"EMS Synthi AKS 1970s Synthesizer. This listing is for the A unit only. However, the KS (keyboard-sequencer) will be available separately and is currently being serviced by Rosen Sound.
This Synthi was purchased from the original owner who taught sound design with the unit. It is fully functional and sounds absolutely incredible. It is hands down an absolutely beautiful instrument. It is incredible for sound design and re-amping. I’ve used it as a recording tool for the past few years and it’s in studio-ready condition.
The original lid is in good condition and both original latches are fully functional. The original handle is in very good condition. Feel free to ask any questions."

Oberheim OB-8 w/ Moog Style Knobs & Fatar Keyboard
Note: Auction links are affiliate links for which the site may be compensated.
via this auction
"The GOOD!!!
- I just paid $2000 in service fees that include a recapped power supply, deep cleaning, Synthchaser Voice Board Service Kit with extra trimmers, new IC chips / IC sockets / Op Amps / Transistors / Film Capacitors, etc.
- I just bought and installed a brand new (and MUCH better) Fatar Keybed that plays and feels beautiful.
- I just bought (but have NOT installed) a brand new Midi Mod Kit, Battery Eliminator Chips (so you no longer need a battery to save patches!), and wood end pieces from Rosen Sound. These are brand new and in the boxes.
- In all I have put over $3000 into this classic 8 voice, 2 osc, 3 lfo, monster analog synth.
The BAD!
- This synth does NOT like to be cold. When it is cold it sometimes takes 15-20 minutes to warm up and stabilize. When first turned on a couple voices sound terrible and that usually causes some serious panic. After it warms up I just hit the auto tune and it's usually solid after that. The crappy video included shows the synth warmed up after it was cold from a near by AC blasting all night long. The sound is just coming out of a stereo speaker but you get the idea.
- The knobs appear to be Moog style knobs. I think they look great but if you want it all original you will have to track down Oberheim knobs. Personally I don't like the original knobs. I also have the original keybed listed for sale if you want to have that one too."

Moog Source SN 3696 w/ Encore MIDI
Note: Auction links are affiliate links for which the site may be compensated.
via this auction
"To me this sounds better than most late 70s minimoogs Ive used and you can save 256 patches on this! This Source is the one you want and will save you a TON of headache in the future. This source has been serviced in 2021 by the best in the business right now, Rosen Sound, and sounds absolutely fantastic. The fine folks at Rosen sound rebuilt the power supply to help future proof the rest of the components and increase stability. They also installed a new Encore Midi which adds midi sync ability, midi in and out, and expands the memory 16 times the original, these are 325 new plus installation. Please research the encore midi system before purchasing. They also replaced the two light sensors for the control knob with NOS parts and calibrated to factory specs. These all will go and these parts are getting harder to find, like damn near impossible, and very hard to install/calibrate. It took Rosen Sound months to source these parts alone and they probably own the last remaining available for these. This control knob is now ready for another 30 years of use and this synth is impossible to control without it. As it is the membrane works perfectly but it also comes with a spare membrane panel from which is supposed to be the best replace panel available for when the membrane experiences problems in the future (they all go bad eventually). Parts and labor for all of this future proofing on a once very finicky synth was about 1500 dollars. If you buy a different source and want to keep it alive I would expect to pay the same in the near future."

Studio Electronics MIDI Mini
Note: Auction links are affiliate links for which the site may be compensated.
video upload by Mineral Sound
"Here's a short demo of the Studio Electronics MIDI Mini/Minimoog Model D I have listed for sale on Reverb. Some playing around with bass/lead sounds, going through the oscillator waveforms, and sweeping the filter to show how it sounds and performs. Using a Juno-106 as a MIDI controller, not included in sale!"
via this auction
Pics of the inside below.
"this is one of the early versions with the original sound boards ripped out of a Minimoog Model D. Some might call it sacrilege, I call it a great way to get authentic, vintage tone in a 4U rack!
This unit is freshly returned from service at Rosen Sound in Burbank, CA. No oscillator drift, all pots, switches and functions in working order! But there's only so much I can describe in words; check out the demo video I made (above, after the pictures) to hear it in action. This thing is FAT. Floor-shaking basses, screaming leads, and saturated resonance; if you know you know, there's no substitute for the OG Moog sound.
The only functional issue I've found is that the VCO pots are a little scratchy, and the VCO 1 pot has a little trouble clicking into the rightmost waveform (PWM square). I spoke with the tech and since the pots are no longer manufactured, the only solution would be to machine new pots, which would likely cost more than the unit itself. But if that's the only issue for this 40-year-old beast I'd say it's doing pretty well!
Cosmetically the item is in great condition; the faceplate is more or less pristine, with only some very light rack wear on the mounting tabs. The top of the unit has some scratches and scuffs (see pictures),as it's a bit of a tight fit getting this into a rack (but of course those scuffs will be invisible once mounted). Back and sides are in perfect condition."

gettin moody with the 1981 Oberheim OB-Xa
video upload by J3PO
"The Oberheim OB-Xa is one of they vibiest synths of all time, in my opinion. This video is an exploration of tone and sound, hopefully capturing the essence of the beautiful pads, strings, plucks, and soundscapes that the instrument is capable of creating. Some patches are factory and some are presets I've made. The OB-Xa is also capable of making incredible basses, aggressive brasses, leads, and so on, but in this video, I've decided to present to you what I think the instrument excels at: the softer side of things--creating moody atmospheres and melancholic tones.
This particular OB-Xa was serviced recently by Rob Rosen at Rosen Sound in Burbank, CA.
I have preset banks available for the Prophet Rev 2, Prophet 6, OB-6, Prophet 5/10, XLN Audio's Addictive Keys Mark One, Softube’s Model 84, and the DiscoDSP OB-Xd available on my website www.j3po.net. If you're a Nord Stage 3 user, download my bank from the Nord Keyboards website."

Oberheim Two Voice TVS-1 Restoration
video upload by Rosen Sound
SN 0394
"Welcome to our new YouTube channel! We are excited to get back into making fun videos. In this video we give a peek into the various aspects of fully going through an Oberheim TVS-1, also known as the Oberheim 2 voice, a SEM based synthesizer from the mid 1970's
Join Rob and Eli's disembodied voice restoring one of our favorite synthesizers ever made!
For service, rental, and sales, please visit us at www.rosensound.com
This specific TVS was sold to us by a client who purchased it from our client Peter Freeman many many years ago. Peter recently passed away, and we dedicate this video and this TVS-1 to his memory. RIP!
This TVS-1 is not for sale, however can be rented among many other vintage synthesizers in our rental fleet.
Thank you to Benny Bock for providing the demo at the end for this video. A longer version will be uploaded soon.
Background music by Rob Rosen (though really, the TVS plays itself!)"
This one was spotted and sent in via Soviet Space Child.
SCI Pro One - Rosen Sound Demo
video upload by Rosen Sound
"Somehow this never got listed public. This demo is by Eli Goss and is shot in the a reverb chamber that was built for Captain & Tennille, which was then torn down to build what is now the synth cabin.
Not much to add to this considering I’m listing it public 2 years later, but its none the less an awesome demo by the venerable Eli Goss"

Memorymoog Sound Design
video by wedream2
"I finally got an opportunity to take a deep dive into sound design on the Memorymoog (after complete restoration and upgrades performed by Rosen Sound). I tweaked most of the factory sounds and added expression pedal programming to each. In the following examples, a factory sound is identified by the bracketed number and the name of the factory sound. I also created original sounds that are identified by name only (no bracketed numbers). I used the additional stereo outputs recently installed, so listening through stereo headphones is recommended. The panning positions of the voices cycle, similar to the OB-8, except when the cyclic memory mode is selected, where upon the same key repeatedly played, holds the same pan position. To avoid going over an hour in length, I eliminated multiple factory and original sounds from this demo. The more interesting and complicated original sounds are showcased."

Roland Jupiter-8 w/ MIDI
Note: Auction links are affiliate links for which the site may be compensated.
via this auction
"Rare 14-bit version, also referred to as the "JP-8A". It was serviced a few years ago by Rosen Sound, where they replaced the DCB port with a more practical MIDI option. The "LFO Waveform" knob is a bit wobbly, but works fine. If you are skilled with repairs, replacement pots can be found online for $20 bucks ;) Otherwise, this synth performs great, sounds incredible, and ready for your next recording project."
