“This Item is being sold as FOR PARTS OR NOT WORKING

Please be fully aware. . This unit is being sold with the following 5 description statements ONLY. . .

1/ This unit does NOT work, and is sold for parts, or for someone to repair or get the unit repaired.

2/ This is a complete unit (all original parts, case never been opened since I’ve had it, and the unit worked when I bought it in 2001). The physical condition as shown in the photos. Some of the writing on the unit is worn, and there are lots of small scratches and small worn features all about the case; all of which can be seen in the photos (please zoom in on the photos for a close inspection.) The unit’s in the condition that it came to me, it’s had no rough treatment from me, and has been stored in a bedroom since 2002.

3/ The unit powers up, meaning the LCD display comes on, when unit switched on.

4/ There is no sound coming out of any of the outputs.

5/ The 3 ROM cards were, and have always been, plugged into the unit since I bought it in 2001. (The unit worked ok when I bought it in 2001, including the ROM cards. Since 2002 the unit has been stored in a bedroom in my house). I unplugged the ROM cards 2 days ago for the photos taken for this listing. They seem in fair condition and show no visual signs that they may be physically damaged (cracks or damage due to impact etc..), I could not test them as the unit would not work when I tested it. I cannot therefore guarentee that they work, so they are being sold as UNTESTED.” Click here to visit listing on eBay

Korg MS2000

“This is a Korg MS2000 modeling synthesizer, vintage original with original box.
Nice synth, big fat sounds but a few problems.
The left and right outputs do not work, I think this is down to dry solder, so I used the headphone output which is situated on the front left of the synth (see pics).
Also the input where you plug in the power supply needs a wiggle, but it does work.
This is a great synth but needs a bit of TLC.
Reason for selling is I’ve bought a new synth.
This MS2000 also has the original manual and box.” Click here to visit listing on eBay

Korg 770

“The 770 is a very early, very cool Korg synth, but you probably know that or you wouldn’t be looking.
White noise, tuned noise, 2 different ring modulator modes, 2 oscillators, High and Low Pass filters.

The great thing about these is they sound like nothing else. If you’re an analog synth guy who already has the normal stuff, this definitely opens up another range of sounds you can create. In fact you can go inside the unit and tweak trim pots to alter the behavior of the filters! You can also run external audio through them. It has a mean, raw sound that later pieces like MS20 can only dream of!

The only issue with this is the auto bending feature doesn’t work consistently, but it isn’t broken. The portamento is more musical and works fine. Apparently it was used near some spray paint as there is some on the right end cheek and a very subtle amount on the far right side of the control panel, but unless you’re staring at it under bright light you won’t even notice.” Click here to visit listing on eBay

Classic FM-Sounds

Still has Euro plug, with which it shipped: I’ve never felt the need to change it, as it slips nicely into a plug board (see photos): You could easily use a euro adapter if required.

Listed as collection only, as it’s pretty heavy, though would consider posting at buyer’s cost.”

Yamaha DX100

“I purchased this DX100 new in 1985 with every intention of becoming the next Rick Wakeman or Keith Emerson until I discovered I was too lazy to practice and resorted instead to making sound effects for my answering machine messages. Shortly after, it took up residency in my bedroom closet where it remained until now nearly 40 years later. It is in near new condition with every function working and no noise from the pots once I sprayed them with contact cleaner. It was never stored with batteries installed and has been kept in a non-smoking environment. AC Power supply is included.” Click here to visit listing on eBay

Yamaha Tenori On

“Box, power adapter, MIDI cable, and media card are all included, but I lost the user manual years ago. The manual is easily found online, and there is no programming difference between TNR-O (this model) and the TNR-W (with the LED panel on the back). I upgraded the software to the most recent firmware, and these are out of production.
The Tenori-On is an intuitive sequencer with some decent sound sets, and includes MIDI implementation for sequencing other synthesizers. Most sounds are modifiable (to some degree) which makes it more/ less chiptune.

The real fun part is the sequencing modes and layers, which can yield interesting polyrhythms.

If you think of each layer as a “pattern” on a typical sequencer, you can switch between programmed layers to create a “song”.” Click here to visit listing on eBay

Yamaha CX5M

“Yamaha CX5M is an MSX-system compatible computer with a built-in eight-voice FM synthesizer module.

This FM synth itself has stereo audio outputs, an input for a purpose-built four-octave keyboard (not included) and a pair of MIDI Input/Output ports.

Waldorf Blofeld

“Waldorf Blofeld Desktop Synthesizer – White (Used, under 4hrs use!) w/ dust cover. Condition is “Used”.

Bought this 2/1/2021. First unit had an issue, got it replaced by the original distributor. Used this unit (the new replacement) for about four hours. Works flawlessly. Alas, my sound design style and technical requirements and this unit’s specs are not really compatible with each other, and I’m just not gelling with the unit. I could tell this after 3.5-4hrs of use, and haven’t used it since. I’d rather it find a good home where it will be used regularly and enjoyed. It has been babied, and is in mint condition, with under 4hrs of use on it.

It’s been flashed to the latest 1.25 firmware. Does -not- have the extra SL license that Waldorf sells separately, as I didn’t use it enough to warrant purchasing that extra add-on. (The desktop model doesn’t come with that license.)

Includes the original power adapter from Waldorf. I do not have the foreign power adapters any longer, as I didn’t need them, nor did I keep the original box. Will package well for shpment via USPS Priority Mail.”
