FILTER FM (STYLOPHONE PATCHBOOK 2.0) - CPM DS-2 ANALOG DRONE SYNTH

video upload by Stylophone

"CPM DS-2 ANALOG DRONE SYNTH
The FILTER FM patch works by moving Drone 1’s cutoff around at audio rate.
Start by turning down Drone 1 so we can just hear Drone 2.

Pitch Link is switched on, and the pitch is set to the middle. This means any changes to the pitch in Drone 1 will also be matched in Drone 2.

The output is set to a saw wave, and we’ve got the LFO linked to pitch, with the LFO depth turned up just slightly. This means the pitch will drift around a little bit.

Resonance is turned down and the cutoff is all the way open. This means we just get the raw output from Drone 2. Turn its volume all the way up, but plug in a patch cable — we’ll need this later.

Over on Drone 1, the pitch is set to 9 o’clock. We also have a saw wave selected, but the routing switch for the LFO is set to X-Wave. This stops it from affecting the pitch.

We’ve got the cutoff set to 12 o’clock and the resonance at 3, giving us quite a big resonant peak.

Now, when we plug the output of Drone 2 into the cutoff of Drone 1, the filter is going to get moved around at audio rate.

For a more extreme sound, try turning up the pitch LFO on Drone 2.

Also, add a bit of reverb.

Ziggy is a desktop Buchla that has all the flexibility of a modular with no patching required – Demo

video upload by MusicRadar Tech

"Buchla’s Ziggy monosynth aims to bring the brand’s singular style of West Coast synthesis to a wider audience, both by dropping the price – at $999, Ziggy is a fifth of the price of the company’s Music Easel – and repackaging the sound engine in a non-modular, self-contained desktop instrument that’s intended to be more modern and accessible than its previous designs.

The format may have changed, but Ziggy still has the digitally-controlled analogue architecture of a classic Buchla: a complex oscillator with wavefolding, a modulation oscillator for FM and AM, and a low-pass gate in place of a conventional filter and VCA, inviting the kind of unconventional sound design that has earned the brand a place in the hearts of those looking for an experimental alternative to the traditional East Coast approach. What makes Ziggy different, though, are additions like browser-managed patch storage, digital effects, and extensive connectivity: alongside CV inputs for pitch, gate and modulation, you get an external audio input and 5-pin MIDI and USB-C connections, which allow for the kind of external control via the KeyStep that you can see here.

It’s fair to say that most music-makers won’t have had the chance to experiment with a Buchla before, and with Ziggy, the company is hoping to change that. While it’s clearly more approachable than a Music Easel or a Skylab, designing sounds with Ziggy will still take some getting used to, as we found out over at Buchla’s booth – but cycling through the instrument’s presets, which showcase the unique, often chaotic timbres that West Coast synthesis is known for, left us eager to dive deeper into the Buchla universe. Mission accomplished."

Morphor ECHON 6 #2 | Winterdagen

video upload by Winterdagen

"This is one of the most beautiful synth sounds I've ever heard.

For this patch on the amazing ECHON 6 synthesizer by Morphor, I'm not using its exciter/synth section at all. The sound comes from its 6 BBD delay lines feedbacking indefinitely. The fact that the people at Morphor got to make BBD delay chips track pitch this well is already wild, but how they also managed to implement the super special glide you're hearing in this patch is beyond me. It sounds so alive!

I made use of ECHON 6's super intuitive and extensive mod section to give this patch some movement; with some LFOs I'm slowly opening and closing the filter in the feedback path and moving the voices in the stereo field. I applied keytracking to the LFO speeds making sure that each voice has different movements and a different place in the stereo field. I love that you can route keytracking to anything on ECHON 6.

I did use a fair bit of Valhalla Vintage Verb for this patch as the synth doesn't have an internal reverb. A gliding patch like this really benefits from some time based effects.

Every time I sit down with ECHON 6 for a bit, a new sound that I've never made on any other synth arises, it's so cool! I've made a lot more music with it and I'm super exited to show you.

I'm off to Superbooth now, I''ll be back with a new video next week! If you happen to be at Superbooth as well and want to say hi, feel free to shoot me a message on Instagram."

Let 3 Modules Do The Talking | Rings, Beads & Marbles

video upload by Dots

"Lost my voice. So this week’s video is a little different — no talking, just patching.

Three modules. That’s it. Mutable Instruments Rings, Beads, and Marbles in a self-contained ambient patch.

Marbles outputs random pitch CV. Rings voices them. Beads processes the output. The result is something slow, spacious, and completely unscripted.

Modules used:
Mutable Instruments Marbles (random sampler)
Mutable Instruments Rings (resonator)
Mutable Instruments Beads (granular processor)"

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."

Luna is the most LOGICAL synth in the world

video upload by Oscillator Sink

"The Luna from Neutral Labs is an instrument built on binary logic.

Taking inspiration from the DIY Lunetta synths of the 70s and 80s, Luna’s core architecture is built using CMOS chips, square waves, logic gates and binary processors. Its design leads to a semi modular instrument where rhythm is just harmony slowed down. Oscillators can be clocks, and the logic gates and binary processing modules can be involved in modulation and sequencing, or as audio processors depending on how fast you work them.

Luna supplements these binary ideas with a number of additional features which take it beyond the Lunetta synths of old, like pitch quantization with multiple scales, pitch sequencing, MIDI control and digital effects, as well as a three channel output mixer with low-pass gates.

In this video I’ll go through the various fundamental sections of Luna, demonstrating how they can be used to influence the synth, both at sub-audio-rate for sequencing and modulation as well as at audio-rate as sound processors, and then move on to a few full patches to explore how everything operates together. Throughout the video I’ll scatter a few other patches of various types to give you an idea of the range of the Luna in different musical settings.

Transparency notice: Neutral Labs Kindly sent this instrument over to me for free for the purposes of making videos about it."

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/"

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.

Probability-based Transposing with PRECISION VOLTAGES, CHANCE DELAY & a Step Sequencer #eurorack

video upload by AJH Synth Official

"A sequencer patch using PRECISION VOLTAGES and CHANCE DELAY modules for probability-based transposing of steps. Also featuring sound from a single VCO and the SONIC XV filter & wave folder.

Video & Performance by @DreamsOfWires

PATCH BREAKDOWN:
A Doepfer Mini Sequencer is playing a simple 5-step sequence. The clock is from the DUAL LFO + VCA module, which is also triggering an DH-ADSR envelope generator (connected to audio VCA), and the SAMPLE HOLD & SLEW module.

Because the sequencer gates aren't being used to trigger the envelope generator, I can use them elsewhere, and on the Mini Sequencer they can be turned off per step, so instead I am sending these gates to the PRECISION VOLTAGES (Gate A). This means that whenever a gate signal is received, Precision Voltages will activate, shifting the pitch of connected VCOs by the selected amount.

To add variety to this, I am first running the gates through the CHANCE DELAY, with which I can adjust the chance/probability of the gates being passed through to the Precision Voltages, or ignored. This means that the transposed notes will only randomly occur, based on the position of the 'Chance' pot, here at 50%.

Precision Voltages is dual channel (A & B), but I'm using the combined A + B output, so that any semitone or octave changes that I make to channel B will be combined with those on channel A, which is the only channel being switched on or off by the incoming gates. This means I can transpose the whole sequence by the same selected semitone and octave values (here plus or minus 5 semitones) and still have the selected sequencer notes randomly transposing by the same interval.

As for the sound - just a single triangle wave into the SONIC XV Diode Ladder Filter, manually adding the wave folder to create a much more interesting timbre, and with the clocked SAMPLE HOLD & SLEW module randomly modulating the filter frequency, via the DUAL LFO\s built-in VCA, which is slowly modulating the level of the Sample and Hold from strong to nothing.

Mixed on a @solidstatelogic BigSix with @vermonagear DSR-3 Dual/Stereo (real) Spring Reverb. Both cases powered by the Konstant Lab StrongPWR, with small case using a Polyend Anywhere USB PSU, powered by the USB output of the StrongPWR. Clear acrylic Eurorack case by CASA Modular, Japan."
