High and mighty- The ARP 2500 w/Don Slepian @ RetroLinear


"Resurrected from the dead, the mighty ARP2500. A rather lengthy restoration project requiring nearly countless hours of reworking, development of new circuits, reverse engineering failed potted modules to restore operation and improve performance.

Don Slepian paid us a visit and kindly recorded around 20 minutes of musical snippets on the ARP2500 which has been arranged as a single track for your enjoyment!

Many thanks to Don for his musical expertise in steering the ARP2500 and Edwin Kiddo for his 2500!"

Pittsburgh Modular's Black Corporation Kijimi SN 1604

Or is it SN 1603? See the pics below.

Note the seller for this one is Pittsburgh Modular so likely safe. :)

"Black Corporation Kijimi was purchased new by Pittsburgh Modular Synthesizers for use in our studio. We used this unit on our studio for a few months before it was packed up.

** There is a scratch on the top of the case. It is highlighted in one of the photos.

** "Kijimi" is written on the power adapter in silver sharpie so I would not confuse it with other power adapters. This is visible in one of the photos.

The sale includes everything that we received with the unit. Original box, power adapter, and documentation. The synthesizer will be double boxed and shipped from Pittsburgh Modular Synthesizers.

Keith Emerson Signature Voice Crystal 3 D-50 - 64 Voice RAM Card for the Roland D50

via this auction

"64 voice sound bank storage card. Works great but you could probably change the battery. Plastic case is in worn condition but has protected the actual card well"

Curious if these had Keith Emerson patches for the D-50 or if they where just some promotional branding deal. The discription does not say.

TONSTURM Windmaschine

"Introducing WINDMASCHINE - The 'Windmaschine' is a virtual instrument based on the recordings of the very rare Mole- Richardson Windhowler Moleeffect Type 2281.
but of course it goes much further.."

TONSTURM Windmaschine Tutorial Videos


"With Windmaschine we are proud to present a playable VSTI that is a faithful reproduction of the Windhowler Mole Effect but also takes it to a whole new level.

The Windhowler is an electrical instrument developed in the 1960s which can produce unique wind sound effects with a very special sound signature. Only a few devices exist and the one the entire planet and luckily we had access to a unit in mint condition. We captured every single detail in order to preserve its sound signature and character.
In combination with our visionary software engine these captured recordings are transformed into a virtual instrument that allows you to go to sonic territories way beyond what the original device is capable of.
Meticulously capturing the original
We invented a way to meticulously capture every possible setting of the original Windhowler hardware. We attached a script controlled stepper motor to the wind speed dial. Each resonator sample set finally consists of 120 short loops that are cross blended in real time when performing WINDMASCHINE.

Perform dynamic wind effects
As on the original hardware everything starts with the resonators.
You can load one of the 19 available resonator sets into each of the four source channels.
The whole sound engine comes to live when performed by our powerful wind modulation system.

Custom Wind FX
The FX section of WINDMASCHINE allows you to tune its sound character to the mood you need. Or to change it drastically.
Tailored Effects invite you to explore different sides of wind.

True Stereo Convolution
Finally everything is set into stage with our beautiful sounding convolution reverb engine.
It comes with custom recorded true stereo impulse responses providing a breath taking sound quality.
Besides nature, exterior and indoor impulse responses we included IR recordings from musical instruments like gongs, sound bowls or cymbals enabling WINDMASCHINE to create lively textures, drones and atmospheres.

Price: $129 introductory price until 27 / Oct / 2020 ($179 thereafter)"

Bruce Lee Spice - A Supercritical Neutron Flux piece

Supercritical Synthesizers

"'Bruce Lee Spice'

Couple times a year, we make this awesome chili sauce with Timo. I call it Lee spice. Or Lie spice of the Lie algebra of the Lie group, as Timo calls it. Ask him why. It has really hot and fine chili powder, some szechuan pepper and sesame seeds. First you heat some oil as hot as it gets (without setting everything on fire) and then roasting the dry ingredients with it. Pour and mix. Never gonna eat tacos without it.

This bassline is an ode to that spice. The Neutron Flux is set on Fat mode which is our take on the transistor ladder’s characteristic. The Model D is of course the best one there is for this use but we added a couple of interesting features.

The basic four pole mode has some traditional crunch and resonance but the one and three pole modes have some handy features. Left channel has a normal resonance (without bass compensation) but the right doesn’t. Halfway through, I’ve split a mono signal into both cores (normalled from the left jack) and then summed them back into mono. That’s the Thriller trick. Michael, Greg, Quincy and Bruce needed two Minimoogs in parallel to do that.

The clip features also the eight pole mode. That means two four pole ladders in series. A kick in the guts like Bruce Lee.

Oh yeah, go listen to KNOWER and Louis Cole. The weather report says that their funk is searing hot.

Étude No.5 - Freak/Muxlicer/ReduXer/Mimeophon/Arbhar/2HP Freez/Rampage/BIA/Desmodus Versio

Omri Cohen

You can find additional resources available from Omri Cohen at

"Here are some patch notes:
- I have Freak set with the Vraids firmware which gives me a dual Braids, and I have it set to PLUCK mode.
- It's being sequenced by Muxlicer, and the gate mode of Muxlicer is being modulated by S&H from the Intellijel 1U Noise Tools.
- This Freak is going to another Freak set with a band pass filter, and its cutoff is also being sequenced by Muxlicer.
- From there the signal is going to ReduXer from VoicAS, and its amount is being modulated by Muxlicer as well.
- This is going to the Mimeophon and the Flip, Zone, Color, and Halo are being modulated by S&H.
- From there one output is going to Arbhar and the other to the 2HP Freez.
- Arbhar is set to continuously record the input, and I'm modulating its reverb amount with S&H.
- I'm triggering the 2HP Freez with the Rising output of Rampage, and I'm modulating its size with the Max output of Rampage.
- The Keystep Pro is sequencing the Basimilus, which is going to the Desmodus Versio, and I'm modulating the Size and Dense with the Min and out A of Rampage."

Nord Modular Rack

"Nord Modular Rack (1st Generation) made by Clavia. This model is fully functional; all pots, switches, jacks, and displays tested in working order. It has a UK plug (230v version), and the latest firmware installed (v3.03).

This unit has only ever seen light use in a home studio, as you can see by the condition. It’s not quite mint - there’s a scratch pictured to the left of the Master Volume label.

It’s worth knowing that Byte Order have recently released a new G1 editor, compatible with OSX 10.11, Audio-Unit, and VST3 plug-ins."

Yamaha CS-50 4-voice Synthesizer

via this auction

"This particular 4-voice synthesizer is in excellent condition. If allowed ten minutes to warm up, tuning and scaling are stable. Many great features eg glissando & the famous square-wave modulation (Simply having a wonderful Xmas time). Some of the 13 presets are forgettable, but entering panel mode, all is forgiven....its great fun! Its a true piece of analogue history; exceptionally well constructed...and everything works!"

"Arpoloop controlling Arpopone little brother and cat scream !!!"



"I just received my multitrack tape recorder, and I so pumped up. I've never used one, I've watched some demo and many, MANY videos on YouTube (and Instagram, where it seems to be mandatory). I will keep it simple: it sounds amazing. I am the farthest thing from an audio expert, but there is something really pleasing in the way the otherwise normal drums sound: they're at the same time crispy and soft, tight but rubbery. Loving that.

And, with the recording part taken care of, I could improvise a little bit with my guitar, and BAM, magic happened, and in just a few takes I was very satisfied with the result like I am almost never been since!

So guys, do yourselves a favor and buy a multitrack tape recorder (they are cheap), a guitar (they are also VERY cheap, nothing compared to a synthesizer), and maybe a Synthstrom Deluge too (they are not cheap, but they are sort of priceless for a quick idea laydown)."
