video upload by Another Machines

"ERICA SYNTHS HEXDRUMS — TWISTING KNOBS: Raw Out-Of-Box Sound Tour 🔊⚙️🎚️

No commentary — just the machine. A fast, out-of-the-box sound tour of the Erica Synths × Hexinverter HEXDRUMS.

Listen to each of the 10 voices (two kicks, Mutant Machine, snare, clap, rimshot, open/closed hi-hats and cymbal samples) as I twist knobs and show the raw character of the engine.

Perfect for synth heads who want immediate, honest sounds straight from the unit — no effects, no processing, no talk.

Behringer Murf Box on synth (no talk)

video upload by Richard DeHove

"Behringer's BM-15M Murf Box - now renamed as the BM-15M Resonant Filter - is a clone of the Moog Moogerfooger MF-105 MuRF. I bought this pedal thinking it might be a more interesting replacement for my Boss SL-2 Slicer. Why did I want to replace the Slicer? Because the Slicer has a few things that slightly irritate me. In hindsight, a pitiful motivation since the Murf Box has an equal number of small irritating things.

First, if you bypass the effect you only get sound out of one channel. That's irritating. It's huge, the knobs are hard to read, I don't love the EQ, the way the envelope works is odd, there's no compression on the drive, and you can't adjust the LFO without an expression pedal. Not that I entirely blame Behringer, I also blame Moog since these are all present on the OG Murf. But of course all the actual blame rests with me for not being satisfied with the Boss Slicer.

Not that the Murf sounds bad. It's a rather interesting, gritty, unusual and reasonably versatile machine. I think rather my expectations were pumped up to the same artificial heights as the OG Moogerfooger reputation and prices.

Here the Murf is receiving a MIDI clock and the expression pedal is connected to the LFO rate. The volume varies a lot depending on the EQ, mix and drive settings - and seems to fade away a bit toward the end of the video - but I thought it best to keep these as-is to show real usage.

Originally I was going to do a comparison between the Murf Box and the Boss Slicer with lots of talk. But knowing that hearing me talk too much annoys some people, and that merely showing a Behringer product will guarantee a percentage of automatic dislikes, I thought it wiser to start with a plain audio demo. I'll do a comparison with the Slicer very soon (unless everyone hates this video) since I think there's a lot of overlap and interesting design contrasts between the pedals.

Bad Gear - SERUM for OLD PEOPLE

video upload by AudioPilz

"Welcome to Bad Gear, the show about the world’s most-hated audio tools. In times like these when normal people try to steer clear of questionable spending habits, true synth nerds are still stockpiling esoteric Eurorack modules, vintage restoration projects and overpriced VST plugins in a box.

Speaking of which, today we are going to talk about the Waldorf Iridium range. While young producers with an actual history of releasing music are currently benchmarking a Serum 2 torrent, these futurist top shelf instruments based on German technology seem to be the last missing piece in every middle-aged synthesist collection before their careers are destined to take off.

Eurorack formant modules - part 2

video upload by John Schussler

"I did a comparison of some formant filters a while back ( • Eurorack Formant Filter comparison [posted here] ), and since then have acquired a few more, so time for another comparison.

This one includes the 2hp vowel, which isn't actually a filter, and the Noise Engineering Fala Versio, which isn't trying to be a talk box.

So it's all formant-y, but not strictly filters

Source audio is (for the filters) an Acid Rain Chainsaw VCO. Modulation courtesy of Zadar.

Tiliqua: Synthesizing Music Synthesizers (ORConf 2024)

video upload by vk2seb

Also see Tiliqua FPGA-based synthesizer.

"Tiliqua is an open-source Eurorack module that aims to make FPGA-based audio and video synthesis more accessible.

For updates: https://www.crowdsupply.com/apfelaudi...

This is a reupload of a talk I gave on Sept 13, 2024 at ORConf in Gothenburg, Sweden. Learn more about ORConf at https://fossi-foundation.org/orconf/2024."



"Tiliqua aims to make FPGA-based audio and video synthesis accessible to everyone. The Tiliqua hardware architecture, alongside a comprehensive collection of example projects built in Python (Amaranth HDL), allows you to experiment with synthesis techniques that are out of reach of embedded microcontroller-based platforms. Think extreme oversampling for alias-free audio-rate modulation, low-latency effects, video synthesis, and high-speed USB audio.

Tiliqua can store up to 8 projects (bitstreams) simultaneously—you can switch between them at runtime without needing a PC. Out of the box, Tiliqua can be:

A video synthesizer (vectorscope display with audio-rate beam modulation)
A multichannel wavetable oscillator (1 MHz oversampling for audio-rate FM)
A high-speed 4 in/4 out USB 2.0 audio interface
A polyphonic MIDI/touch synthesizer
A multichannel diffusion delay
A multichannel pitch shifter
A MIDI/CV converter
A matrix mixer
As the project develops and with community contributions, we hope to add many more.

Tiliqua itself is modular—the FPGA core (an integrated System-on-Module in M.2 form factor) can be removed and embedded in your projects. The audio interface section can be decoupled and connected to other FPGA development platforms. Pictured above, Tiliqua contains the following key components:

Audio Interface
8 (4 in + 4 out) DC-coupled audio channels, 192 KHz / 24-bit sampling supported
Touch and proximity sensing on all 8 audio jacks (if unused)
PWM-controlled, user-programmable red/green LEDs on each audio channel
Jack insertion detection on all 8 jacks
Motherboard
Switched rotary encoder with bar graph display.
Dual USB ports:
dbg: Included RP2040-based JTAG debugger supported by openFPGAloader
usb2: USB PHY connected directly to FPGA for high-speed USB Audio support
Display output for video synthesis (maximum resolution 720/60P)
2x expansion ports for up to 24 simultaneous audio channels (PMOD-compatible)
MIDI-In jack (TRS-A standard)"

Bad Gear - Sampler of Doom

"Welcome to Bad Gear, the show about the world’s most-hated audio tools. Old people like me keep yelling at clouds that music production has become too easy: MPC s are DAW s in a box now, even if you suck at making beats, Splice got you covered and AI is capable of creating better tracks than me.

Today we are going to talk about the Boss SP-303. This iconic drum sampler from the year 2001 is the exact opposite of all these modern shenanigans: the OG Lo-Fi sound, about as much polyphony as a Mongolian throat singer and a workflow that feels like setting the skill level of Doom to Ultra Nightmare."

Bad Gear - Serum in a Box???

video upload by AudioPilz

"Welcome to Bad Gear, the show about the world's most-hated audio tools. What a time to be alive as a synth enjoyer! Ultra affordable clones of timeless classics, even the most obscure ways of sound generation are available for the price of one soul and samplers are now almost as powerful as they were in 1991.

Meanwhile, all these beautiful instruments have become basically irrelevant for actual music production and were replaced by gaming PCs with pirated copies of SERUM.

Today we are going to talk about moDWave. This family of wavetable synthesizer was introduced in 2021 and seems to be Korg’s attempt to bring the harshness of the aforementioned industry standard plugin to the hardware world. Is it SERUM in a box?

Bad Gear is MASSIVE

video upload by AudioPilz

"Welcome to Bad Gear, the show about the world's most hated audio tools.

There aren’t many software companies whose influence on electronic music is comparable to iconic hardware brands like Roland and Korg - Native Instruments is certainly one of them.

They defined the industry standard for sampling, established in-the-box modular synthesis and made using FM much too easy but today we are going to talk about Massive.

Putting this 2006 wavetable softsynth and primary ghost writer of the first three Skrillex EPs on the show is - quite literally - long overdue as, after the usual venture capitalist fustercluck and discontinuation of Absynth, it can only be a matter of months until this classic plugin stops working properly on contemporary computers.

UVI Introduces Noctua Multi-layer Instrument

Venus Theory spent a year making a free plugin...

video upload by Venus Theory

"Howdy! Today I want to talk about the project that's taken up the last year of my life that you can get right now for the low price of free thanks to my friends at UVI.
Noctua ► https://bit.ly/noctuavt"

"From the mind of Venus Theory, renowned sound designer and YouTube creator, Noctua combines the worlds of hardware synthesis and boutique effects to realize an exquisite collection of hand-built instruments, ready to create sprawling soundscapes and evolving cinematic universes, rich with detail and movement.

Dive into an incredible multi-layer instrument built on hand-crafted samples, push and pull each layer individually with discrete microtonal sequencers, transform them with custom designed single-knob effect chains, and then finalize your sound with delay, reverb, and master buss processing - all from a single, refined and highly focused tool.

All sounds in Noctua were designed, recorded and processed by Venus Theory to capture the raw and visceral world of cinematic sound design. Divided into three categories, 'Effects Box' sounds were recorded from a variety of analog and digital hardware synthesizers processed through boutique pedals and custom digital FX, while 'EMF' sounds explore EMF recordings, transformed and multi-sampled using a variety of techniques and effect chains to create usable sonic instruments, and 'Analog', as a morphable raw source, giving users a deep pool of sonic possibility and textural exploration.

Each of Noctua's 3 sound layers has been fitted with a complex, microtonal sequencer with built-in randomization and probability. From subtle modulation and detuning to complex voicing and progressions, each layer can be customized with deep sequence control to create lush movement and sonic narrative, all with clear and easy-to-use controls.

Noctua's sound sources are treatable with fully adjustable delay and reverb sends along with powerful master buss processing including overdrive, compressor, eq, and maximizer let you dial-in the perfect sound, all from within the instrument - delivering a complete toolbox for evolving, cinematic sound design.

Noctua features a custom designed selection of one-knob fx chains. Here you can quickly browse different treatments and utilize them for sonic reinforcement, or to create performance-based transformations to the overall energy and grit of your sound. Each chain was designed by Venus Theory, providing a wide range of unique characters to explore.

100 hand-crafted presets are included, professionally designed both by Venus Theory and the UVI sound design team, delivering stylish and rarified sonic tapestries, from brooding and nuanced to terrifying. Presets are fully editable, allowing you to easily adapt the ideas to suit your needs, or create your own designs from scratch."

Alessandro Cortini + MATTHS Rig Tour

video upload by sonicstate

"Alessandro Cortini played a rare UK gig last weekend, and regular Sonic TALK panelist Matt Hodson AKA MATTHS was booked in the support slot.

We figured it was a great opportunity to have them talk about their gear selection and approach to the performance.

Alessandro opted for something minimal to support his completely improvised approach, with two Make Noise Strega (these were designed in conjunction with Alessandro) and two 0-CTRL - sequencer/CV controllers, Strymon Blue Sky and Volante all into an Allen and Heath Zone 96 DJ mixer, the laptop runs Resolume visuals for the show.

http://cortini.bandcamp.com

Matths has a different approach basing his set around pre writtern material and re-voicing larger modular rig, with the Knobula Poly Cinematic for chords, 1010music Bit Box for triggering CV and gates, the Expert Sleepers ES-9 running from the laptop for triggers from Bitwig, the Soma Pulsar-23, Beatstep

Matt uses an analogue parallel compression path to give the stereo feed to front of house a more consistent polished sound.

Actually my buddy Seth suggested this. So yep I kinda lied in the title there. These synths: one of them is a lightweight new kid straight out of a box with more sassy highs, the other is a disc crushing bohemoth piece of furniture with mellow disposition. The brand new Behringer Solina in the left channel, the crusty vintage ARP/Eminent in the right channel. I replaced the ARP mains capacitors, but left all the tropical fish alone. Some of those freshwater angels are janky and cracked but still representin'. Whaddaya think? I know best synth performance ever! Talk amongst yourselves.
