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 Instruments Katla #2 | Winterdagen

video upload by Winterdagen

"Here's another patch on the gorgeous ‪@genkiinstruments‬ Katla synthesizer.

For this keys patch I made use of Katla's voice rotation, with one of 5 voices tuned an octave higher than the rest, resulting in unpredictable pitch jumps in the melody, which I love. I didn't make use of Katla's oscillators for this patch, in stead the sound is coming from the filter with the resonance fully up, which tracks pitch very nicely when tuned with the simple calibration mode of holding down the two filter mode knobs.

I'm a big fan of these singing filter sine waves, which always feel a tiny bit unstable which makes them sound magical. To top it off I'm modulating the panning of the voices, I blended in some of Katla's lovely noise for some warble and I added some of the amazing internal reverb, which reminds me a bit of my Vongon Ultrasheer. I love this sound so much and I've never heard any other synth make it quite like this!

You don't see me playing the keys in the video, but I played this patch for hours, instant inspiration really. This melody is came out of that improvisation.

Thank you for watching!

ps. sine waves generally don't translate all that well on phone/laptop speakers, so speakers/earbuds/headphones advised.

Katla is shipping as of this week, find more info at: https://genki.is/"

Making Rythms from Feedback with the Zakal from Colossus Audio and the Metal Fetishist

video upload by Body Synths

"The "pairing series" is back! In this one we explore the Zakal, a spring reverb / feedback device from Colossus Audio. We start by using the Metal Fetishist as a sound source but quickly flip the tables and use it as a sound processor instead, making Rythms with the feedback tones that come through its input from the Zakal.

The background noise you may hear comes from my microphone, not from the instruments. I will be more careful next time.

https://bodysynths.com/ | https://www.colossusaudio.com/"

"Zakal is a resonant audio feedback instrument. It generates feedback using reverb springs, with the feedback signal shaped by a low-pass filter and a delay in the feedback path or simple feedback. Additionally, Zakal can function as a spring reverb effect, offering versatile sonic possibilities.

Zakal contains amplification and recovery circuits designed to generate audio feedback through its reverb springs.

A switch allows you to engage the LPF and Delay within the feedback path, enabling creative control over the frequencies fed back into the spring reverb, shaping unique resonant textures.

When used as a spring reverb effects unit, the POST EQ provides precise shaping of the wet signal, offering enhanced tonal flexibility.

At the end of the chain, a 3-band EQ provides additional shaping of the output, offering precise control over the final sound. When used as a spring reverb effects unit, the EQ enhances the wet signal for even greater tonal versatility.

ZAKAL does not include a power supply. It operates on a standard 9V DC (negative center, 2.1mm barrel plug) compatible with most guitar pedal power supplies. If you do not own one feel free to reach out, and I’ll help you find a suitable option."

Kurzweil K2061/K2088 Tutorial: Juno-60 Analog Expansion (part 1)

video upload by Kurzweil Music Systems

"In this video, we take a deep dive into the Kurzweil K2061/K2088 and explore creative V.A.S.T. programming inspired by the legendary Juno-60 sound.

This is Part 1 of a two-part series. We’ll build the patch you heard at the beginning completely from scratch, using only a single saw wave as our starting point.

Rather than recreating a vintage synth directly, this patch expands on the Juno’s classic single-oscillator architecture — demonstrating how Kurzweil’s powerful V.A.S.T. synthesis engine can transform a simple waveform into something far deeper and more expressive.

In this episode, you’ll see how to:
• Design a full synth patch from a single oscillator
• Shape tone using VAST DSP architecture
• Create movement and depth with Kurzweil FX
• Use physical controllers to add expression and performance dynamics
• Push beyond traditional analog limitations while preserving classic character

The goal is simple: show just how much is possible with one waveform, thoughtful programming, and the immense flexibility of VAST.

Featuring Kurzweil Artist Kash Iyengar.

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.
