The Queen of Industrial Grunge Got an Upgrade — Sophisticated Dirt!

video upload by Cinematic Laboratory

"#Elmyra2 v2.4 — What’s New and Improved Sound Engine

Higher sample rate and improved wavetable resolution → noticeably cleaner top end. New wavetables added. Overall mix saturation refined, with “soft” (122) now default. Knob value stability and tuning precision improved.

Filters
New comb filter (codes 3321/3322). RESO = damping, CUTOFF = delay time, with optional pitch tracking. Ladder filter reworked — now true multimode (LP/BP/HP) with higher quality. Ladder LP (331) is the new default filter. State-variable filter retains LP/BP/HP modes (341–343) but with improved gain staging, resonance, and cutoff ranges.

Delay & Reverb
Delay fully re-implemented → cleaner feedback, no lock-ups.
Added proper reverb engine controllable with delay knobs.
Code 441 = delay (default), 442 = new reverb, 4411 = legacy lo-fi reverb.
TIME = decay, FDBK = color, MIX = blend.
Dry/wet crossfade curve improved for smoother transitions.

Modulation
New MODP: oscillator hard-sync (orange LED, position 5).
MOD controls the synced oscillator pitch.
LFO1 knob-motion recording (code 2413) — record live movement of LFO rate. Sequencer output to LFO1 possible (243v).
Per-voice sequencer clock divider (11sv).
Digitally controlled envelopes in multiple short modes (221v → very short … 224v → disable). Detune MODP range expanded.

Scales & Chromatic Mode
New musical scales for chromatic mode: major, minor, major pentatonic, minor pentatonic (CHRM + 11–14). Scale selection now unified under the CHRM button. Knob-to-pitch mapping in chromatic mode is now linear and exact.

User Interface & Workflow

LED feedback overhaul — REC and PLAY flash to confirm code entry, sequence record, mute, and drone states. Quick mute/unmute voice (MODP + PG long press). Quick octave switch (MODP + double-tap PG).
Pink MODP LED at startup identifies firmware 2.4.
Touchpad LEDs more reliable during operation.
Drone and mute response feels snappier.

Under-the-hood Fixes
State-variable filter crash fixed (previously triggered by fast cutoff modulation).
Improved detune, filter, and delay behaviors under modulation load.
Sequencer timing more consistent with internal clock."

Black Corp Kijimi MK2 sound exploration no talking

video upload by Ken Flux Pierce Fluxwithit

"Kijimi MK2 has landed in the studio and I am enjoying exploring its capabilities, quirks and raw analog sounds. This video is a no talking pretty raw exploration. exploring modulation and creating custom presets. All sounds were created from INIT to give a fresh slate.

Kijimi MK 2 is an 8 voice analog synth inspired by the RSF Polykobal from Black Corp's website

DEEP 8-VOICE ARCHITECTURE
Each of KIJIMI ’s 8 voices features 2 analog oscillators each with a square sub-bass oscillator, for buttery timbres with extensive sound design options. The sub-oscillator produces an octave lower than the combined VCO1 and VCO2 outputs, meaning you can tune two sub-pitches. Hard sync is available in VCO sync and VCO1-2 and 2-1 configurations for maximum flexibility. There’s also a noise source for adding bite and percussion components. A rich lowpass filter is built around the legendary 2140 chip and the ability to frequency-modulate it via VCO2, creates a full range of sounds from metallic and aggressive to subtle. Both filter cutoff and resonance are available as modulation destinations."

An incredible collection of more than 450 artifacts from the life and career of Florian Schneider, co-founder of the pioneer electronic band Kraftwerk."

Pics and videos featuring some of the gear below, and his Lederhosen for good measure (thanks greg!).

Update: the post has been fully updated with all the synth related gear. This may just well be the longest post to be featured on the site. I wanted to capture all the pics for all of the details including notes, scuffs, and of course serial numbers. It's an interesting look into what he used, the condition he keped his gear, in some cases, how he actually used his gear. Note the phonetics on the keys of the Casio CZ-101 and DX-100. Note the Midi Switch Box with a built-in speaker? What's that about? Note the camouflage key strap on the Korg RK-100 Remote Keyboard. Did he pick it out himself or did the keytar just come with it? Note the repeat midi controllers and the MIDI saxaphones. Wind was his primary instrument. You'll find a ton of the acoustic gear he used in the other listings. This is a fascinating insight into both what and how he used his gear.

Rack Mount Sennheiser VSM-201 Vocoder

Starting Bid $5,000

Estimate $20,000 - $40,000 USD

A late 1970s Sennheiser VSM 201 Vocoder with no serial number from the personal studio and collection of Florian Schneider of Kraftwerk (see images). While it’s said that only a few dozen of these Vocoders were produced, a few examples made it into the hands of forward-thinking musical artists including Herbie Hancock, Daft Punk, and of course, Kraftwerk, who used a VSM-201 like this on their albums Man Machine (1978) and Computerworld (1981). The VSM-201 has an intelligible sound that has not yet been bested by modern gear. Includes power cable. This VSM-201 has been removed from its wooden enclosure (which bears the serial number plate) and modified with a metal rack mount casing, presumably for live use. Requires 240v, IEC power cable not included.

Dimensions: 19 x 9 x 9 inches

A "Little Synth" Designed by Legends

Crumar S.P.A., based in Castelfidardo, Italy, was a notable player in the 1970s musical instrument industry, specializing in home organs, digital pianos, and multi-sound keyboards, and with a significant focus on the U.S. market. Sante Crucianelli, the son of the owner, became the driving force behind Crumar's design and strategies. Crumar became known for its open lab culture, frequently allowing competitors to test instruments, a rare practice for the time. Another key figure during this period was Luciano Jura, a designer, musician, and programmer. Luciano became crucial as Crumar's point of contact with synth pioneer Bob Moog, which led to a collaboration that resulted in the creation of Crumar's Spirit synthesizer.

Although many details have been lost due to the passing of key figures and the closure of Crumar, the development of the Spirit synthesizer in the U.S. is well documented. Key contributors to the project, codenamed "Little Synth," included Moog engineer Jim Scott, Moog clinician and electronic music historian Tom Rhea, and Bob Moog himself. The project likely began around 1980 or 1981, and incorporated elements from earlier projects by Scott and Moog. Rhea played an essential role in defining the Spirit's key features, such as the keyboard scanning setup, panel layout, functional architecture, and technical documentation. The Crumar Spirit went into production and was released in late 1983.

"This and other great modules are available at https://www.infinitemachinery.com/

Also, there will be a booth at Knobcon next month https://www.knobcon.com/"

"The TZ Dual VCO is two full featured VCOs on in a single 16HP module. Both VCOs output sine, square, saw, triangle and PWM wave forms. Each VCO also has thru-zero and expotential FM input. The type of FM is selectable using a toggle switch. An important feature of TZ Dual VCO is the FM input for each VCO can be control by a VCA input. A potentiometer adjusts the overall maximum of the FM input while the VCA provides an amplitude envelope.

Each VCO has the following inputs:

1V/Oct
PWM CV

"The Take 5 and Teo-5 from Sequential and Oberheim make fantastic desktop units. They feel like they were made for this form factor - no compromises, simply great sounding synths in a high quality enclosure. The keyboard versions may have felt lacking in keys (even though they have a great keybed) - just a bit too short for some. I found it was quite handy having one that could fit on my rack! But with these the only decision you have to make is which one is best for you.

Luckily I'm here to confuse you further (they both sound great)! The decision will be whether you prefer the Oberheim or Sequential style of VCO programming, the filters, and the X-Mod/FM. And these just so happen to be the bits I look at in this :)"

Adamsynths Warthog Update & Q&A

via Adamsynths

"Earlier this year at Superbooth, Adamsynths unveiled the Warthog: our total recall analog modular synthesizer.

We had tons of interest and loads of great questions from you — and now we’d love to answer some of the most common ones right here.

Is the Warthog a pre-assembled desktop synth, or a fully modular one I can customize?

Great question! The Warthog is a true plug-and-play analog modular synth. You can choose the modules you want, arrange them how you like, and build a setup that suits your workflow perfectly.

Can I use modules from other manufacturers in the Warthog?

Absolutely. The Warthog case supports standard Eurorack power. Just keep in mind: the RECALL feature only works with official Warthog modules.

Can I put Warthog modules into my existing Eurorack case?

Yes, you can — BUT. Because of the RECALL feature, the Warthog uses a different power and communication system than the usual 16-pin ribbon cable found in most Eurorack setups. That said, we’ll make sure all Warthog modules (and any necessary accessories) are also available separately, without the case.

Can I use Warthog modules together with my current modular system?

Of course! The Warthog fully follows Eurorack standards for all signal connections. It uses the same V/OCT control, and its GATE, TRIG, SYNC inputs and outputs are 5V compatible. Just a reminder: RECALL functionality only works with Warthog modules.

Why are some outputs on the CENTRAL UNIT labeled “D” for digital?

We know this caused a bit of confusion at Superbooth 25. Here’s the deal: all CV outputs are fully analog and operate in ranges like -5V to +5V or 0V to +10V. The “D” outputs — short for “digital” — are used for GATE, TRIG, SYNC, START/STOP, or RESET signals. We call them digital simply because they have two states: ON or OFF, i.e., 0 or 1.

When will we get more detailed info about the Warthog’s specs?

We are working on it! The full technical documentation will be available on our website soon. We will notify you in a newsletter as soon as it is available.

And the big one — when can I pre-order the Warthog and how much will it cost?

Right now, our team is working hard to finalize pricing and prepare for production. There’s still some groundwork to cover, but we’re doing our best every day to get the Warthog into your hands as soon as possible. Hopefully, we’ll be able to share more very soon."

Introducing Pip Filter & Pip LFO by ALM

video upload by ALM TV

"The 'Pip Filter' is a compact 4HP voltage controlled 2 pole low-pass filter with resonance and built in VCA. Here we take a look at all the features of the module.

The filter cutoff is controlled via both knob control and dual CV inputs with a built in attenuverter. Resonance is manually controlled and will reach into self oscillation with rough V/Oct tracking. A trigger input allows the filter to be pinged for percussive plucked type sounds. Finally, a built in VCA (normalled open) allows for additional independent amplitude control of the filtered signal.

The “Pip Filter’ provides a classic lowpass filter sound in a small form factor with many useful features for sound sculpting."

Introducing Pip LFO

video upload by ALM TV

"The 'Pip LFO' is a compact 4HP all analogue low frequency oscillator with a wide frequency range, voltage control, numerous outputs, reset input and a VCO mode. Here we take a look at all the features of the module.

The frequency of the Pip LFO is set via a manual control and voltage control input. The module features a unipolar square wave output along with both bipolar and uni-polar triangle, saw and sine waveform outputs. When VCO mode is activated, the frequency jumps to audio range and will track V/Oct for approx 5 octaves. A reset input allows the LFO waveform cycle to be reset and produces hard sync functionality in VCO mode.

The Pip LFO’s compact design makes it easy to add a modulation source and an analogue voice into any system."

DAW: Ableton Live

This is the same setup I used on From Deep.

Backstory
I brought my TR-606 to Ramiro at Severed Machines to install a few long-desired mods: switch replacements, a louder BD via resistor change, and Robin Whittle’s Accent Trigger and post-volume individual outs. He left in a few patterns, including a breakbeat variation that really hit me. That inspired the synth parts. Next thing I knew, I was performing and recording the full track.

Recording Notes
I treat mixers as modular routers. For Alchemical, the Alice mixer’s direct outs went straight into my interface, while the Boss BX-8 worked as a submixer for overdrive and tone shaping. I panned certain tracks hard L/R into separate buses, then re-centered them on different mixer channels. I have owned many delays while the Korg units are among my favorites, the TC Nova is often a go-to for synths: it sounds great, has nice filters, tap tempo, and my favorite feature, easily accessible time divisions Protip: a buffered pedal in front helps them sound better. The Nova reverb is also very playable and has a dynamic ducking mode that helps it get out of the way, if that's what I need.

In post, I swapped the TR-606 kick for a TR-808 sample in Ableton - it just gave the track the weight it needed. There’s also a lone TR-808 clap halfway through. Other than that, what you hear is live with only some minor edits and additional processing.

The Accent Trigger mod alone is worth it - it adds great performance potential. Robin credited the fix to me, but Ramiro deserves most of the credit. Robin's individual outs (post-volume pot) offer superior performance control and gain staging flexibility compared to the more common pre-pot version."

E-mu Drumulator 8 Kits + MIDI upgrade board

"ROM switcher boards and third-party sound ROMs are nothing new as far as the E-mu Drumulator is concerned – in fact both were available while the machine was current. JL Cooper Electronics and others made 3-kit boards, and Digidesign (who later became Avid) got their start producing alternative sound ROMs for the Drumulator under their original name of Digidrums. That said, while the various alternative ROM sets are easy to come by these days, ROM switcher boards are not, and without one it’s a total pain to keep swapping chips in and out as you have to take out 8 screws on the underneath of the thing, lift off the lid, swap 5 chips over and put it all back together again.

8 Kits

I wanted a modification very much in the same style as my TR-707 ROM expansion board, with a number of kits that you can instantly switch between. As with that project, this is done without the need for any additional switches and instead uses a microcontroller to snoop on the front panel switch matrix. Kits are selected by holding down one of the bottom row of buttons marked 1-8 and pressing the ENTER button. The selection is remembered when the Drumulator is powered off too.

The Drumulator’s sounds are stored across 4x 16kB ROM chips, although they form one continuous region of memory. Thanks to this, and due to the way that they’re selected, it’s really easy to replace all four with a single large capacity chip. The 512kB flash ROM that I used can hold 8 kits worth of sounds, which works out nicely as that’s the stock sounds plus 7 of the Digidrums kits, including the famous Rock Drums kit:

Stock kit
Digidrums Alternate Drum Set 1
Digidrums Electronic Drums 1
Digidrums Electronic Drums 2
Digidrums Rock Drums
Digidrums Jazz Drums
Digidrums Latin Percussion
Digidrums African + Misc Percussion
Because each kit also has a corresponding modified program ROM (as the length of sounds, locations in memory and channel assignments are all hard-coded into the Drumulator’s firmware); the D8KM board also has an EPROM which contains the relevant OS for all 8 kits, and is connected to the Drumulator’s OS ROM socket with a ribbon cable. Fortunately the Drumulator doesn’t care if the OS ROM changes while the machine is running as long as they’re all the same version, which they are – ‘P3.00’, the final version.

MIDI

I chose also to include MIDI functionality as part of the upgrade, as most Drumulators don’t have it. E-mu did offer a retrofit, which has been cloned over the years, but it’s very basic and only does MIDI notes. The D8KM board on the other hand also offers the ability to sync the sequencer to incoming MIDI clock. Just set the Drumulator to external clock and if MIDI clock is available, it will automatically override the external clock signal and will also start and stop playback. If MIDI clock is not available the Drumulator will use the external clock signal as normal, including for the tape loading functionality."
