Additional Tone Tweakers Listings

"This unit was meticulously refurbished over approximately 16 hours, resulting in an instrument that works better than the rest...and is justifiably pricier, but is ready to use professionally. The person who sold us this unit said it was working fine, but in reality, it had several significant problems and needed a full and costly overhaul, including a $200 part (and others).

37383x

Here's a list of some of the work we did to this unit:

Cleaned unit inside and out.

Rebuilt power supply (replaced electrolytic capacitors) (future-proofing measure)
Replaced all electrolytic capacitors throughout unit (future-proofing measure)
Recalibrated. All ok.
Cleaned all potentiometers.
Cleaned all switches.
Cleaned all key contacts.

If you have one of these you’d like properly restored, we can help!"

Dave Rossum Joins Bob Moog Foundation Board of Directors



via The Bob Moog Foundation

"We are thrilled to welcome synthesizer pioneer Dave Rossum to the Board of Directors of the Bob Moog Foundation, the governing body our organization. Many of you know of Dave from his early days at E-mu Systems, and his more recent work through Rossum Electro-Music, but his work extends far beyond the companies that he has created. Dave's work in SSM chip design can be heard in the Prophet 5, Korg Polysix, Korg Mono/Poly, Fairlight II, PPG Wave 2, and many others. He also invented the polyphonic synthesizer keyboard.

Dave brings with him a wealth of creative and business expertise that will help drive the work of the Bob Moog Foundation forward. You can read more HERE."

Reminder: Minimoog Prototype Exhibit, Erik Norlander Keyboard Sale Price Drop, Mini Minimoogs & More



via The Bob Moog Foundation

Minimoog Prototype Exhibit At the Moogseum This Weekend Only!

The anticipation is almost over! We are thrilled to be hosting the Minimoog Prototype Exhibit at the Moogseum, this weekend only, in partnership with the Museum of Music Technology (MMT). The exhibit will feature four ultra rare Minimoog prototypes from 1969, 1970, and 1971, as well as a host of related artifacts from the Bob Moog Foundation Archives.

We are honored to have JoE Silva, author of The Minimoog Book: The Synthesizer That Changed Music Forever: Sounds, Stories, and Technology join us throughout the weekend of the exhibit. He'll be on hand to delve into the history of the Minimoog with exhibit attendees and sign books in the Moogseum store.

We're excited to share a new addition to the exhibit. MMT will be bringing Minimoog serial number 1016 (the sixteenth Minimoog ever produced out of 12,269 units), which was purchased in 1971 by none other than David VanKoevering, the marketing genius behind the early Minimoog sales. David's Minimoog will be available for exhibit attendees to play and explore. Come get you hands on this incredible piece of synthesizer history!

Finally, be sure to take advantage of the morning tours with our executive director, Michelle Moog-Koussa. Michelle will be delving into Minimoog history as it is conveyed through the main gallery of the Moogseum. She doesn't give tours often, so take advantage of this opportunity. The tours are available for a small fee for any exhibit attendee.

"Pretty good condition considering how old it is - the endcheeks have the usual minor damage on the corners but the panel, knobs, keys etc are very good. It needs a litle work* to be 100%: it has probably about 4 duff keys (will need re-coating with the special compound you can get) otherwise works over CV, Internally from what I remember, it has a slight crack on the pcb which had been patched up and resoldered by the previous owner. Few noisy pots etc."

Erik Norlander's Korg Mono/Poly Analog Synthesizer, serviced, with case SN 378257

Note: links to listings are affiliate links for which the site may be compensated.
video upload by moogfoundation



via this Reverb listing

"Very good condition, serviced by Rosen Sound, and includes a light-duty Tuff Case for easy transport!

Cosmetic notes: small chip in wood veneer edge under keybed, and the mod wheel shows a bit of wear. Both of these issues are shown in the images.

Released in 1981, the Korg Mono/Poly is known for its four VCOs, flexible modulation options, and unique mono/polyphonic switching, making it a versatile beast for both fat unison leads and unique, syncopated arpeggios. Its cross-modulation, oscillator sync, and deep routing options open the door to wild textures and sound design experimentation.

Specs & Highlights:

4 analog VCOs with independent tuning
Mono, Poly, and Unison modes
Crossmod, oscillator sync, and flexible LFO routing
Built-in arpeggiator and chord memory
Classic Korg 24dB/octave low-pass filter
Full MIDI retrofit kits available (not included, but easily added)
Used by artists like MGMT, Chromeo, and Jimmy Edgar, the Mono/Poly is a staple of vintage synth setups and prized for its unique voice architecture and beefy tone.

This unit was serviced by Rosen Sound, a trusted name in analog synth repair, so it’s running great and ready for action. Includes a Tuff Case (light-duty) to keep it safe during travel or storage.

30% of proceeds will benefit the Bob Moog Foundation, helping inspire future synth pioneers and preserve electronic music history."

The Florian Schneider Collection to Be Auctioned at JULIEN*S November 19

Note: links to listings are affiliate links for which the site may be compensated.


via JULIEN*S

"THE FLORIAN SCHNEIDER COLLECTION

Auction to be held at Musician's Hall of Fame & Museum, Nashville, on November 19

An incredible collection of more than 450 artifacts from the life and career of Florian Schneider, co-founder of the pioneer electronic band Kraftwerk."

Pics and videos featuring some of the gear below, and his Lederhosen for good measure (thanks greg!).

Update: the post has been fully updated with all the synth related gear. This may just well be the longest post to be featured on the site. I wanted to capture all the pics for all of the details including notes, scuffs, and of course serial numbers. It's an interesting look into what he used, the condition he keped his gear, in some cases, how he actually used his gear. Note the phonetics on the keys of the Casio CZ-101 and DX-100. Note the Midi Switch Box with a built-in speaker? What's that about? Note the camouflage key strap on the Korg RK-100 Remote Keyboard. Did he pick it out himself or did the keytar just come with it? Note the repeat midi controllers and the MIDI saxaphones. Wind was his primary instrument. You'll find a ton of the acoustic gear he used in the other listings. This is a fascinating insight into both what and how he used his gear.

Side note: there is no affiliate compensation for this post. The note at the top automatically shows for all posts with the Auction label.


Rack Mount Sennheiser VSM-201 Vocoder

Starting Bid $5,000

Estimate $20,000 - $40,000 USD

A late 1970s Sennheiser VSM 201 Vocoder with no serial number from the personal studio and collection of Florian Schneider of Kraftwerk (see images). While it’s said that only a few dozen of these Vocoders were produced, a few examples made it into the hands of forward-thinking musical artists including Herbie Hancock, Daft Punk, and of course, Kraftwerk, who used a VSM-201 like this on their albums Man Machine (1978) and Computerworld (1981). The VSM-201 has an intelligible sound that has not yet been bested by modern gear. Includes power cable. This VSM-201 has been removed from its wooden enclosure (which bears the serial number plate) and modified with a metal rack mount casing, presumably for live use. Requires 240v, IEC power cable not included.

Dimensions: 19 x 9 x 9 inches

Category: Kraftwerk, Equipment

Provenance: PROVENANCE From the Estate of Florian Schneider

Impact Soundworks Releases Chro-Nyx, New Virtual Synth Based on Classic Hardware


video upload by Impact Soundworks LLC



FULTON, MD – Impact Soundworks has released Chro-Nyx, a virtual synth that faithfully recreates the beloved JP-8080 synthesizer as well as elements from other popular hardware such as the Access Virus, Nord Modular 2, Korg Mono/Poly, Roland Jupiter-8, and others. With extensive oscillators, filter models, effects, and modulation capabilities, this virtual synth (available in VST, AU, and AAX formats via Reaktor Player) allows producers to create a huge range of possible tones.

Developed over the course of 5 years, Chro-Nyx captures the look, feel, and sound of the JP-8080, an early analog modeling synth that revolutionized digital music in the 1990s (most notably by introducing the supersaw oscillator).

Chro-Nyx then goes far beyond their original capabilities, integrating components from other vintage analog and digital hardware, along with unique and custom DSP, resulting in a feature-packed virtual synth workstation suitable for many genres.

Highlights of Chro-Nyx beyond the complete feature set of the JP-8080 include:

Dual oscillators with 31 oscillator types, each with unique parameters, and many emulating specific hardware

Dual filters with multiple topologies, slopes, and 5 styles available, such as ‘Classic’, ‘Acid’, ‘Lush’, etc.

18 filter drive types and a unique ‘BOOST’ mode that allows for extreme distortion and circuit bending-style effects

Dual LFOs that can go from extremely slow to audio rate speeds

Combination step sequencer and arpeggiator with optional trance gate

16-slot modulation matrix with Eurorack-style math sources also available

Dual effects slots with 29 modules available including shimmer reverbs, choruses, waveshapers, etc.

External audio input for processing through the full signal chain

Analog-modeled Pre and Post-FX EQs

8080-style vocoder with expanded controls, as well as 12-band resonant filterbank

Chro-Nyx was developed in partnership with Jasper Broeks (Chrono), a DJ, hardcore artist, and programmer who has worked with numerous well-known artists and performed at many festivals around the world. He creates his own synths under the Pulsecraft name.

“As an EDM musician myself, I’ve been collecting both softsynths and hardware for over 20 years, which is how I know that it takes a lot for a new synth to stand out. But having spent over 50 hours producing with Chro-Nyx, I’m in love, and I can’t wait to hear how other musicians use it!” CEO and owner Andrew Aversa said.

Chro-Nyx is available at the Impact Soundworks store for a limited-time introductory price of $79 (MSRP $99). Crossgrades are available for some customers.

Meet the M0SS 101 Synthesizer by Andrew John March




M0SS 101 DEMO video upload by Andrew March

"A quick demonstration on how to build a patch with the M0SS-101 synthesizer."



From the creator of WVR, the the M0SS 101 virtual analog monosynth is currently seeking funding on Kickstarter.

"M0SS-101 is a virtual analog monosynth built for a pure, hands-on subtractive synthesis, packed into a compact, rugged guitar pedal enclosure.

With 26 buttons and a single encoder, M0SS-101 gives you intuitive access to a deep 42-parameter virtual analog synthesis engine. Press a button to select a parameter, turn the encoder to modify it, and monitor your signal flow via the LED system.

Using a MIDI controller, you can map any parameter via simple MIDI learn, making it easy to integrate into your setup. Up to 17 presets can be saved and recalled for quick access to your favourite sounds.

The 26 RGB LEDs use colour and brightness to represent signal flow, modulation paths, settings and selections. A separate row of 11 LEDs at the bottom gives you instant visual feedback on the currently selected parameter. I aim to offer an affordable, compact, and versatile instrument, without sacrificing features, ergonomics, or most importantly, fun. I hope you'll enjoy playing this synth as much as I have :'-)"

"KORG Mono-Poly & Kovari Midipoly retrofit 372767 Original Korg Mono/Poly with Kovari MIDI retrofit - specifications available online New baseboard and custom plywood side panels Very tidy - camera shows every speck of dust Front panel Excellent All pots clean and noise free Voices fully functioning but will require calibration to ensure optimal output

DESCRIPTION: I acquired this fully functioning MonoPoly some years ago, but the case was in terrible condition. I cut a new baseboard from MDF, and then cut and installed new marine grade plywood side panels. The front panel is in great condition, but there is a slight defect on the mod wheel assembly panel as per the condition I acquired. All pots are noise free, as are the outputs. She sounds amazing in Poly Unison mode, but the individual voices do drift a little. She would benefit from a comprehensive voice calibration, but I don't have the instruments required to do so. Once she is fully calibrated, she will sound even more awesome. She comes with the Kovari MIDI retrofit, which allows her to integrate in to any modern MIDI studio. Very sorry to see her go, but I just don't have the space for my full hardware studio any more."
