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.

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.

Additional SYNTH CITY Listings

"The Computone Lyricon II is a vintage electronic wind synthesizer developed in the 1970s that allows musicians to control synthesizer sounds using breath and fingerings similar to a saxophone. It converts breath pressure and key movements into electronic signals that shape pitch, volume, and expression.

Unlike earlier versions, the Lyricon II includes a built in analog synthesizer so it can generate sounds on its own. It is considered one of the earliest and most influential wind controllers, helping inspire later instruments like the Akai EWI!

Please note: it will require a replacement reed to be fully playable. Replacement reeds are available and commonly replaced as part of normal maintenance on Lyricon instruments.

This particular unit was recently serviced in house and received a clean bill of health. The instrument is functioning as intended and ready for use. Includes original carrying case and appropriate cables as shown."

Genki KATLA - THE VOLCANO SYNTH!! Now Available

video upload by Starsky Carr

"What happens when a synthesizer completely breaks the rules?
In this video, we explore the Genki KATLA — a truly unique polysynth inspired by Icelandic volcanoes, featuring a rotating voice architecture, hybrid signal path, and some of the most unpredictable sound design possibilities I’ve come across.

This isn’t your typical analog polysynth. Each of the five voices can run independently with different waveforms, octaves, and modulation — creating evolving textures, harmonic movement, and generative-style sounds that feel closer to modular synthesis than traditional keyboards.

🎛️ What makes the KATLA special?
• Rotating voice polyphony (round robin-style synthesis)
• Independent per-voice oscillators & tuning
• Digital oscillators + analog filter signal path
• Looping envelopes reaching audio-rate modulation
• Phase distortion, wavefolding & multiple distortion types
• Tape-style wow, flutter & pitch instability effects
• Stereo voice movement & evolving spatial modulation
• External inputs for processing other gear

From lush ambient pads to aggressive, evolving sequences — this synth can go places most instruments simply can’t. It’s not about recreating vintage sounds… it’s about discovering entirely new ones.

💸 At around €5000, this is definitely not a beginner synth — but for sound designers, and anyone looking for something truly different, it well worth a look."

"Hey guys! Very very excited to be presenting the Genki Katla to you all... I am truly in awe of the sound of this very unique and powerful instrument.

I thought the best way to get to know the synth is to start from scratch so in this video we'll go full hands-on with the Genki Katla, exploring (almost) every parameter and building sounds from an initialized patch.

From some raw drone layers and gritty textures to evolving pads, rhythmic sequences, and atmospheric beds, we will see just what this instrument can do, discover new sounds, and maybe make some friends along the way 🙏

If you're into sound design, unique synths, or just love discovering new instruments, this one is for you!

HUGE thanks to Genki for letting me a part of this with them and showing off this super cool synth.

No money was paid, no agreements were made... these are my real thoughts on this very premium synthesizer and I will be sharing lots more."

Press release follows:


Genki Instruments announces availability of Katla as Voice Rotating Polyphonic Synthesizer inspired by its natural namesake

REYKJAVIK, ICELAND: having twice blown European musical minds thanks to show-stealing showcases at SUPERBOOTH25, May 8-10, Berlin, Germany and Machina Bristronica 2025, September 27-28, Bristol, UK, before adventuring across the pond for a repeat performance at Buchla & Friends 2026, January 24-25, LA, CA, USA, Reykjavik-based instrument developer Genki Instruments is proud to announce availability of the eagerly-awaited Katla as a Voice Rotating Polyphonic Synthesizer inspired by Iceland’s largest subglacial volcano as its natural namesake — readily representing the company’s first foray into analogue synthesis, albeit one that uniquely utilises a set of wildcard parameters to infuse it with organic, unpredictable behaviour as an instrument that is worthy of that legacy, excelling at generating rich, evolving, multi-layered textures, where each note stirs, swells, and erupts in its own distinct way — as of March 31…

Clearly Katla’s inspiration runs through its ‘volcanic’ veins. After all, it is framed by side panels and knobs forged from authentic Icelandic lava, giving each instrument a tangible connection to the volcanic forces that inspired it. That this synth should surely roar is a given. Genki Instruments inevitably chose, therefore, to kit Katla out with four independent distortion destinations, the most unruly of which is a stereo CMOS (Complementary Metal Oxide Semiconductor) Drive effect — a characterful saturation stage, pushing tones from warm and rounded to fractured and snarling.
