S4: Track in 10 – Making a track using a sine wave
video upload by torso electronics
"An empty project and 10 minutes on the clock. In an uninterrupted one take we explore ideas, sculpt sounds, and let the S4 sculpting sampler guide the moment. "Track in 10" is about staying in the flow and creating without overthinking."

"This is an incredibly lush vintage analog powerhouse of a synth with three distinct sections (Synth, Brass, Strings) and an insane onboard flanger.
I bought this earlier this year from Rosen Sound, who had completely serviced it. Everything is working and sounding fantastic. Internally its in 'excellent' condition externally its 'very good'
As to be expected for its age it has some cosmetic signs of wear on the wood furniture and panel but in truth it looks excellent besides these small blemishes."

"If you know, you know. These almost never show up, and there’s next to no info online. It’s one of the hardest Hohner keyboards to track down.
This unit is in excellent condition, both technically and cosmetically. The real-wood casing is beautifully preserved with only light signs of use. Keys, switches, sliders—all exceptionally clean.
Everything functions perfectly.
All sound registers can be switched or blended freely
Built-in vibrato + sustain
Dedicated bass voice for the lowest octave (individually switchable)
Individual volume controls for each section
Key contacts are flawless—no dead notes or crackle
Accompaniment System:
The auto-accompaniment can run silently if you want only the bass sequencing. Changing rhythms reshapes the bass pattern, making for surprisingly interesting and musical sequences. The onboard memory hold lets you tap a bass key once and have it sustained automatically—works even without the rhythm section active.
Sound Output:
Built-in speaker underneath (clean, zero distortion)
Line-out on the rear for external amps
Pedal input (pedal not included)
Dimensions: approx. 82cm W × 19cm H × 40cm D
Weight: approx. 12.7kg
A seriously rare piece—clean, fully working, and ready for a new home."

Analogue Solutions Maximus 8-Voice Polysynth

"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."
