Phase of the sun | Prophet 12 FM Phase Modulation Tine

video upload by MIDERA

"A bit dismayed by the lack of 'bite' with the Prophet 12 FM, I tried digging deeper to see what could be done with it. Just adding 'FM' and Linear FM (i.e., phase modulation) is not enough to really brighten a sine way. Here, I then added velocity as a mod source and FM as a destination... 4 times. Apparently, on the Prophet 12, you're able to modulate and modulate things more and more for the effect you want. It seems to work, so I'll take it. All 4 oscillators are active here, although Osc2 is not audible, only acting as a modulator for OSC1. All oscillators are sine waves.

Of course, it's still not quite as expressive as the SY77. The SY77 has a lot of low end yet keeps the high end sparkly. The P12 handles it ok at best.

One person suggested keeping the oscillators under 50%. I kept them around that for this video, but I still notice distortion. I'll take their advice and drop it to under 50%, hopefully that helps.

Eventide Blackhole VST for effect."

DSI Sequential PRO3 SE // Can it REPLACE ALL your MODULAR GEAR?

video upload by Dexba

"This video is my answer to that question, the question that prompted me to buy the PRO3 in the first place.

I had quite a lot of eurorack stuff around, but it was becoming more of an obsession, with all those buy sell trade try learn trade again, in an infinite loop without sign of slowing down and PEACE.

So I decided to sell all my modular gear, in order to fund this (which seems a way better value than the two premium modules I had to sell) and some other gear.

My Sequential / DSI Pro 3 already appeared on my channel before, but in a way that wasn't the one I bought it for.

So, I took my time to try to get in the same mindset I would have had while patching my eurorack system: I started from nothing, a buzzing wave, then I started "patching", modulating the OSC, the filter, the onboard FX (yeah!), assigning some stuff to the control surfaces (touch strip + mod wheel) and I tried my best with the sequencer to obtain the deep, nonsensical, evolving patches I used to make with the modular gear.

I was so happy, I reached my goal, and now I am GAS-free for eurorack stuff.

Yeah, I miss a bit the physical act of patching, but hey, that's way more practical and it comes with presets, so I can save my work to get back to it another time!

Enjoy ✨"

Sequential OB 6 Sounds

video upload by Pure Ambient Drone

"Some sounds from the Sequential OB 6 formally known as DSI or Dave Smith Instruments. This synth really brings back the old days of the 80s for me. I love this synth very much. One of my favorite synths ever simply for the sound alone! OB 6 has such a rich old classic tone to it. Its hard to get a bad sound of this synthesizer."

Zlob Introduces the VC F3DB Fixed Filter Bank Eurorack Module

What is a Fixed Filter Bank? | Chaos + Control with Zlob VC F3DBvideo upload by Sarah Belle Reid

"In this video, we explore the history of fixed filter banks in synthesizers (what they are, how they work), demonstrate some classic fixed filter bank concepts, and then dive into a series of patch examples exploring the Zlob Modular VC F3DB.

Zlob Modular's VC F3DB is a filter bank for Eurorack modular synthesizers. But it's much more than just that as well; while it can produce the clean, dry, nasal tones you might expect from a classic Moog or Buchla filter bank, it is designed to leverage feedback, clipping, and per-band envelope followers, allowing it to act as a chaotic sound source, spectral decoder, and intense distortion.

Zlob VC F3DB First Look video upload by Brett Naucke

"A first look at this fantastic new 6-Band Voltage Controlled Filterbank by Zlob Modular. Patch examples including manual filtering, drum processing, voltage controlled filter animation, 'vocoding' and some exploitations using the filterbank as a chaotic audio source. This is a GREAT filterbank capable of some very unique overdrive and distortion functions that set it apart from all other filterbanks in eurorack modular."

via Zlob Modular

"VC F3DB stands for Voltage Controlled Fixed Filter Feedback Distortion Bank. The simplest description is it’s a 16hp six band voltage controlled fixed filter bank. But with the additions of so much gain, clipping, feedback, and self-oscillation it becomes a very flexible and unique gestural sound sculpting tool capable of; graphic equalization over 6 octaves, multi-band distortion, spectral processing, crude vocoding, multi-frequency envelope following, self-modulation, and even as an instrument on its own. With no input it can be used as a pseudo chaotic “harmonic” feedback oscillator.

The filter frequencies were specifically chosen to emphasize more ambiguous and dissonant intervals. Although the frequency bands are spread out over many octaves I purposely tried to leave out “3rds” besides a major 10th at the top frequencies to even out all the dissonance below. But the frequencies aren’t exactly equal tempered, so it’s relative. The bands roughly equate to F2, B3, F#5, C6, F7, A8.

The design is based on the Moog 914 filterbank, which it borrows the frequency bands from. But this circuit uses active filters with opamps inspired by YU Synth opposed to passive cells using inductors on the original. The 88hz is a low pass -24db/oct and 7k is a high pass -24db/oct, the rest are -12db/oct band pass filters all with a Q around 4.

The hard and soft clipping circuit on the input is fairly standard which appears in many different iterations of classic guitar pedals. But it has a lot of gain and can even boost line level signals. What makes it a bit unique is the feedback on the clipping circuit which needs to be turned on by the GFB(gain feedback) switch and the amount can be controlled by the Gain FB pot which can add some fuzz/bite to the signal depending on which clipping switch is engaged or at the extremes it will self oscillate from audio rate to LFO sort of clicking range. All the clipping stages in the module are using silicon diodes.

Consult the Signal Flow Chart to the left for a rough visual breakdown of the controls,in/outs,normalizations, and optional settings for the module.

Each band can also be muted by the top toggle switches or clipped(at the VCA) by the top slide switch which makes this design a bit different than other filter banks. As well as the overall feedback section(bottom middle) takes the sum/all bands out through a VCA(controlled by the feedback pot and FB CV) back to the input gain/clip circuit. and you can also tap into this using different sends/bands to the FB In jack to break the normalization. With this extra feedback “resonance” you can get more whistley and howly filter sounds kinda like the Serge res eq, which can also go into self oscillation.

All cv ins are expecting +5v to open the VCAs(they wont respond to negative voltage), once you get closer to +8v or so it can clip the vca regardless of the gain settings or clip switches. Output amplitude in high gain settings will exceed 10vpp and can get up to 20vpp. The envelope followers tend to stay around 0-5v out, but with clip switch active they can go up to 10v.

Since this is a high gain module there can be bleed between the bands in certain configurations and situations. Also in high gain modes with higher frequencies the 2.8k and 7k bands can bleed a little with the VCAs closed.

This is a highly involved DIY all through hole project. It is a long build with 5 different pcbs to solder and assemble.

”We put a DJ filter in it” - A Supercritical Neutron Flux Filter thing

video upload by Supercritical Synthesizers

"In the yellow factory bank, there’s an oscillator character, Mean. We thought we’d put a safety switch in it. A default pole setting that could also not oscillate. We decided to put a variable width bandpass filter in the Yellow Mean 1 pole setting. In stereo of course. Resonance controls how steep it is and Mode controls the bandwidth. Effectively you can use this like a DJ filter. At first this idea was partly a joke but this character is really convenient and effective.

Here I’m doing some bleepy bloopy matchbox scale beats in the Nanoloop app on an iPhone. It’s amplified a bit with the Beads (doing some beat repeating and reverb) which is then connected to a mixer and a parallel line run through the Neutron Flux. Parallel patching is very effective with filters. Dry and processed lines are just behind their own faders."

"I had planned to buy a used Nord Drum for some time, and I found one for a very good price some days ago. I won't keep this forever. But until then, I'll explore the possibilities and make some videos. Here, I'm just switching through some presets, accompanied by the MPC One, which also adds a compressor and a bit of delay to the drum."
