"Not the Colossus but also not for ants. This semi-modular analog Synth is patched with 6,3mm (1/4') cables like his Moog or 4U cousins. Unlike them it can also be played via MIDI. The Red Square can also process external signals with an input at the front as well as two inputs on the back, hence the 'patchable analogue effects processor' moniker."

"Analog Solutions Red Square synth, No issues at all, everything works as should. Just came back from a full inspection and calibration from professional audio tech.
The red square is a patchable analogue monosynth that can also be used as an effects processor. it has some of the advantages of a modular synth (re-wireable synth circuits, external control, external signal routing) and the advantage of a pre-patched monosynth (easy to use, instant sound, tidy front panel). its 1/4" jacks sockets mean it can easily be integrated into a studio just like any synth or processor."

Analogue Solutions Ample Desktop Monophonic Synthesizer
Note: links to listings are affiliate links for which the site may be compensated.
via this Reverb listing
"Mint condition...... And heck if a lot of fun and sounds awesome.
comes with all accessories (matrix pins/cables/power)
In perfect condition, everything works like it should. 2 to3 day shipping...
Ample combines the best elements of several of our recent products.
The sound elements of Fusebox
Jack patch points of Concussor Eurorack
Patch pin matrix of Vostok
Echo from Dr Strangelove
Sequencer and CV touch pads of Generator
It shares all this yet still has its own sound!"
Ample can be as complex or as simple as you want it to be
We have given this synth a large and diverse number of controls, that along side the patch sockets, will give even the best and experienced synthesist endless possibilities.
We have presented the controls in a user friendly and familiar synth layout that, together with this manual and other resources, enable even the new guy to get great sounds.
SYNTH – PERCUSSION – AUDIO PROCESSOR
Ample is a compact analogue synthesizer. Analogue - as in really analogue. Aside from the MIDI chip (which has to be digital), everything else is totally analogue using real transistors and op-amps. There are no CPU stabilised and quantised circuits, no DCOs, no digital LFOs and no digital EGs, as found on other so called analogue synths. The circuitry is based on designs dating back to the mid-1970s. So Ample has a genuine old sound.

"Here’s a fun little impromptu jam driven by the 64-step AS500 SEQ.
The AS500 SEQ is the master clock for the entire setup and controls the Odyssey’s lead line using CV pitch and gate.
Maximus follows the AS500 clock, and different parts fade in and out using its built-in stereo mixer sliders.
Recorded directly with no effects."

Analogue Solutions Maximus 8-Voice Polysynth
Note: links to listings are affiliate links for which the site may be compensated.
via this Reverb listing
"This is the big boy 8-voice Maximus. It's in superb condition and includes everything it would if you purchased it new. Analogue Solutions makes the most 70's sounding synths in the modern era IMO. Raw, present, fat, but with all the modern accoutrement (modern MIDI, connectivity, etc). I have owned all the legendary vintage big boy polys at some point or another and the Maximus is on another level. Most would agree the 8-voice Oberheim is (EVS) is one of the greatest vintage polys of all time. The Maximus is essentially the modern equivalent but with a dedicated sequencer per voice, more global controls, built in delay per voice, and a superior mixer section. This is unit 15, but serial #22 by special request. I suspect no one will ever build an analog synth like this again as it's a labor of love and costly.
I recommend local pick-up here in Vegas, but I have the original crate it shipped in from England. These rarely come up for sale, especially Stateside, and now with tariffs the way they are you're gonna get hammered buying a high ticket import like this. If you were considering a Maximus, here's your chance.
Hand assembled by Tom in the UK."

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

Analogue Solutions Semblance: 4 Voice
via this Reverb listing
Additional NOISEBUG Listings
"SUPER RARE!
Pristine condition - Fully functional, Comes assembled to a 13U rack.
Semblance / 4Voice is a self contained TRUE analogue synthesiser. The voice circuitry is entirely analogue, using all discrete and op-amp components. There is no voice DSP happening! Semblance / 4Voice has a similar sound and specifi cation to the classic Oberheim SEM, but with many improvements such as MIDI, Noise, more modulation. Note however, Semblance is not intended to be and is not a clone of the SEM. If you want a true SEM sound, buy a SEM! The 4Voice version has a Poly mode, to allow four the voices to be used as one big 4-voice poly synth"

AS Vocoder Improvisation – Full Session
video upload by Analogue Solutions
"Here’s the full video session showing an improvised vocoding performance with the Analogue Solutions AS Vocoder. This unit is built into a Colossus Classic, though it’s also available as a standalone module.
Deep, low-pitched speech runs directly into the vocoder, while Oscillator 1 provides the carrier signal.
The AS Vocoder features 12 sets of 4 band-pass filters, with flexible CV routing, muting, and re-patching options. A true sound design powerhouse."

The Matrix is Breathing | Colossus Synthesizer #shorts
video upload by Analogue Solutions
"One of two colossal pin matrices on the Analogue Solutions Colossus synthesizer driving this hypnotic sequence into uncharted territory. Every connection is a new possibility, every route a step deeper into evolving soundscapes. The sheer scale invites exploration, and the tactile freedom makes it as much an instrument of performance as it is a work of art."
