Hi-Hat Battle: Archer's Rig, Clutch, Metalloid & Noise Plethora

video upload by Metamyther

"Rattle Battle is an in-depth, side-by-side comparison of four distinctive Eurorack hi-hat modules—Archer's Rig, Clutch, Metalloid, and Noise Plethora. Focusing on sonic character, modulation depth, metallic texture, noise generation, and real-world patching workflows, this shootout highlights how each module handles closed and open hi-hats and sculpting of metallic percussive timbres. Whether you’re building a hard-hitting techno drum voice, experimenting with noise-based percussion, or searching for the perfect hi-hat module to cut through a dense modular mix, this comparison is tailored to producers who demand hands-on hardware control, gritty sound design, and uncompromising modular performance."

RS060 Dr Böhm Dynamic 12/24 (Orla DSE): German EFF EHM

video upload by rejected synths

"Talking synths from Germany, quite a few companies come to mind: Waldorf, Doepfer or Vermona are popular ones still around and there are a lot more, some of them long gone like pioneering PPG. One company that hardly ever makes the list is Dr Böhm Organ. This might be down to the fact that Böhm weren’t exactly a company focused on synths at all but rather one that offered DIY kits for people to build themselves electronic organs.

Strictly speaking these organs were ‘synths’ too and when the 80s arrived, Böhm, just like companies like Sequential, Roland or Yamaha, started to utilize digital control and later digital synthesis in their ‘synths’ too, albeit utilizing interfaces more akin to traditional organs.

One other similarity to ‘real’ synth companies was that they also started to offer expander modules, that could be controlled by midi, expanding the variety of sounds while at the same time saving on space (no keyboard) and costs.

This is where today’s synth comes from. The Dynamic 12/24 was meant as an affordable way for Böhm’s customers of home owners and entertainers to expand their setup with some more organ but also other sounds like strings, e-pianos and some 80s-ish synth staples.

The technology used was taken from one of it’s electronic organs and while clearly trying to hide it (even going as far as filing the markings off the ICs) it was Yamaha FM Chips doing Yamaha sounding 4OP FM. The good thing is of course, that this is actually a great basis for a very wide range of sounds, especially as Böhm was kind enough to add user memory to enable creation and saving of your own patches. Also, editing can be done via midi and there are editors available too. What makes the 12/24 stand out from the crowd of 4 OP modules most though is the unique Böhm analog bucket brigade delay style ensemble effect, that ‘warms’ the FM sound.

Last but not least, the Dynamic 12/24s seem to be widely available and dirt cheap too, at least here in and around Germany. So grab one before they become cool, or anyone finds out they are actually the same as the Orla DSE, a synth that has been used by a guy that goes by the name of Richard David James…"

Wersivoice FM76 & Wersi WV30 Wersivoice Rotor/String Effect Cards

Wersivoice FM76 video upload by hi there its me

"Vintage Chorus/Vibrato from the late 70s
- demonstrated with Ableton's Operator (Sine/Squarewave)
- no effects added
- beautiful to warm up your digital synths
- also works great with guitars, vocals..."

Note the video above is not for the listing below and it actually uses a different card. See the update from Ohm Studio below. There were different versions of the PCBs used by Wersi. Read on for details.

via this auction

"These WV30 rotor/string cards are used and tested from a Wersi Arcus and are suitable for all CD range organs. Not suitable for any DX range organs."

Update: I asked Ohm Studio if this was the same model card used in his custom design. He replied: "It’s not the same pcb I use or used in the Wersivoice FM76 above (the only standalone manufactured model they made). It’s from a more recent design and uses different bucket brigade devices, Panasonic MN3004 instead of the Philips TDA1022 used in the Wersivoice, Bohm and most of the Italian string synths and organs from the late 70s on (the Farfisa effect I built was also designed around those).

Earlier ensemble fx used TCA350 BBDs like the Eminent Solina, Logan string melody, Crumar Stringman etc.

American and Japanese designs tended to use Panasonic (Roland used the MN300x a lot. Like in Juno choruses too).

I never really notice a real difference in sound between those BBDs IF the circuit is more or less similar and based on the Solinas, ie using 3x BBDs modulated by 2 lfos, one at 6hz and one at 0,6hz.

Roland ensemble fx do sound very different than the rest, but IMO it’s not because of the uses of Panasonic BBDs but because of the circuit design that is not based on the classic eminent design.

I do think however that the Bohm Phasing rotor and the Wersivoice are the lushest you can get (except, most probably for Jurgen Haible Triple Chorus, which unfortunately I never had a chance to hear. From what I've read the Bohm was a huge influence in his design).

So to make a long story short: no it’s not the same but I’m quite sure it would sound nice because it looks like it’s the classic design."

"Introducing" the DR BÖHM DIGITAL DRUMS

video upload by Vintage Audio Institute Italia

You can find additional posts featuring the Bohm Digital Drums here.

"Dr. Böhm Digital Drums in action - that's HERR DOCTOR to you thank you very much.

We love these when they work - we hate these when they don't work.
They're notoriously hard to service - this one was no exception.
It could be the most advanced auto accompaniment unit out there - change my mind in the comment section.

We thought Dr. Böhm Digital Drums could use an in-depth video of the auto accompaniment section alone.
The videos out there present this device as a "Italo Disco Machine" - when it's actually so much more.
It has 180 different auto accompaniment arrangements, and the 4 instrument voices have more than 60 individual preset sounds at your disposal.
The variety and range of stuff that comes out of this thing is really not bad - comparing it to other machines of the same era, the Solton Programmer 24 and the CRB Computerband 2000 - Dr. B comes out ridiculously more versatile.

We used almost no effects used in this video, the compositions are improvised one-takes that we came up with on the spot without preparation.

This specific machine was modified - it had six mysterious, extra potentiometers in place already when we bought it - but they weren't hooked up to anything internally - probably a botched project from the previous owner.
So we asked one of our techs to wire them up to modify the Bass, Mono 1 and 2 sections with individual volumes and the internal, on-board cut-off filter.

The result is not bad - for all types of Electro and Electronica obviously, Pop or Ambient textures for sure, even Musique Concrete-leaning experimentations.

Big thanks to Ludus Pinski here in Florence for wiring this up for us, and to Ondrej Pavelka in Prague Czechoslovakia, for sorting out the rest."

BÖHM SOLIST-S (Böhmat) Analog Groovebox 1974 | Demonstration

video upload by AnalogAudio1

"The Boehm (Dr. Böhm) Böhmat Solist-S Compact is an analog rhythm box / accompaniment from 1974 made in (western) Germany. Great analog sound! Completely analog sound generation, not programmable. But the rhythms and different arpeggios are combinable!

I played it partly with delay (right channel only) and reverb effects (Korg SDD-3000 and Lexicon MPX-500)."

This appears to be the first 1974 model featured on the site. You can find models from 1972 and 1973 in previous posts here.
