Torso Live Session #2: Mike Sheridan
video upload by torso electronics
"Torso Electronics presents the second live session recorded at our office space in Copenhagen.
This episode features Mike Sheridan, unfolding a 14-minute meditative dronescape of slow, evolving resonance. Subtle layers of frequency drift and intertwine, forming a weightless sonic field that invites for deep attentive listening. Performed on the Pin Portabella MK IIIe, the Z.Vex Instant Lo-Fi Junky Vexter, the Boss GE-10, and the S4 Sculpting Sampler.
About Mike Sheridan
Mike Sheridan has been a part of the Copenhagen electronic music scene since the mid 00’s. He entered the scene, barely in his teens, with his landmark debut album I Syv Sind (In Two Minds, 2008). Sheridan traced an ambient and dreamy approach, and with limited tools at hand, he constructed a teenage masterwork that few could have predicted. Among the first in his generation, Mike Sheridan launched his career to high acclaim, effectively crossing over to mainstream audiences.

The Florian Schneider Collection to Be Auctioned at JULIEN*S November 19
Note: links to listings are affiliate links for which the site may be compensated.
via JULIEN*S
"THE FLORIAN SCHNEIDER COLLECTION
Auction to be held at Musician's Hall of Fame & Museum, Nashville, on November 19
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
Category: Kraftwerk, Equipment
Provenance: PROVENANCE From the Estate of Florian Schneider

New Eurorack Modules Coming From Doepfer
Doepfer will be showcasing the above new modules at SUPERBOOTH25. Details on each follow.
Check with dealers on the right for upcoming availability.
Module A-119-2 is kind of a dual version of module A-119 without envelope follower. Instead two amplifiers are available and the module width is 4 HP only.
The module contains two amplifiers with separately adjustable amplification levels. Each channel is equipped with an overload display. The module can be used also for stereo signals, e.g. the stereo output of a smartphone.
Controls and displays:
Level 1/2: manual control of the amplification in the range 0 - about 45.
Overload 1/2: overload LED, begins to light up for output levels beyond about 10Vpp (+/-5V)
In 1: audio input 1 (monophonic or stereophonic, see technical details)
In 2: audio input 2 (monophonic)
Out 1/2: audio output (monophonic)
Technical details:
for higher amplifications the two amplifiers can be daisy-chained
normalling options: the signal applied to socket In 1 can be normalled to socket In 2 in different ways by means of a jumper on the pc board:
socket In 1 is connected via a mono patch cable (standard patch cable) to a monophonic signal and this signal is normalled to socket In 2 (i.e. the same input signal for both sub-units): jumper on pin header JP2 in upper position
socket In 1 is connected via a 3.5 mm stereo TRS cable to a stereophonic signal and the second channel of the stereo signal is normalled to socket In 2: jumper on pin header JP2 in lower position
no normalling: jumper is removed from pin header JP2
all inputs and outputs are DC coupled. Thus the module can be used also for the amplifications of control voltages.

Anvil UNIQUE 80sPercussion Synth NW
via this VEMIA listing
Click the auction link on top when you get there for additional listings.
VEMIA is Peter Forrest's auction house. He is the author of The A-Z of Analogue Synthesizer Books.
Pics of the inside below.
"The rarest drum machine in the world – the Anvil Percussion Synthesiser prototype. As featured in a major (four-page!) Electronics & Music Maker article in the magazine’s June 1985 edition. The Anvil prototype drum machine was intended to offer user-sampling and programmable rhythm sequencing as well as a drum synthesizer section that could be triggered by pads. However the project was perhaps too ambitious and the development money ran out in mid-October 1985 before it could be completed, leaving the Anvil residing in its flight-case in a London basement for 33 years before being tracked down. The Anvil prototype is not currently functional. A final update provided by engineer Roy Gwinn indicated the top board (control panel etc.) had been operational for a year (to October 1985) and was reasonably reliable. The bottom board (sample/synth) software had been able to sample into memory, replay from memory and save/load to floppy disk. The synth section was seemingly nowhere near completion, and some software had not yet been written. This was late-1985, and the Anvil has probably not worked since then. The Anvil has been powered up recently but the 40-character display was non-functioning. The 3.5 inch disk drive appears to be non-functioning. There are various builds of software/firmware on 12 EPROMs, some of which are populated on the two boards (PR for top board, BB for bottom board), along with two BIOS EPROMs. One early build EPROM (BB) has had a pin repair, and the other has a missing pin altogether. Some EPROMs have been confirmed as having data on them, and two have been copied in a limited (unsuccessful) attempt to get some life out of the Anvil’s top board. The internal battery has recently been removed from the unit. The auction includes the Anvil, the now-external/separate XLR-XLR input 240V mains power supply (with original UK plug), original Bulldog flight-case, the EPROMs, the schematics it came with (which in some cases differ from the current internal layout), a faded computer printout of the menu commands and final summary of work outstanding (16/OCT/85), and a unique (copy 1 of 1) professionally printed Preliminary User Manual written by the current owner collating all the paperwork, user guide, scans of schematics and his own personal full-colour photographs. CAUTION: PROTOTYPE – Should only be powered up by a suitably qualified electrical technician under close monitoring. The Anvil will require significant work to be restored. Weight: 22.3kg in flight-case. Dimensions 68cm wide by 43cm deep by 21cm high (in flight-case)."

Machina Bristronica 2024
video uploads by sonicstate
Playlist:
1. Bristronica 24: MyVolts The Silent Alchemist Nears Shipping
We caught up with Caroline who gave us the latest update to the *Silent Alchemist*, a versatile power hub designed for musicians. Featuring five isolated USB-C outputs and a high-wattage sixth output capable of delivering 100 watts, the device can power a Mac with the remaining outputs providing 20 watts each. Its independent circuits ensure noise-free operation, catering to a variety of devices including the Dreadbox module and Sysmo slope generator.2. Bristronica 24: Circuit Happy ML2M Clock Sync module updates
The Silent Alchemist uses innovative step-up power tips to convert USB-C input to the correct voltage for various devices. There's also new feature: an uninterruptible power supply allowing seamless transition between wall and power bank sources. Also introduced were updated cables, such as silver candy cords and floating ring TRS to TS cables, expanding connection flexibility. The Silent Alchemist is expected to be available in December with a competitive pricing strategy.
More Info:
https://myvolts.com/
At Bristronica 2024, we caught up with the creator of the *ML2M*, who introduced us to the latest version. The ML2M is a compact Eurorack module with Wi-Fi capabilities, allowing seamless synchronization with Ableton Live, Bitwig Studio, and iOS music apps using Ableton Link without the need for cables. It either connects to an existing network or creates its own, ensuring robust sync even in environments with unreliable Wi-Fi. The module, which retains its 2HP size, now features MIDI integration through TRS jacks. Users can access a web interface to configure each output for different clock divisions and reset triggers, making setup straightforward and flexible.3. Bristronica 24: Archaea Exchange Patching Module
Alongside the ML2M, there's also the Missing Link Junior. This desktop version offers the same functionality but in a box format, complete with MIDI and CV clock outputs. Both products are now accessible, with a starting price of $250.
At Machina Bristronica 2024, we caught up with Arran from @archaea_modular_synthesis who presented the *Exchange Module*. This programmable patcher, a year in the making, evolved from its early prototype stage to a fully functional module. Arran explained how the Exchange can route synth voices via a beam controller and three exchange modules installed within the skiff, allowing for versatile patching. Operating like a matrix patchbay, it enables users to select inputs and outputs with the push of a button, create presets, and chain multiple modules for synchronized patching.
Communication between the modules occurs over the Eurorack power bus as well as over MIDI via the USB-C connection. The Exchange maintains analog integrity, ensuring there’s no conversion latency. The forthcoming release expected in late November 2024, includes a USB-driven editor for enhanced control capabilities.

20 pole Phaser by Jurgen Haible running 808 track
video upload by VanDaalElectronics
"This is a project built on Jurgen Haible 20 pole phaser board. Cases are custom made by us @Van Daal Electronics.
Assembled units can be purchased from: https://vandaal-electronics.com/
For DIY builds PCBs can be ordered from https://serge-modular.com/haible/tau_..."
Additional details:
Jürgen Haible's legendary redesign of the Tau 'The Pipe' Flanger - actually, a Phaser, using 20 (twenty!) all pass filter stages is back in a slightly modernized version, including some additions and modifications compared to the original Haible board:
Transistor arrays (for the 20 poles): pcb supports super-matched THAT300 (DIP) or BCM847DS (SMT).
Obsolete CA3046 in the 1/x function generator has been replaced by LM3046 (SMT).
MTA-156 power connector for +/-15V added - don't install the onboard-PSU parts if you use +/-15V!!!
MTA-156 power connector can also be used for 10 pin Euro power connectors - please note that +/-12V is experimental, not supported (yet), see below!
LFO: slow mode option has been added (simply connect L* to UP2 or DOWN1 via SPDT switch).
Optional CV mixer/processor has been added (untested!).
Connectors have been moved to the edge of the board to allow connecting component pcbs via pin headers - downside: space may be too tight to use normal headers. Workaround: use (breakable) precision sockets for manual wiring or testing.
pcb size: 6" x 3.4"

Roland G-505 Guitar Synthesizer Controller, GR-300 Polyphonic Guitar Synth
Note: links to listings are affiliate links for which the site may be compensated.
via this listing
"Up for sale, a 1980s Roland G-505 Guitar Synthesizer Controller and GR-300 Polyphonic Guitar Synthesizer [SN 090427] in 100% original condition and in perfect working order,
complete with the original 24-pin cable. First introduced in 1980 as a follow-up to the GR-500, the GR-300 is perhaps best known for its usage by Pat Metheny; produced at the venerable Fujigen factory in Japan, this versatile guitar synth can deliver a huge range of decidedly unique sounds, with a hexaphonic fuzz circuit, VCO synth, and combinations of the two. This GR-300 comes complete with the G-505 Guitar Controller, taking its design cues from a Strat with a sleek ash body, one-piece maple neck, and a trio of single coil pickups alongside the synth pickup.
The G-505 Guitar Controller guitar has plenty of natural sparkle and shimmer, and the Roland PU-134S pickups deliver a bevy of Strat-style tonalities via the five-way selector switch. Weighing 8lbs 12oz, the G-505 has been professionally setup here at Mike & Mike’s Guitar Bar with 10-46 strings, low action, and spot-on intonation.
The maple neck has a slender C-shaped profile carve with good shoulders, gaining appreciably more heft and roundness in the upper registers, measuring .810” deep at the 1st fret and 1.015” at the 12th. The fretboard exhibits light finger wear through the gloss, and the slender fretwire ostensibly benefits from a level and crown in this guitar’s lifetime, showing virtually no wear. This Roland plays cleanly up the 25 1/2“ scale with a straight neck and a responsive, optimally-adjusted truss rod, and the nut measures 1.650” (42mm) in width. The headstock features a bullet truss rod nut and gold “GR” logo, and the Gotoh tuning machines function reliably. The back of the headstock retains the silver foil serialized sticker.
The electronics on the guitar controller are untouched, with a control scheme including Master Volume, Guitar Tone, Guitar/EG Balance (Blend), VCF Cutoff Frequency, VCR Resonance, and LFO (Vibrato) Depth knobs. Additionally, the three-position Mode toggle enables on-the-fly switches between Hexaphonic Fuzz only (Mode 1), Fuzz and VCO synth tandem (Mode 2) and Synth only (mode 3). The controls are capped by the original sextet of knobs with ridged grips for easy adjustments, and the three-ply white pickguard rounds out the plastics.
Cosmetic wear on the gloss Metallic Blue finish includes a number of nicks and dings on the body as a whole, most prominent along the lower bout perimeter, with some finish chipping adjacent to the output jacks, and some very subtle texturing in the finish on the top. The neck profile retains its smooth gloss, with a handful of shallow marks that have no impact on playability.

Roland GS-500 Synthesizer Guitar *AND* GR-500 Synth Module SN 661034
Note: links to listings are affiliate links for which the site may be compensated.
via this auction
"This joint venture instrument between Roland and Ibanez is paired with the Roland GR-500 module. It was used by a multitude of artists, ranging from Neal Schon of Journey to Jeff Baxter of the Doobie Brothers and was responsible for creating some of the wildest synth guitar sounds of the late 70s and 80s.
The guitar features a hexaphonic pickup that tracks the pitch of each individual string with high accuracy, as well as a traditional humbucker pickup for producing standard guitar tones. The signal is sent through the guitar’s 24 pin output to the synth module where it can be manipulated using a multitude of VCOs VCAs filters, and effects. One of the most unique elements of the guitar is the infinite sustainer system built into the guitar. Similar to how E-bow’s work, this instrument can keep the strings vibrating as long as the player wishes.
This guitar is in excellent condition. It has only a handful of small chips/dents on the top (pictured) and the fretwear is nonexistent. Its electronics have been cleaned, the fretboard conditioned, and setup to play well at low action. The GR-500 Module has been well cared for, and is in excellent shape. Bring your guitar music to the next level with the GS and GR 500s today!

This guitar is in excellent condition. It has only a handful of small chips/dents on the top (pictured) and the fretwear is nonexistent. Its electronics have been cleaned, the fretboard conditioned, and setup to play well at low action. The GR-500 Module has been well cared for, and is in excellent shape. Bring your guitar music to the next level with the GS and GR 500s today!

Roland GR-500 Guitar Synthesizer with GS-500 Guitar and 24 pin cable
Note: links to listings are affiliate links for which the site may be compensated.
via this auction
Two pics of the of the GR-500 inside below.
""Listed here is the flagship of the legendary pre-MIDI, all analog guitar synthesizer systems; The Roland GR-500 synth and GS-500 guitar.
This listing includes the Roland GS-500 guitar controller, The Roland GR-500 Synth module and a factory 24pin cable.
The GS-500 guitar is in Very Good condiction with all of it's original electronics, including the hexaphonic pickup, synth controls and 24pin connection to the GR-500 synth module. The gutiar hasn't been modified at all (as far as I can tell). The original pickups are intact as are the string isolators which are essential for the mulichannel infinate sustain system to fucntion. There are a few -very- small scrapes and dents as one might expect from a guitar from 1978... but overall it looks like this insturment wasn't used heavily and it looks great.
The GR-500 synth itself has recently been serviced (2023). It just got entirely re-capped (capacitors replaced)s, power supploy serviced, and several of the chips were changed from soldered to socketed.
Almost all of the features of the synth work well. The Guitar, PolyEnseamble and Bass sections work exactly as you'd expect them to. The PolyEnsemble and Bass sections are remarkably cool. Being able to play fully polyphonic chords on an anlog guitar synth is just a beautiful thing.
The Solo Melody section, however, is currently not functioning quite correctly. Right now the pitch of the Solo Melody section does not track the pitch of the guitar correctly, and the amplitude detection in this section doesn't seem to be tracking correclty either. I am not sure what the issue is, but two techs have suggested that this section may just need to be properly calibrated and the instructions for this procedure can be found in the service manual which is readily available. I regret not having the time in my life right now to address this issue as it may be quite minor, but I just can't say what this issue is for sure and I wanted to be totally up front that this issue exists.
So we have this remarkably, unique and rare set of GR-500 and GS-500 where the gutiar is in really nice shape, and the syth has recently been serviced and cleaned, but does have some issues with the Solo Melody section."

The Cloney Project EMS VCS3 Clone w/ Mods + Custom MIDI Box
Note: links to listings are affiliate links for which the site may be compensated.
via this auction
"For your consideration is this 100% faithfull VCS3 recreation that has been professionally built by RAMCUR who built The Hornet Modular with PIN Electronics from a few years ago. I also recently got it fully modded by Z3 Sound with a custom MIDI input box.
The main parts of this synth are from a kit from Germany's The Cloney Project. As you can see in the pictures, we upgraded a number of parts (solid shaft CTS pots all around being a significant upgrade to the feel and longevity) with premium parts as well as a number of period correct electronic parts where needed in the audio path. We also used the same spring reverb tank, meter and joystick pots that EMS used in their original design. Furthermore, the matrix is a custom Swiss made 16x16 Ghielmetti which is far superior than the the one that came with the kit. In fact, Ghielmetti make the best patch matrixes in the world. This synth sounds and feels amazing, it was built with no expenses spared.
Aside from the main build, here are the mods that were added:
1. Hi/lo Range Switchable on all OSC (3x switches, 2-pos)
2. OSC Variable Sync via pot on all (3x 10KL pots)
3. Voltage Controlled Shape on all OSC via patch points (3x jacks)
4. Voltage Controlled Filter Response (1x jack)
4. Filter slew / unslew (1x switch, 2-pos)
5. Filter 24db / 30db (1x switch, 2-pos)
6. Attack / Decay x10 (1x switch, 2-pos)
7. Trapezoid polarity switch (1x switch, 2-pos)
8. Variable Portamento (2x jacks + 10KL pot)
9. Custom MIDI / Eurorack Input Box (via Cinch Jones)
10. Sustained / Transient External Gate (via MIDI box)
11. Variable Portamento (via MIDI box)"
