In our studio we have over two dozen high end synths like the Moog Voyager, Prophet 12, Oberheim BXA, etc. The his is one of the favorites we have, especially for drums. we are slimming down to about 6 though and selling off quite a bit right now. Super rare and highly desired after by those in the know. Includes the 140 page manual too!

The ultimate analog Italian synth for the ultimate synth collector. Up there with Moog, Dave Smith and Oberheim (even reminds me of the Oberheim expander module). This has quickly become my new go to for songwriting and scoring and you’ll read why.

An incredible monster of a machine and paired with its powerful flagship expander module, as rare as hens teeth. Comes with unobtanium English translated manual and separate 250 page TS4K Italian manual (translated by a fellow enthusiast!).

I actually have very little interest in selling this to be totally honest, I’m just so proud to even own and use it in the studio every day. Both have been fully refurbished and serviced to get them in pristine operation which is described as flawless.


rare and extremely cool. Mind blowing quality from otherwise obscure manufacturer. Known as the Italian Disco box, this analog synth has 10x the features of other synths of this era.

We’ve all seen some amazing stuff come out of Italy, such as Vox and Binson, and the Solton brand by Ketron labs is some of the coolest analog synths ever made and certainly garners my vote for best Italian synth of all time. 

Both items listed in this sale are flagship, top of the line products from Solton too. The TS4K is the big brother of the Solton Programmer 24 and features everything from an onboard sequencer to AMAZING analog drums, to synth to strings… everything you’d want out of a modern analog synth and more. Perfect for studio or performances. 

If you are unfamiliar with these incredible synthesizers, get ready to o be shocked at what you’ve stumbled across.

We start with many familiar sounds and presents you’d expect from a great synth: Lots of great synth leads, orchestral and band instruments, great strings, etc but what REALLY sets these two machines apart, for me personally, are the incredible drums. Im an analog drum junkie and have collected pretty much every iconic machine known to man, this machine astounds me. As thick and wide as anything else out there, and one the very best at this price. Bold statement I know but true. I believe that if Michael Jackson and Prince had heard the TS4K drums, especially the integral kick & snare, they would’ve completely lost their mind like I did when I first heard them.

These drums have been on everything I’ve made since I got them and have the thickest, beefiest hip hop swag you can imagine. They sound killer on all pop genres and have 7 separate physical outputs for each drum like the Oberheim DX or the Linn drums!

The coolest part is each of the 7 drums, which you can sequence, have their own separate 1/4" output for studio tracking and mixing! 

Another thing you'll love about these two keyboards is the built-in widening chorus on all the instruments aka Roland Juno. If you have ever used a Juno-106, you know how powerful the chorus section is, and arguably what put the Juno on the map in the first place. Sultan took an obvious cue from Roland and added that exact MN3009 type BBD chip to these keyboards to make them wider and fatter than any other keyboard of its day. It gives these keyboards the same larger than life, 3D holographic sound that cemented the Juno/Jupiter line of keyboards as some of the best sounding analog synths of all time. These have that same sound I adore.

The last thing I really like on these synthesizers is the ability to sequence onboard. You can build out a song in the Sequencer and save it to floppy disk or internal memory and trigger different sections with the included foot controller for live performances. It’s extremely unique and way ahead of its time. It also has tons of groovy presets you can alter and add sections to. It’s quite versatile indeed and lends itself to any genre you throw at it beautifully.


Included in this listing is the TS4K flagship keyboard and their flagship MS40 multimedia music station. The MS4 was the little brother of the MS 40. The MS 40 is the flagship expander just like the TS4K was the flagship keyboard. Both are the best Solton had to offer at the time, to my knowledge.

Please note that the MS40 is American standard 120V but the TS4K is 220v. I am currently using it with a large step down transformer but you will need to grab one on eBay for 20 bucks if you don’t already have one (every studio should have a few anyway imo) or I can sell you mine for $20 if need be.

This listing also comes with a powerful switching PSU box for the TS4K with proprietary cables, as shown. Also included is the foot pedal expander which operates on a SCSI connector which works for either unit (both units have a foot controller SCSI input). Everything is in great shape with no issues at all.
