"This is the highest quality DMX with MIDI you'll find. The unit shown in the photos is the one for sale now. We paid our tech for the 17 hours of highly skilled labor + parts required to make this unit better than the rest. No expense spared. No corners cut. The end result is an item that's way better than others of its type you may find and which is justifiably more expensive. Or you could buy a cheaper one and pay us a lot more to restore it for you to get it up to this ones level... if we're available for outside restoration work.
In addition to necessary repairs, here's what was done to this unit in an effort to increase reliability and keep this unit working perfectly way longer than others out there:
Full cleaning inside and out. Power supply electrolytic capacitors replaced, jumper wires, new regulator with heat sync, IC socket (16p x 2), resoldered molex connector pins. Installed new battery and diode. Replaced molex connector terminals (x40). Removed original slide pots and replaced with new ones for perfect, smooth, crackle free performance. Installed 20p IC socket x4. Cleaned and lubed switch contacts. Installed new rubber feet. Replaced a bunch of ICs (oerformance related, won't change this unit's sound). Replaced voice card molex connectors.
This unit is in beautiful shape and is ready to play and record with, no excuses or BS typical of other vintage gear deals and no, we won't sell it for what unrestored junk (or other selllers supposedly serviced gear that was done as quickly and as cheaply as possible) sells for. You get what you pay for.

"This is quite a rare tape echo manufactured by Dynacord. It seems to be one of the very last tape echo introduced by the brand (with the Echolette Echo 400).
It shares many parts with the Echocord line of delays like motor, pinch roller, heads, oscillator board etc
But this one useS op amps instead of only transistors for amp stages (the Echocord Super 76 also already used one op amp for the output stage).
The unit has 2 heads which you can mix with the dedicated pot. Otherwise classic features like input volume, tone, echo send level, echo feedback and echo level.
In the back the original DIN socket enabled output and aux input. In this case you only get the wet signal out of the delay, which is nice in a studio environment.
Unit was fully serviced and modded. [mods below]
I demoed it with 3 different instruments so you get a good idea of how it sounds with different sources. First is a Roland MC-202, analog mono synth, then an analog drum machine (Roland CR-78) and last an electric guitar (Squier Jagmaster, not in frame). Please note the SE-251 has no hi input impedance so I run the guitar through a DI Box first.
00:00 ROLAND MC202
03:18 ROLAND CR78
06:16 SQUIER JAGMASTER"
- all electrolityc caps were replaced (except 3 bipolar ones )
- original 4x op amps were upgraded to better one (TL081)
- original DIN socket was replaced by 2 jack sockets, one for the output and one for the aux input. Also a pot was added to attenuate the level for the aux input
"Rare/iconic/collectable as everyone will be aware, and sounds absolutely amazing. People say it has a distinct, different sonic character to the Minimoog. Huge bottom end, these vintage Moogs sound like raw electricity. Like you've just plugged a lead into a power socket on your wall. Crazy fat bass, searing leads, alien abduction sounds, etc etc etc.
Cosmetically in excellent condition, just serviced! I bought this from the original owner, who told me that it wasn't gigged. It's amazing example, usually the wooden panels show lots of wear and tear, but the panels on this one looks amazing."
"It’s basically one of the takes on Boss DR-55, authentically made in Japan. as far as I’m aware - these were sold as diy kits back in 80s, but functionally are identical to Boss DR-55, sound is also the same/almost the same.
please, NOTE, it’s been modified to be powered from … eurorack offset voltage.
power now is on minijack socket. you just take an offset from eurorack system, and plug it in to power the drum machine, directly, using eurorack patch cable. it will take any voltage from approx. 5v up to 12v.
it also has analogue clock output, and cymbal trigger output, so will sync with everything perfectly.
currently it won’t accept any other power sources, but it’s a very mod friendly machine! as mentioned above, they were sold as diy kits at some point, so they beg you for modifications. I believe it even can be modified to fit into eurorack housing, and it shouldn’t be hard."

"This is an absolute rarity !! This keyboard is very, very hard to find.
Extremely clean - the surface, all the keys, the switches. The real wood is still beautifully preserved, the sheet-music stand is intact with very minor scratches and the metal work is fantastic condition.
Everything works perfectly (apart from one key that works beautifully once the keyboard has warmed up!).
All sections have their own volume control and I have video of the various sections working (will provide upon request).
The automatic accompaniment-system can also be operated without the acoustic
signals being switched on acoustically. The bass sequencing will still change with the
selected rhythm - this results in quite interesting sequences ! I believe it has a memory function you only need to tap a bass-key, then it is automatically held (this also works without the automatic accompaniment). Of course, the respective rhythms can also be switched acoustically.
The keyboard has a built-in loudspeaker (at the bottom) - this works also perfectly (without distortion). On the back there is a line-out socket for an external amplifier and an output for a pedal (pedal not included).
It does have the original carry case which has no rips or tears.
Dimensions - About 82 cm wide x 19 cm high x 40 cm deep.
"Here is another "one man band" from the 70s I just serviced. Many dead CMOS chipsets, lots of bad connections on the motherboard daughterboards sockets (broken pins, bad solder joint) and a dying voltage regulator, among other things.
Custom built keyboard to trigger the accompaniment unit, with jack socket input for pedal that introduce drum breaks.
A different flavor than the Welson Ritmo I recently demoed but definitely in the same mood.
Recorded through a Teisco 120 to add some reverb."
This appears to be the first post to feature the Elka Wilgamat 1. Note the "1" on the right. The Elka Wilgamat minus the "1" has been featured on the site before in previous posts here. Which came first? :) You can find additional Elka Wilgamat models here.
Update: according to Ohm Studio: "Electronics are exactly the same. I think this one is later and was an add for some Elka organ, maybe Concorde or something. The black color is I think factory since it’s all over the case even inside. It’s clearly the same fake wood as the original but painted black, probably to better match the organ aesthetics. I definitely remember seeing auctions with Elka organ and this wilgamat unit bundle. Also the complete wilgamat electronics and controls are fitted in some Elka organ, spinet and combo. Don’t remember which model but I did scavenged à spinet one to retrieve all the pcbs."
"welcome to strange, bizarre, obscure and unknown equipment rubric.
today I’ll be introducing you this extremely rare set.
includes all three sound making machines made by Yamaha in the late 80s. (1988 approximately).
it’s a pack with very cool vintage sound and convenient features.
set includes:
• Yamaha EMT-1
8-voice poly synth. based on Yamaha famous FM chip, and using them for sound generation. this is basically like Yamaha DX-21 or something similar, having most of the most famous presets here, and allowing slight variations towards them, and lots of different multi-timbral options. also allows to control some parameters via SysEx.
• Yamaha EMT-10
8-voice polyphonic pcm based sound generation. but in a good way. sounds are multi-sampled, and sound extremely realistic, and very vintage. has slight variation options over the sounds, and few simple multi-timbral options.
• Yamaha EMR-1
digital rhythm box. has fancy preset rhythms, very reminiscent of some great tunes. also can be fully midi controlled, and each sound can be individually sequenced externally via midi.
also has this great led-display showing measures progression, and a display showing bpm and measure counter information.
very nice feature is that all three machines feature power supply in and out sockets, which means that all three can be powered just from one power adapter, and connected together using dc-dc cables.
also all three feature line out, but also Aux In. so all three can be mixed together and their outputs can be daisy chained connected, to have just one stereo pair in the end, which will produce stereo outputs of all of the three devices.
and they also can be daisy chained by midi! each features midi thru socket.
so fully daisy chainable, very well connectable vintage pack.
be special, choose something weird and unknown instead of these other boring famous things everyone else has. choose character."
"Overview The original Roland 100M (1978) has only one type of voltage controlled filter, 24dB low pass. This rather limits the range of sounds that can be created with the synthesizer and it is strange that Roland never ported the 703 2-pole OTA SVF into the 100M format. The AM8122 closes this gap and provides two 2-pole State Variable Filters in one 16HP module.
AMSynths Design The AS3320 chip is used to create the SVF, rather than the CA3080 OTA in the original 703 module. This is partly down to the limited PCB space for two filters and partly because the 3320 chip in SVF mode sounds very good, think Oberheim OBX. An alternative approach would be to build a dual Jupiter 6 SVF with AS3109’s, but this is tricky to achieve given the limited PCB space and we already produce a Jupiter 6 module – the AM8060 module.
The AM8122 circuit reuses the 2-pole SVF in the AM8325 and adds the BP mode and voltage controlled resonance. The third CV input is used as the Resonance CV input. The front panel design follows the Behringer 121 module with signal and CV input trimmers, frequency and resonance on 30mm sliders and green and red indicator LED’s.
Each filter has two outputs, with a slide switch selecting which filter output goes to which jack socket. The upper jack socket (OUT) can be set to either LP, BP or HP and the lower jack socket (REV OUT) follows the reverse (HP, BP, LP). This approach ensure the LED’s track the filter mode selected by the switch, whilst still providing individual outputs of each filter mode. The three signal inputs of the second filter are normalised to the outputs of the first filter (HP, BP and LP), so that the filter modes can be mixed together and filtered again!
Front Panels The panels use the same manufacturing process as the earlier AMSynths 100Mmodules, with a white silk screen over a dusty grey powder coated panel.
Outcome & Availability The module and panel were designed in December 2022. In 1Q23 the prototype PCB’s were debugged, with the revised LED drive and increased filter output levels so they are all the same (10V p-t-p). Production modules will be availble in 3Q23. The AM8122 will be the first AMSynths module to use SMD manufacturing processes (JLCPCB) for the PCB’s."
as hot summer months are slowly passing by, our Prague workshop has been pretty busy working on all axes. Since there's now two products to care for, there's more things to do, more PCB wiring and more code to siphon through, but there's a silver lining in that when we're too deep in one thing and need some respite, there's always something to do on the other :)
We are Beetlecrab.audio
Another thing we're slowly dealing with is the inscrutable situation about our branding, which we have gotten ourselves into. Vector, VectorSynth Tempera, TemperaSynth Vector, Vectora Synth Temper. It's a mess. To get out of all this confusion we decided to adopt an umbrella for both existing and new upcoming projects: beetlecrab.audio. We couldn't quite figure out a suitable name but many of you started using this, so let's go with it. For now the website is a simple crossroad and will be improved over time. Both Vector and Tempera newsletters will be merged into one at some point, so if you're subscribed to both you may have received this email twice. Please ignore the other.
Now to the actual news. There's two parts here -- an update about how Tempera production is going, and announcement of the new Vector v2.9.1 firmware update. Let's start with -
Tempera Production Update
New upgrades
There's a few changes made to the hardware that we're comfortable sharing, now that they are verified. First, a great quality of life improvement: the TRS MIDI sockets are compatible both with Type A and Type B wiring ! This means that you don't have to worry and fiddle with unmarked adapters -- both types will work.
Next, we were still a bit unhappy with the powder coat finish of the metal case. It's difficult to get right: each attempt at different color and paint structure takes a lot of time to test and verify because at least a piece of metal needs to be painted and sent to us for examination, and it takes even longer because of course the metal case manufacturer doesn't have all the paints in stock, and sometimes they have to buy a whole bottle just to use a few drops. A sample palette exists but as we already learned with Vector, these give some idea but in the end look nothing like what you think on the actual metal, on the bends, crevices and so on.
Having said all that, I think we found and verified a finish that we're really happy with . It's less glossy and has a finer and more granular (hah) structure. It's very nice to the touch and I think looks much better. See for yourself, how the light interacts with the old vs new powder coat on top. Noticeable are also the beautifully laser etched graphics. (Tempera in old finish, plate on top in new finish. The light is angled in such a way to highlight the grain, the new finish is in fact even blacker than the old.)

"Here is a demo of this italian 6 voice analog polysynth i'm selling (via this auction)
Unit was upgraded with the great Tauntek firmware and can now be controlled remotely over midi by Control Change with any controller.
In the demo I basically flip through the unit presets and edit some of them on the fly just to show how easy it is now to program this otherwise austere synth.
I didn't demo the bi-timbral feature of the rack. You can have 2 different presets, lower and upper, either layered ("double") or split. Lower and Upper parts can have their own audio output.
Preset from 76 to 99 are allocated for the performance presets and need to be dialed in (you can't use the + and - value switch to select those like I did on the video)."
"Italian 6 voice analog polysynth. This is the CEM 3328 version, not the SSM 2044 one, in the rare white colour.
This unit was serviced and upgraded and is in perfect working condition, see video. What was done: - power supply capacitors were replaced - new battery was installed - Tauntek new firmware eproms were installed. You can now control the unit directly over MIDI with CC with any hardware or software controller - Midi thru socket was modified so that you can export your preset by sysex dump over midi (original could only export presets through the "tape" function)
It also comes with some goodies (well especially for french speaking person) - original owner's manual + preset lists (in french) - original schematics diagram - original Crumar Bit range advertissement (in french) - original inspection card from factory (this unit came out from factory in November 1985)
Condition is very good with only minor scuffs to the nice white metal paint."
"This video is about Mort’s Barge - a replica mini-system of five Buchla 100 series modules that were used by electronic music pioneer Morton Subotnick in the mid-1960s. I recently built the 4U DIY modules from LA67, and in this video I walk through the features and create a few patches that show what they’re capable of.
Notes and pics via Tom Churchill's post on Mod Wiggler:
"I thought I’d share a couple of things I learned along the way which maybe aren’t immediately obvious from the BOMs alone, in case anyone else is planning to tackle the build and is looking for some tips.
Some of this stuff has no doubt been covered earlier in the thread, so apologies for any repetition. Also, a lot will probably be obvious to experienced builders, but I’m definitely not in that category yet, so for anyone else (like me) who’s only built Eurorack kits previously, maybe isn’t super-familiar with circuit theory and component sourcing, it might be useful.
Enclosure: After I ordered the panels and PCBs from LA67 I contacted Julian at The Beast to ask about his 6U Buchla boats. As luck would have it he still had a couple of the special boats he supplied to LA67 for the pre-built Mort’s Barge systems, with matt black coating and pre-drilled holes for power inlet, power switch and grounding banana socket, so I snagged one. I added some rubber feet to allow a bit of clearance for the screws I used to mount the PSU PCB (see below) and to avoid the underside getting scratched. For mounting the modules, I bought a pack of 20 M3 speed fasteners (aka captive nuts, aka Tinnermans) from eBay, and secured the modules using M3 6mm screws with plastic washers. Power: The PSU PCB doesn’t require any caps and you just need to solder one bridge as marked. (This is now clear on the Mort’s Barge PSU BOM, but it wasn’t at first.) I mounted the PSU PCB on 8mm M2.5 standoffs via the pre-drilled holes in the bottom of the boat. I added a 2.1.mm DC inlet and wired a 20mm round rocker switch in series. I added a single banana socket connected to 0V to provide a ground for any other cases I might want to use with it (and for connecting to Eurorack - see below). For the AC-DC converter I just used a standard 12V 2A wall wart I had lying around, with a 2.1mm centre positive barrel connector. I used the 2-pin Molex connectors as per the BOM to distribute power to the individual modules (with the power cables hard-wired to the individual module PCBs) Component sourcing: I combined the individual BOMs for the five modules into one master BOM, ticked off what I already had in stock (mostly resistors), then ordered any other required resistors, trimmers, pots, 2N3904/6 transistors and various bits of hardware from Tayda; caps, specialist transistors, diodes, switches, knobs, lamps etc from Mouser. I’m in the UK and banana sockets worked out slightly cheaper from Thonk, so I ordered those there. I also bought the necessary matched transistor pairs from Thonk to save time (I don’t have the tools or experience to match them myself!) Changes: This might be sacrilege to Buchla purists but I went for Switchcraft 3.5mm sockets instead of Tini-Jax - I already have lots of 3.5mm patch cables and it makes for easier integration. The 910p film caps on the BOM are huge - 10mm lead spacing - and expensive. I ordered them before I realised this, and with a bit of leg straightening/bending they do fit fine in the 158 and 180 boards, but I replaced them with these much smaller and cheaper 1n mylar film caps for the 140 - https://www.switchelectronics.co.uk/1nf ... apacitor-5 - and they work just fine. The BOM has since been corrected, but slightly annoyingly at the time I was ordering, the part code for the Dialight lamps in the 123 was out of date, so the ones that arrived in my original order were the wrong size. I had to do a separate order for the correct parts, 609-1122-130F. These aren’t cheap, so double check that you’re getting 9mm ones! On the 158 BOM, there’s a suggestion to use 1n5 instead of 47n for C11 to reduce saw wave distortion. I put sockets in for that and tried both - the 1n5 definitely gives a much cleaner saw so I’ve stuck with that. I also left out C8 as suggested to improve sine shape - I didn’t try it with it included but the sine is definitely a good shape without so I’ll stick without it. General tips: I built them in the left to right order they’re shown on the LA67 photos - 158, 110, 180, 140, 123. It was pretty easy to test this way. Calibration-wise there’s not much to do - the trimmers on the 158 adjust the sine shape and upper and lower frequency limits; use the 110 trimmers to minimise clicking with a raw trigger in; the 140 trimmers set the upper and lower period (I haven’t really touched these) For the wiring, I soldered pins to the PCB and used a bunch of F-F Dupont jumper wires, cut in half, so if I ever need to take the board off I can simply pull these off and don’t need to desolder anything. For the multiple outputs I mostly just used old resistor legs to bridge them. Integrating with Eurorack clock is easy - both the 180 and the 123 respond to triggers as low as 5V (e.g. from Pam’s). I don’t use a format jumbler, just a 3.5mm to two bananas cable, with the ground banana connected to the spare ground I fitted near the power switch. I don’t think I’ll ever bother trying to send CV from Eurorack but this way I can at least clock it to the rest of my system if I want to, and maybe even play around with some more complex rhythm patterns. Anyway, hope that’s handy for someone - I’ll share a bunch of patches on YouTube soon!"
"Pretty rare British-made drum machine from 1981, originally intended to interface with the Sinclair ZX81 computer. I’ve installed Tubbutec’s excellent uniPulse MIDI retrofit in this, using the existing sync socket for the MIDI input. The drum voices are very responsive to playing dynamics, which I was pleased to find works great with the uniPulse’s velocity-sensitive outputs.
The sequencer board in this one was wrecked by a battery leak, which is sadly very common in these. The leakage also got onto the main analogue board, although fortunately not as badly. It ate up three of the potentiometers for the Tom 4 voice, and I haven't yet located suitable replacements, hence those controls being missing and blanked off; but everything else is now working as it should, having cleaned up corroded board traces and replaced a number of damaged components."
"A quick demo of the upgraded Le Strum MIDI controller. Available from six4pix.com/grandstrum"
"LE GRAND STRUM is a new version of our popular LE STRUM controller. It comes pre-assembled, in a larger format, with high quality 12mm tactile switches and gold plated strum pads.
To play MIDI notes, you hold down one of the chord buttons and touch the tip of the stylus to the strum plate. The contacts on the strum plate are mapped to notes of the chord across multiple octaves and you can create guitar-like strums, massive chord sweeps and arpeggios by moving the stylus across the strum plate.
36 chord buttons give you immediate access to 84 different chords (maj, min, dom7, maj7, min7, aug, dim for 12 root notes). You can also play sus4, add6 and add9 chord variations (with some limitations) The 16 pad, gold plated strum plate has a tapering layout which allows fast chord strums at the top and individual note picking at the bottom. Two new circular strum areas duplicate notes from the main pads and allow you to play continuous arpeggios by moving the stylus in a circular motion. Multiple chord modes are offered, including stacked triads, guitar chord voicing, “drone” chords on second MIDI channel and scale mapping for playing melodies 5 pin MIDI socket for direct connection MIDI synthesizer hardware or to a computer (Using a suitable MIDI interface/USB-MIDI cable) Long life from a 9V PP3 battery (7mA current draw typical).

"LOS ANGELES, CA, USA: Null Modular is proud to announce the official release of its n-1 Eurorack modular case — constructed from euro plywood with a clever flat-packable design that interlocks and slides together easily and needs no tools for assembly, instead including dowel pins for securing the wooden frame, pre-threaded aluminum rails, M5 hex socket screws, and M3 rail slide nuts — with pre-ordering open as of April 3…
As an unpowered case, n-1 offers users the freedom to select a panel-mounted power supply, or to adapt an internal power option; with 92mm/35⁄8” of depth, the case offers flexibility for a range of power solutions. It is available in two sizes — 48HP x 3U and 84HP x 3U — as the perfect partner for all stages of any user’s creative journeying into modular synthesis. Subsequently, Null Modular will release a range of accessories designed to enhance the n-1 case’s versatility and customization options, ensuring it remains an adaptable companion. But by using sustainable materials and efficient flat-pack distribution, n-1 is already one of the most accessible Eurorack modular cases on the market.
Masterminded in response to a friend’s request for ‘a simple box’ to house their Eurorack modules, prototype versions of the n-1 case have since become a cult favorite among musicians and designers from Los Angeles to France. Founded upon a design sensibility that is minimal, playful, and familiar yet peculiar, Null Modular creates products that resonate with users like a trusted friend. By balancing functionality with ‘feature wish lists’, the company continues to innovate in the world of modular synthesis.
Since Null Modular designs, prototypes, and manufactures all products in Los Angeles and Costa Mesa, California, it can efficiently experiment with materials and fabrication methods to refine its offerings. “Our modular synth community appreciates the tiniest of details; we take that to heart when designing and fabricating our cases,” comments Null Modular Founder Meghan Hui.
Having said that, then, modern music enthusiasts can join the Null Modular community in redefining the future of Eurorack modular cases by experiencing n-1’s clever flat-packable design for themselves!
What is in the box? 12mm plywood frame, 3mm plywood back Four dowel pins One pair of pre-threaded aluminum rails M5 hex socket screws M3 rail slide nuts Mystery stickers!
Expected to ship in May 2023, n-1 is available to pre-order at an MSRP (Manufacturer’s Suggested Retail Price) of $98.00 USD for the 48HP x 3U-sized version and $129.00 USD for the 84HP x 3U-sized version via San Clemente, CA, USA-based distributor Electro-Distro’s growing global network of dealers (https://www.electro-distro.com/dealers) or directly via the Null Modular website (https://www.nullmodular.com), which includes more information.

"Here is one of the first bass synthesizer ever made, dating from the 60s. Almost identical to the more widely know Basset, the Bass 1 is a basic but very effective little bass synth. You get a choice between a Sine and Sawtooth sound and a simple variable decay enveloppe ("Perc").
Synth was serviced: all electrolytic capacitors were replaced and a more convenient jack socket was fitted.
It is in perfectly working condition. Runs either on 220/240v or 110/130v."
