Zlob SVF Demo Video - Making a full track with one filter
Published on Mar 11, 2020 Synth Diy Guy
"Taking the Zlob SVF filter for a spin, I overdub 5 voices all made with this sweet gnarly beast :)"
"The SVF is a 2 pole 12dB state variable filter providing low pass, band pass, and high pass outs. The filter has 2 audio inputs, but channel 2 is jumper selectable between standard audio in or Ping-able operation. The 2019 revision also adds improved cutoff and resonance response and attenuversion to the ENV in(CV in) through the above CV pot. The 1V in provides another un-attenuated exponential approximated CV in. Contrary to what the panel says the filter does not track 1V per octave and is not temperature compensated.
At the 1V in, +10v will open the filter completely if the cutoff pot is CCW(counter clockwise). With the cutoff knob at noon the filter can be opened with +5v or closed with -5v. CV input at the ENV in is dependent on the CV attenuverter knob.
There are also several jumper selectable modes for max resonance, self oscillation or no oscillation based on the setting of the resonance pot. According to the jumper configuration, the filter is capable of clinical and clean, to juicy and drippy, to low pass gate sounding plonks, to screaming chaotic resonance. When set to self oscillation mode, the filter can produce a sine like wave with no input and a trapezoid like wave in the max resonance jumper setting. In max resonance mode, the filter output can exceed 10Vpp. On the newest version, there is a trimmer on the top pcb to set the lowest cutoff frequency.

"SoundForce is announcing the release of the SFC-5 V2 MIDI controller. The SFC-5 is a boutique MIDI controller for Prophet-5 virtual instruments such as the Arturia Prophet V and the U-he Repro-5. The 2020 V2 model offers fantastic upgrades compared to the original V1 model: 100% sheet metal case, wobble-free metal shaft pots and walnut side panels.
"This last unit available bought directly from Ken Macbeth in November 2019 from private collection.
Description of synth from Sneiders Laden:
... the Black Elements features a classical, subtractive signal flow. A closer look then reveals some cool oddities like unconventional filter slopes, extensively equipped modulators, a band echo simulation and a spring reverb. The Elements EL-2 features a completely discrete circuit design. Its sound is creamy and fat at the same time. Thanks to NOS components, the instrument has a nice vintage vibe. Compared to its predecessor, the EL-2 offers some very useful additions. – Especially its three oscillators have been extended considerably.
The outstanding synth has 3 VCOs, a tape echo simulator, a filter/resonator combination, a spring reverb, and really large modulation potentiomenters. Also the sound is huge but what really stands out (optically) is the golden touch keyboard with quick response.
The Elements has a CV and gate input socklet pair, several CV inputs, e.g. for separate VCO control, filter cutoff and for the VCA. A spring reverb line in/out socket is installed as well.
"Use the Organelle M in your MIDI setup! Send or receive MIDI over TRS and USB. Send MIDI sync, MIDI notes, and MIDI CC messages. Organelle M uses MIDI-TRS Type A cable, so be sure to use the corresponding adapter when connecting to instruments that use standard 5-pin MIDI jacks. Set the MIDI device, input/output channels, and enable/disable in the MIDI menu in the Organelle’s settings. Connect a USB-MIDI keyboard for a different range of playable notes and velocity control. Class-compliant MIDI-USB devices will work with Organelle. Use a DAW or other MIDI software to send control data."
