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."
"This track is using sounds only from the iconic analog behemoth Sequential Circuits Prophet-10 synthesizer from the 1980.
The track is called A Day Off With The Prophet"
"I need to learn SMD soldering so I picked up a PCB and parts for the classic eurorack digital oscillator, mutable instruments' Braids by Emilie Gillet. This version has been superseded in some ways by Plaits but I quite like the look of this one regardless.
I tried out a couple different soldering techniques including classic tack-and-place with the iron and lead-free solder paste with a hot air station. The paste wasn't super easy but maybe leaded paste is better for DIY work. Along the way I fried a couple components and had to troubleshoot so I tried to give some insight into how I track that stuff down and fix it.
The module sounds great! I needed to upgrade my case power supply after this build but that's massively improved with a separate digital power rail.

"Another jam in the style of my favourite electronic group. GRP R24 sequences Arturia Minibrute 2S. Jasper Wasp clone, Mellotron Micro, Korg Microsampler, Waldorf Sreichfett, Korg Triton Extreme, CR8000 drums, Mutant bass and snare."

"The Syntecno T303 was the first version of the famous TeeBee and is a very accurate clone of the Roland TB-303. I own two TB-303’s and can use them interchangeably. The T303 also features 4 CV outputs, 4 Gate outputs, and DIN Sync for controlling other analog gear."
"A lovely CS-50, fully functioning. Last serviced in 2016. Comes with original legs and case(not pictured). Some minor scuffs but in overall good condition."
"The OB-Xa is a massive analog synthesizer with a very familiar and classic Oberheim sound. Its sound, size and power are very similar to the from Sequential. However this one has up to 8 voices which can be split, layered and stored!
The OB-Xa was available in four, six or eight voice polyphonic models. They all featured patch memories, also in varying degrees. A minimum of 32 patches were available on early models (4 banks of 8). The maximum amount of patch memory storage found on many OB-Xa's is 120 patch memories. All models of OB-Xa, however, featured the new Curtis chips which offered great stability for an analog synth and they are attributed to its great filters and sounds."
"The Titan of polyphonic analogue synthesisers. The Jupiter 8 is the golden child of Roland's legacy in professional electronic instruments, featuring 16 analogue oscillators at 2 per voice, eight voice polyphony, split-able 61 key keyboard, 2-pole (12 dB/oct) or 4-pole (24 dB/oct) filter modes, and 64 patch presets that can store keyboard splits, arpeggiator settings, voice assign mode, hold, portamento and modulation settings.
Made in Japan. Excellent condition given the age, this unit has the 14-bit D/A converter, which offers increased resolution of the CV voltages that control the analogue circuitry. Fully serviced prior to sale. Includes the original Stamford hard shell case."
"Brilliant synth, as long as you don't expect it to be an OB-XA.....Instead, it has to be considered for what it is: a Virtual Analog with a whole lot of possibilities. Strong points are it's pads, basses and particularly it's weirdo sounds. Viscount have really good VA technonlogy, just look at their organs and more recently their acoustic and electric piano simulations. Real-time performance accessoiries are great: phrase recorder, arp, motion recorder and the ribbon controller which alows you to control 2 parameters at a time. Important: the hold function of the ribbon controller actually works on this instrument. Most OB-12's have a none working hold function.
This synth got a lot of negative critics and opinions when it came out, because people expected an Oberheim OB series...which it isn't. It has a personality of it's own, very organic and that is why they are starting to be highly thought of. It is, IMHO, also one of the most beautiful synths ever made. Moreover, there were not a lot of them manufactured..."
"Absolute beast of a synth, with plenty off cv patch points. Includes original packaging, along with patch cables, power supply, and I'm throwing in the Moog CP-3 Expression Pedal, for hands free CV control."
"The drone note is a plucked ukulele string (captured by a piezo pickup into Ears module) which I stored in Clouds buffer. The pitch of the note is modulated by Marbles X section. I have manually tuned the pitch of Basimilus Iteritas Alter to get a bass note, triggered by Marbles t2 (no random skipping beats).
Marbles is receiving the clock from Pamela's New Workout.
I don't have any VCA modules yet so I've used the Dry/Wet blend knob on Clouds to balance the levels of the drone and the bass.
A very simple patch, but quite relaxing and hypnotic imo."
