7/10/23 (alternate take) DIY Ray Wilson / MFOS synthesizer + Zerosum Inertia 6AS6 + Metasonix R-57
video upload by
"This video contains more filter sweeps than the video previously posted on 7/10/23, and the MFOS filter cutoff settings cause the Zerosum Inertia 6AS6 Signal Combiner to generate different rhythms than in the previous video. Two MFOS LFOs (at audio rate) go to Zerosum Inertia 6AS6, get combined, go to the MFOS filter, and go one channel on the R-57."

"Near-mint condition Korg Trident mkI synth. Paint and silkscreen is mint. The wooden cabinet has some minor scrapes and dents that I tried to capture as best as possible in the photo, but nothing major. The synth was just fully serviced by Bell Tone Synthworks in Philadelphia, which included the following -
Replaced power supply capacitors, rectifiers, regulators
Replaced all Matsushita capacitors
Cleaned pots
Tuned voices / calibrated antilog, power supply and resonance circuits
Tested all functions
Additionally, the keybed feels fantastic with no faulty keys. Overall, this is a near collector-grade Korg Trident. As for the wood cabinet, some touch-up with a furniture pen would truly minimize any visible faults. As an FYI, upon check-in to BellTone, the synth showed no faults, but because the Matsushita capacitors are known to be out of original tolerances at this point in time, I felt it was necessary to do. In all, I spent $1200 in preventative maintenance on this Trident for its future owner."

Never Released Korg MU-5000 (Japan, 1985) Vintage Music Synthesizer PC Prototype

via this auction
SN ES 850111
"In 1985 Korg decided to challenge the personal computer market creating a competitor for the legendary Commodore 64 (which was born three years earlier, in 1982).
Rumors then began to circulate about a new musical personal computer signed by Korg, called KORG MC-4000.
Along with the Korg MC-4000, Korg had designed 2 units which were extra and integral parts of the personal computer: a music synth expander called Korg MU-5000 and a microdisk unit called Korg MF-1000.
The incredible fact is that the personal computer project signed by Korg (the first “musical” personal computer in history) has remained for many years as a fake, since none of these products has ever been marketed in the western world.
The only historical artifact related to this project is a Japanese advertisement, a printed ad by Ishibashi Gakki released in the April 1985 issue of “Keyboard Magazine”.
In this ad (please, see the original photos), there were showed 3 products: KORG MC-4000, KORG MU-5000 and KORG MF-1000. The KORG MC-4000 music computer was then presented as a "compact computer containing its own music system".
Korg MC-4000, Korg MU-5000 and Korg MF-1000, according to historical information, have never been marketed because then Korg decided not to challenge the personal computer market. We don't know why!
Today, after years of research, we at Re Seller are pleased to present you the only survivor in the world of that super cool project: the original KORG MU-5000 expander synth!
This find of ours is of fundamental importance as it demonstrates that the Korg music personal computer project would have been really close to being commercialized!
This impossible to find Korg MU-5000 has been tested and is still in working order! Cosmetically there are minor signs of wear due to age, but nothing serious. The power supply is compatible and is included in the sale (this unit works with any 9V power supply and center negative polarity).
This small desktop synth contains beautiful sounds at its core! It is a 16-channel midi expander capable of generating some mighty impressive sounds courtesy of the same Digital Waveform Generator System used in the DW6000 and in the best Korg sounds of the 80s!
What we were able to test is very easy: we connected a midi keyboard to the Korg MU-5000 and listened to 128 sounds preset via program change (we changed the program change directly on the MIDI keyboard).
There are probably many more features to discover, but we don't have the capabilities to test it 100%!
An incredible piece of history, for the most demanding collectors in the world. Impossible to find another in all of history!"

Dynacord Percuter (Germany, 1985) Rare Vintage Drum Synth Trigger with 6 Cards
Note: Auction links are affiliate links for which the site may be compensated.
via this auction
You can find demos of one in previous posts here.
"Ultra rare electronic vintage drum synth trigger module Dynacord Percuter, made in Germany in 1985!
The Dynacord Percuter has 8 channels all with individual outputs/inputs and uses Dynacord cartridges with 8K eProms inside: if you have imagination you will work out how to exchange the eProms and customize your electronic drum sounds!
The only knob that doesn't work in the unit is the pan knob for the channel 1: the channel 1 works perfectly, only the “pan” (right/left) doesn't work in this channel (it probably just needs to be cleaned or the potentiometer needs to be replaced: we are not technicians). Everything else works perfectly!
Drum sounds can be pitched up and down with the pitch knob!
Totally analog unit, with really fat and super cool sounds!
It comes with the following 6 cartridges:
• Natural Rimshot
• Natural Snare 8”
• Natural Tom 13”
• Natural Tom 16”
• Natural Bass 22”
• No Name"
