A Guide to Synthesizer Filters (and how to use them to make music)

video upload by The Unperson

"In today's guide to synthesizer filters I break down filters and show how you can use them to make music. Whether you’re working with eurorack, hardware, software, analog, or digital synths, this guide should help you further understand filters.

We start with the basics, looking at what filters do and how low pass, high pass, and band pass filters shape sound. From there, I move into modulation, showing how to use envelopes and LFOs to add movement, rhythm, and expression to your patches.

I also cover filter self oscillation and how filters can become sound sources in their own right. Towards the end, we get into more advanced techniques like filter banks and stereo filtering to create wider, more complex sounds and mixes.

If you’re into synthesis, sound design, or electronic music production, this will give you techniques you can immediately apply to your own tracks.

Topics covered include synthesizer filters, eurorack and modular synthesis, sound design, envelopes, LFO modulation, filter self oscillation, filter banks, stereo filters, and electronic music production.

Perfect for fans of synthesis, sound design, eurorack, modular systems, and electronic music production.

New module! Dual Retro Vco

video upload by Radical Frequencies Modular

"Listen the new Radical Frequencies Dual Retro VCO playing an arpeggio , showing all waveforms and making Pulse with modulation and Hard Sync between the vcos . It goes through the RF Mixer and then to Diode Dream Vcf as it suits this oscillator perfectly! #eurorack #modularsynth #radicalfrequenciesmodular #dualretrovco #drvco #diodedreamvcf #analogsynth"

"Handmade Dual VCO of discrete core capable of internal FM cross modulations - Hard sync and Ring Modulator

• Analog discrete saw core oscillators with Saw, Pulse, Triangle and Ring Modulation wave outputs.The sound is warm and fat, emphasizing odd harmonics for this big retro sound. My purpose here is to approach the sound of classic synths from 70s, that we all loved.
• The SAW wave produces rich bass frequencies, sweet mids and smooth highs but overall, it is still well balanced across the full frequency range. The Triangle wave is almost perfect in shape with no buzzy hum sound. The pulse wave can produce that chorus-like phasing effect, when using an LFO to modulate the PWM input and does so in a very unique way, as it changes the phase of the signal as well.
• Two identical VCOs : VCO ALPHA and VCO BETA, with the ability of hard sync as each VCO syncs internally with the other. Using the attenuator knob for SYNC, you can go from zero to soft sync(11-12 o’clock) to hard sync when the knob is fully CW. For syncing you just need to turn CW, the sync knob of the VCO you want to be the slave. Don’t open both the sync knobs at the same time unless you want to make some weird sounds.
• There are external sync inputs for each VCO as well. External oscillators can be used as masters, just feed the output of the oscillator of your preference, into the sync input or either ALPHA or BETA. Just remember to feed a saw or a square wave, into the SYNC input. This is very important in order to sync the oscillator. A ramp wave it will not sync at all! (The RF DPVCO for example is a ramp out VCO and if you want to use it as master you must invert the signal first.)
• Both ALPHA and BETA track 5 octaves accurately, tempco resistors are attached to the tuning ICs CA3046 on both VCOs.
Separate voltage regulators for each oscillator can achieve the best sounding results without drift or bleed pitch, between VCOs.
• Both VCOs go from a relative fast LFO range with the coarse tuning knob fully CCW, up to high frequency oscillation.
• Octave Switches of 3 positions: 1 octave down - , zero , 1 octave up +, are available and make patching, fast and intuitive.
• There are internal normalisations for exponential as well as linear FM and both have independent EXP FM and LIN FM, attenuators.
• You can select the wave for the internal FM buss via the front panel switches .Options are Triangle and SAW. The internal FM wave, is independent per VCO as well.
• There are also internal normalisations for PWM, where each VCO modulates the pulse width, of the other and both use the triangle waveform.
• There is a PW offset, per VCO - negative phase pulse width at CCW to + positive phase at CW and 50-50 duty cycle square wave, in the middle of the knob.
• Ring Modulation section is a separate feature where X and Y inputs are internally connected with the VCOs as well. It has 2 inputs, X and Ψ and one out, RM. The inputs are internally connected to the internal FM buss switch of triangle - saw selector.
VCO ALPHA is internally connected into Ψ input and VCO BETA, into X input. You can feed the RM inputs any wave you desire from other VCOs as well .
• An external patch cable breaks the normalisation of all internal connections, via input jacks. (EXP FM, LIN FM, PWM, SYNC, X Ψ)

• Important note about tuning : The vcos need at least 30 minutes warm up before using it for good tracking. Also when you have to tune the vcos it’s better the octave switches to be in the middle position and all the fm and sync knobs must be closed (CCW)

• Large range of sounds with countless sweet spots - ultra stable tuning for FM sounds by using the FM and SYNC knobs simultaneously - fat basses, classic leads and drones. Feed the DRVCO into a good filter and you will enjoy it as it was meant to be! The VCF that I suggest is the RF Diode Dream VCF as it is a ladder filter and suits it perfectly! Of course any other filter of your taste can be used with great results."

3 Eurorack Modules That Are Complete Synth Voices (No Patching Required)

video upload by Dots

"What if you could get a complete synthesizer voice — oscillator, filter, and VCA — all in a single Eurorack module? In this video I demo three self-contained voice modules that are perfect for small racks, live performance, or anyone just getting started with modular synthesis.

I cover:
🔹 Frequency Central Product – pure analog, East Coast character, pre-patched and ready to play
🔹 Knobula Monumatic – 8-voice polyphonic (!), built-in reverb, huge sound in minimal HP
🔹 Mutable Instruments Plaits – 24 algorithms, incredible sound variety, my go-to for live performance

Whether you're new to Eurorack and don't know where to start, or you're deep in the rabbit hole and protective of your HP, these modules prove you don't need a massive rack to make great sounds.

2 Solenoids, A Snare Drum and a Ratcheted Sequence with Maths

video upload by Izhar Ashdot Sound & Vision

"These days of war take me back to the modular—its randomness, its sense of probability, and the inspiration it provides.
It’s also an opportunity to dive deeper into some of the more complex modules and really learn them.

A ratcheting exercise with Maths led to a lovely sequence that called for live drums—and that was my cue to return to my solenoids.

At the beginning of the video, you’ll hear the raw sound of the snare in the room, followed by the recorded version of it in the context of the track.

Happy to answer any questions."

Compression & Dynamics Patching on Eurorack Modular Synths // Sump Pump by Robots Are Red

video upload by DivKid

"Here we have SUMP PUMP from Robots Are Red (with circuit design from Setonix Synth). It's a 6HP stereo Eurorack noise gate that can also invert its behaviour into a compressor and with the 'floor' control it can also be an expander. We've 3 umbrella sections in the video with compression, noise gate and sidechain ducking techniques. Check out the patches and let us know which is your favourite. There's also an exclusive run down of the dirty bass patch on / divkid"

It's a noise gate, it's a noise suppressor, it's a compressor, it's an expander, it's stereo.

The Specs and Stats:

Width: 6hp
- Attack and Release knob for envelope(s)

- Threshold for suppression/compression (0V - ~8V)

- Floor controls the amount of suppression/compression from -100dB to Unity and even up to +10dB for expanding the louds louder or make the quiets a bit louder.

- Level controls your overall output level

- Gate/Comp switch: When in "Gate" mode, whenever the input falls BELOW the threshold level, the envelope will engage towards the floor setting. When in "Comp" mode, the envelope will trigger when the input rises ABOVE the threshold setting.

-Stereo inputs and outputs. The envelope follower is assigned to the Left input, so the L input can also be used as a sidechain input for a mono signal (into In-R).

- Engage input. This is a gate input for manually engaging the envelope.

- Threshold CV input. This offsets from your knob position.

- Floor CV input. This also offsets from your knob position.

- Duck CV Input. This is an envelope follower input that applies and inverted envelope to the level of the signal. Send a simple pulse or trigger, an actual kick, an envelope, or anything else into this to duck your signal.

-Envelope Output. The envelope Output does not follow the "floor" settings and always outputs a full voltage envelope.

Special thanks to SetonixSynth and many others for really helping make this module a reality.

Kaona Sisyphus V2: Experimental Textures

video upload by Kaona Modular Music

"Quelques variations expérimentales autour des nouvelles patterns de Sisyphus. Nous avons rendu la version 2 beaucoup plus malléable en traquant les glitchs, les craquements et les auto-oscillations les plus violentes. En revanche, nous avons conservé, et même renforcé, tout ce qui faisait de Sisyphus un instrument de recherche et d’expérimentation pour toutes les musiques, même les plus expérimentales !
Plus d'informations ici :
https://www.kaona.fr/index.php/fr/pro...

A few experimental variations around the new Sisyphus patterns. We made version 2 much more flexible by hunting down glitches, crackles, and the most violent self-oscillations. At the same time, we kept — and even enhanced — everything that made Sisyphus an instrument for research and experimentation across all kinds of music, even the most experimental.

Creating wavetables and Morphagene reels with Gemini 3 and Google Colab.

video upload by Cinematic Laboratory

"When I asked Gemini 3 if it could create wavetables, a new world opened up. Now, I am aware it's about artificial intelligence taking over the wonderful job of creating wavetables by hand (64 cycles of 256 bytes) I'd rather make music and noise with them. In this workflow, you'd describe what kind of 'morph' or 'animation' you'd want, and Gemini 3 would write the code in the Python programming language.

Next question is obviously: how do I run it because we don't want code, we want a WAV file in WaveEdit format. It turned out to be just a matter of pasting the code in Google's Co-laboratory (COLAB) environment and press 'play'. Then COLAB would run the code and output a .WAV with a pre-coded descriptive name. So next is to install them on your VCO of choice, which hopefully has an SD card or USB 'disk mode'.

But then the real fun begins. You can also ask Gemini 3 to code a 48K/32 bit Morphagene reel with a splice marker for every wave. These waves can be much longer, much more complex, and they can be stereo. You can create wobbles, sweeps, morphs, ticks, hiss, grains, anything. And then you can take your files to the modular, disconnect from the internet and lock the doors."

A Tiny Techno Modular using Disting NT: Suggested Systems 9

video upload by mylarmelodies

"The good folks behind Expert Sleepers hired me to make a video showing the Disting NT doing something interesting - but what that was, was up to me. I figured the NT should be able to power an entire small live system, replacing a boatload of modules in one. And I thought about how James Holden blends computers & analogue filters in his work. And so I built a live system that does just that. Here's it working, how it works, the challenges I had, and the solutions. NOTE: YOU CAN DOWNLOAD THIS DISTING NT PATCH BELOW FOR FREE"
