CS15 w/ Don Solaris mods & Yam Case

Click the auction link on top when you get there for additional listings.

Here’s Yamaha’s classic duophonic (with a little effort) synthesizer with Don Solaris’ mods to facilitate chaining the VCFs for something closer to a 24db/octave response. There’s also a mod to the LFO’s rate control to get better use of it at audio rates - a welcome addition to the CS-15’s already pleasing sound palette. All told, the mods make a good sounding, but somewhat limited instrument rather less limited! It’s in great condition for a synth of this vintage, and was serviced a few years ago by the same techs who performed the mods. The sliders don’t have a “buttery smooth” glide, but are silent, as are the pots. I hear a very, very faint crosstalk between filters while the serial mod is not engaged, and I can’t say whether it’s due to the modification or, as with my old CS30, it’s part of the synth. It’s not noticeable in practical use, but if you’re actively looking for behaviors like this, you might hear it. It’s also like a 50 year old keyboard, so… I would rather have the single-voice CS-30 with its modulation possibilities, but I also just don’t have the space anymore. Please find the details of the mods here: https://greatsynthesizers.com/wp/wp-content/uploads/2019/07/cs-15_mods_DonSolaris.pdf Will ship from Berlin, Germany in its Yamaha-branded hard case.

Formanta P432 + LELMIDIDRUM From UltraRare.SU

video upload by Futulyric

"The Formanta P432, a Soviet digital synthesizer, originally featured a very distinctive, authentic noise and could have been significantly improved if it had supported ADSR. This flaw has now been corrected; as a plugin, it sounds more interesting. The noise, however, remains, lending a distinctive vibe.
LEL MIDIDRUM is a digital drum module from the company of the same name, dating back to the Soviet era. No other surviving example is known, so its sound can only be heard here.
Also available as a plugin.

Synthesizing with Moog | Lesson 4: Original Soundtrack

video upload by Moog Music

"The soundtrack from the fourth episode of Synthesizing with Moog invites you to dive deep into one of the synthesizers signature components, the Voltage-Controlled Filter. While different oscillator shapes could create a bed of tone and harmonics, the Voltage-Controlled Filter allowed musicians to sculpt a distinct sound out of all those harmonics and even shape that sound over time.

We hope you enjoy this music created by Moog electronic musical instrument experts Max Ravitz ( / patriciaaa ) and Gunnar Haslam ( @lasynthesehumaine6932 ).

"The soundtrack from the third episode of Synthesizing with Moog invites you to dive deep into 'Vibrations' and their the source on the synthesizer – the oscillator. We also dive into the topics of harmonics, looking at how the shape of oscillation creates distinct tones with different harmonic characteristics.

Anthony Marinelli Music Synth Studio Revealed | Studio Tour 2025

video upload by Anthony Marinelli Music

"I finally agreed to make a video showing my synthesizer studio. I'm NOT a collector, so you'll see the instruments I've used for over four decades to do my work. It's also my space for composing. In this deep dive studio tour, I walk you through every corner of my space, showing how everything’s connected for performing, recording, and creative flow.

You’ll see icons like the 'Plantasia' Moog Modular IIIc, Synclavier II, Rhodes Chroma with Expander & Enabler, Oberheim Four Voice, Elka Synthex, Roland Jupiter 8, Sequential Circuits Prophet-5, ARP 2600s, Korg MS modular synths, some classic Minimoog — plus a few modern synths I’ve added as I look to the future. Alongside the synths are vintage drum machines, string machines, and rare electric keyboards including a 1973 Fender Rhodes Suitcase and Hohner Clavinet/Pianet Duo.

We'll also explore racks of outboard gear, vocoder units, tape echoes, and a vast array of my custom guitar pedal options, efx pedal boards and studio effects racks that make this room endlessly inspiring. I'll also reveal how my entire studio is designed for instant creativity, featuring 48 channels of synth drivers and stage boxes, so any synth can be patched and recorded on the fly."

PPG Synthesizer 1020 with Servicing

Click the auction link on top when you get there for additional listings.

"This ultra-rare early PPG monosynth's overall condition is very good, and it is great-sounding. But there is one problem: VCO 2 is quiet via the internal mixer, however the input to the Ring Mod is working perfectly. This makes me think it’s something relatively simple in the mixer rather than an issue with the oscillator…. fingers crossed! VEMIA will collect after the auction and service it fully at the seller's expense. All you need to know about it (and more) is here…
It is of course labelled Palm Products Germany - hence PPG. VEMIA will collect for servicing, and then pack: 30GBP."

"Released in 1978, this monophonic 32-key analog synthesizer is a one-oscillator version of the MS-20.
It is a model with a simple structure, but the fat bass, easy handling, and compact and lovely looks make it a famous instrument used by many artists even today.
All parts have been maintained.
Item rank: B : Fairly scratched and used, but no problem in normal use."
