path.
parameter
Frequ: Blocks the frequency of the filter.
CV2: The amount of CV2. Scales the incoming signal on the CV2 jack.
CV3: Scales the amount of CV3, the incoming signal of the CV3 jack.
Audio Level: Audio Level: Ring volume of the audio input jack.
Emph: Emphasis, this controls the amount of feedback on the filter.Also known as resonance or Q.
input
CV1: Cutoff frequency CV control, full range 1v / octave.If you want the filter to track your keyboard completely, connect your Note CV to this jack from MIDI to the CV converter module.
CV2: CV control for cutoff frequency.This jack is connected to a CV2 knob that adjusts the amount of signal from this input.
CV3: CV control for cutoff frequency.This jack is connected to a CV3 knob that scales the amount of signal from this input.
You can have multiple CVs that control the cutoff frequency, and different CV inputs will be added together within the module.
Audio In: Audio In: Insert the signal to be filtered here.An audio level knob is connected to this jack to set the volume of the incoming signal.
Feedb: This jack splits the internal feedback path from the 48 dB output via the Emphasis knob.This allows you to insert various modules into the feedback loop.For example, inserting a VCA enables voltage controlled resonance.This allows you to feed back filter outputs other than 48dB LP to get another resonant operation.
Output
BP This is the bandpass output of the filter.That is, the audio is passed only in the center.
Near the set cutoff frequency.Emphasis sets the width of the passband.
48dB LP: This is the steepest roll-off of the filter at 48dB per octave pass filter output.
24dB LP: This is 24 dB per octave low pass filter output and is often associated with "fat" American synthesizer sounds.
12dB LP:This is 12 dB per octave low pass filter output.
6dB LP: This is a 6dB lowpass filter output per octave, the steepest rolloff of the filter that has a very mild effect on the sound of the filter.
Normally, when the dB number goes up, the cutting angle becomes closer to vertical, and I think that the change when raising the resonance is strong, but in Doepfer A-108, the smaller the dB number, the stronger the change in resonance. ..
I will use the official image.
Green is 6 dB and yellow is 48 dB, but when the bottom resonance is set high, yellow has the smallest increase in resonance.On the other hand, green is the most exciting except Band Pass.
Compare listening to each filter
It is a comparison of 4 types of listening except BandPass.
It's only 6dB, but it sounds pretty good in combination with ADSR.
This is a sound that was not produced by Voltage Modular or VCV RACK.
Explanation summary of Doepfer A-108 VCF8
If this is also prepared as an effect, the filter repertoire will increase.
It's a powerful and smooth filter, so if you don't care about the CPU load, it's full of uses.
