Bad Gear - Multi/Poly
video upload by AudioPilz
"Welcome to Bad Gear, the show about the world’s most-hated audio tools. When taken out of historical context it might currently seem like a bunch of big companies are stealing the ideas of a Swiss/German/Chinese innovator and trying to amateurishly emulate them in digital form to make a quick buck.
Today we are going to talk about Korg multi/poly. This virtual analog synth and Raspberry Pi in disguise asking you politely to take it out of its misery not only looks like an AI-generated picture-to-CAD rendering conversion process gone wrong, it also comes with more features than a marketing blurb can handle.

"Vintage ARP 2500 Modular Synthesizer system. Accompanying the ARP 2500 main cabinet is a pair of fully loaded wing cabinets. The main cabinet and keyboard were fully restored by Phil Cirocco (CMS) around 2011 as well were most of the modules in the wing cabinets. However the system has not been powered up or played since 2018 when I moved from Los Angeles to Tucson Arizona. It was working perfectly in 2018. Since sitting for 7 years the system will most likely need some small service to get it back to perfect. IT IS UNTESTED AND WILL NOT BE TESTED. IT IS BEING SOLD AS IS.
The previous service was meticulously done to satisfy my serious demand for the system to remain as original as possible. No modifications were done and all parts replaced with original or appropriate parts. The system is hyper clean in person and was clearly babied. It was used on notable lp's. You may live a 100 more years but will likely never find a better more complete ARP 2500 for sale. This system is priceless and was the most expensive new instrument when it was produced in the early 1970's.
I collected and played many Moog, ARP and Buchla modular systems. However owning so many systems became a burden. As well, switching between using Moog, ARP and Buchla took too much bandwidth. I sold all of my Buchla systems and this is my last and best ARP piece from my massive collection. Time for someone else to own it
CAN BE PICKED UP IN TUCSON AZ OR I CAN DELIVER TO LOS ANGELES CA"

"This is fully serviced. All power supply large filter caps replaced, the ground connection from the molex a known failure mode has been tied permanently.
For H910 mode hit the 'algo' button and it will remove the 'deglitch'.
Memory chips, brand new, changed to ones that only run on 5v rail and not three different rails, they run much cooler, also when something goes wrong they don't get cooked. The early DRAMS used by eventide, those that were available were failure prone - the Personal Computer revolution quickly led to better DRAMS - which are deployed in this unit.
Electrolytic caps, tested, replaced for low ESR - top quality the best available
Better quality ceramic capacitors around DRAMS to drop noise floor to the lowest possible. They are mil-spec about £3.50 each for a tiny component and there are 10 of them.
Ripple checked for lowest noise performance possible
Tantalum where there should be tantalum - again the best.
Heatsink compound applied
A lot of the character of this unit comes from two factors; one the early digital use of memory chips to store the audio delay line with ultra fast bit slicing AMD bipolar processing chips and two the DBX companding (x3) - these really resolve the noise associated with early digital and improve signal to noise."

"Fully polyphonic 48 key analog string synth. Classic 70's string/ensemble synth sounds. Amazingly thick, and warm sounding- sounds huge and dreamy. Used by Jean-Michel Jarre, Tangerine Dream, Vangelis, Hawkwind.
Works great. Voice selection buttons/switch contacts recently cleaned, and working well. Built in case has new latches installed.
Treble eq control is very scratchy, but works once set. Some of the other pots may be slightly scratchy, but all work. Light on power button does not light up- power switch is functional- unit powers on/off, but light doesn't work. Scratches/nicks on top (top is great for stacking other gear on).
I've had the pleasure of owning this beast for 20 years- it's gotten a good amount of use, but has been well taken care of, and rarely taken out of the house.
Stacks 3 oscillators per key/voice in octaves- you can also turn two of the oscillators on or off to use two or one oscillator per key/voice. Can also detune two of the oscillators separately to create a thicker, layered sound. Buttons/switches for selecting sounds can be simultaneously pressed to stack sounds. Built in phazer sounds excellent."
