CS5, Yamaha @ 22 September 2017, “No Comments”

“This unit was powered on and the (unwise) expectation was that sound could be heard through standard headphones. Wrong. The CS-5 needs to go through an amplifier (in this case, a “Block Rocker Max”) to be heard. Once connected to an amplifier, the CS-5 comes to life. The pulsing sounds are truly out of Logan’s Run, Styx, and so forth. It doesn’t play chords –nor it it supposed to; according to the manual, when more than one key is pressed, the CS-5 will give priority to the highest pitch. Furthermore, several YouTube demos were viewed and used to compare the functionality of this unit. Although the talented and experienced musicians online couldn’t be matched (there are thousands of settings), this CS-5 sounds like it should.” Link

DX-7, DX-7 II, Yamaha @ 22 September 2017, “No Comments”

“It is an exhibition of YAMAHA DX 7 IID body and bonus. (The power cord is directly attached.), The body memory contains DATA at the time of purchase.

Although there are scratches and scratches accompanying use, it is in good condition and beautiful for years.

I confirmed the operation, it did not malfunction of the button response, it worked normally. Basic preset sounds were output from all the keyboards.

For bonus, it will be a CD that contains over 210,000 sound data for the first DX 7. It can be sent from the PC to the main unit by MIDI transfer.

I think that it can be utilized preciously and widely.” Link

TF1, TX-816, Yamaha @ 22 September 2017, “No Comments”

“Yamaha TX 816 Tone Generator System Midi Synthesizer Rack with 8 TFI Modules (16 voices per module for a total of 128 voices) in very good condition with a few scratches on the top of the unit. Each TF1 module is a compact version of a complete Yamaha DX-7 Frequency Modulation engine. Each TF1 has an independent audio out (XLR) and MIDI I/O for a total of eight audio outputs and MIDI I/O’s. It also has one general MIDI I/O port. A real tank of an FM synth machine. Bid with confidence” Link

“In great working condition. Has all buttons, knobs, and power cord. ” Link

“It is in nearly great condition as you can see from the photos. Comes with two original disks, a handful of custom disks of my own, and digital copies of dozens of disk images. This particular sampler has had the 512K memory upgrade installed. There is a software editor available online.

Schematic and service manuals are available as PDFs, however this unit is in perfect working order – checked it out yesterday.

I believe this sampler is a hidden gem, sounds just as good if not better compared with EMU Emulator II. Feature and sound-wise one of the best designed samplers and sound quality. It also has a very nice MIDI arpeggiator that is unique. Leave it to Dave Smith for the ingenuity of this beast.” Link

“Up for auction is a Sequential Circuits Six-Trak vintage analog synthesizer. This model is notable for being one of the first multi-timbral synths, equipped with MIDI and an on-board six-track digital sequencer. The unit is fully functional with one exception; track 5 does not work. Everything else on the synth is good. Physically it’s in good shape, with a repaired crack in the wood (see pics). Other than that it just has a few minor cosmetic marks here and there, typical of a 30 year old used piece of gear. ” Link

“Selling a rare Sequential Circuits Prophet VS Digital Vector Synthesizer. In very good condittion..” Link

“The unit is working but selling as is for parts, refurbishing. All keys and functions seem to be working. I did not check the midi ports. The on/off switch works but is incredibly hard to turn on/off. It appears someone replaced the audio out jack. It is missing one knob for speed and shows wear, notably some rust, a chip in the wood on one side, and upon close inspection the black keys on the left of the board are chipped in the back (where you can’t see) where there should be full “hooks” if you will that prevent the black keys from sliding or popping out of place. They are seated fine and don’t move at all but if they were pulled on they would dislodge-it’s easy to put them back and again, they are in place firmly and all work just fine. Rubber of the power cord at exit in back is frayed but internal wiring appears ok and provides power but power cord might need replaced. Overall cosmetics aren’t great but seems the electronics are good. Selling as is for parts, repair or refurbishing. (I’ll try to put up a video tomorrow so you can hear it).” Link

“Up for auction is a sequential circuits prophet T8 polyphonic analog synthesizer keyboard parts/ repair as is. I’m going to attempt to list all the things that are functioning/ not functioning. This keyboard probably needs a few thousand dollars to get it up and running.

Pieces that are missing/ not functioning :

5 screws in the back

22 knobs

The original pot on the frequency knob on the Lfo – mod section. It does have another pot on their at the moment, that does work… Its just not the original pot.

The switch on the freq A on the Lfo – mod section doesn’t turn on. Let me rephrase this, it turns on if it is included on a certain preset. But it doesn’t switch on.


The first four keys on the lowest octave are warped and stuck together.

53 out 76 keys work

When you plug in a midi keyboard all the keys work great

What works:

The sequencer

The presets have been currently installed

All the keys work via midi

The after touch

All eight voices are working

all of the knobs and switches work except for the frequency A switch on the Lfo mod

The tuning button works

Modifications/ Repairs

I painted/ stained all the wood on the sides on the front and in the middle of the keyboard.

I painted the top portion of the Prophet black

I replaced two of the Voice chips

I replaced the internal battery and I installed all the factory sounds” Link

“I am selling the amazing and beloved Sequential Circuits Six-Trak. I have owned this Synth for about 2 years and have upgraded various areas of the Synth. Despite some minor cosmetic scuff marks due to its age, this Six-Trak is in pretty good shape. The right wooden side panel is broken and is something that can be fixed easily by applying some wood clue or by buying new wooden side panels for only $60 on “gmusynth” Some of the key features for my particular version of the Synth are.

1. Multiple Outs! This synth was modded so that all voices have their own output on the back. (AWESOME!)
2. I recently upgraded the Firmware from v9 to the latest version from tauntek v14.
3. Fixed some of the broken keys, (cosmetics)
4. Bought a new knob cap for the main volume knob (which I haven’t attached yet because the new knob cap needs to be modified, cosmetics)

You can read up on the new firmware version by googling tauntek SixTrackBug. This firmware version fixes a lot of the parameter issues with previous versions and adds some new features.” Link

“Selling our Prophet 2000 Keyboard sampler. It has the maximized 512K memory and an upgraded hard drive. It functions perfectly and is in great condition. Has a few marks on the surface but minimal wear for its age. Comes with an SKB I Series waterproof case.

We have made awesome sounds with this. For any questions we’ve been in touch with the people at Sequential Circuits and they’ve always helped us with the programming.

The Prophet has analog VCF’s and VCA’s which give you analog tweak-control over the sounds you sample. It has 8 voices of polyphony, the keyboard can be split into 8 layers, MIDI equipped, and there is an arpeggiator.”

ARP, Omni @ 20 September 2017, “No Comments”

” The Arp Omni is a 40-year old vintage synth now prized for it’s string sounds. This unit has been in storage for 20 years, but unfortunately only powers on, does not produce sound. Attempted to clean slider pots and installed ~30 new capacitors, but not expert enough to fix the unit.

What’s included:
– the Omni itself
– custom canvas case
– original owner’s manual (cover torn but the rest in tact)
– original spec sheet
– collector’s special–the original 33RPM vinyl demo record and accompanying poster

If you’re not an expert technician and know this model i would not recommend purchasing this—the solder joints appear to need rework by a professional, and this model requires specific knowledge and parts to repair. That said, once working, these are now rare and command a high price.” Link

“Rare Kawai SX-210 Synthesizer Excellent Condition Not working with repair kit

This a very rare Kawai SX-210 Synthesizer from a studio sale

All the keys and buttons feel right and the overall appearance of the unit is in excellent condition.

Typical battery leakage failure on main board. See picture, tracings have been tested with ohmeter and are conductive

Old battery has been removed and the last custom CPU repair kit from Portugal is included with it.

I have no time to fix this myself. All nearby components including rare CPU are included in the kit along with instructions for tech repair

No other way to test this so it is sold as is for parts or repair” Link

Includes iProgram Card, preset cards, BEMI bag with shorting bars and cables and original box.
Works well and is in nice condition. Sold as-is, as seen. No returns. I add this caveat because on forums people constantly gripe about BEMI/Buchla and pick at minor (and sometimes major) imperfections. ” Link

“Harvestman Stillsom Hammer MK1. No this is not the mk2 quad sequencer. It is a burst gen, with all sorts of strange functionality, and can be used a trigger sequencer, a weird gate, and an assortment of other functions depending on the CV input. It can be patched to create a sequencer by using a mixer, which can be fairly interesting if you use the random/pendulum functions.

You may notice that it has been updated with new knobs for aesthetic consistency with MK2 modules, these were purchased directly from the Harvestman/Industrial Music Electronics. If you want the old-style knobs, let me know. No original box. Serial #130.” Link

All knobs, sliders, buttons and switches are present, original and function correctly.

The unit has been fully tested, a new backlight installed, calibration procedure checked and the oscillator tuning and scaling confirmed. ” Link

“DESCRIPTION : This listing is for a Oberheim OB-8 Analog 61 Note Keyboard Synthesizer.

This machine just came to us from Rosen Sound here in Burbank. It has been fully serviced, cleaned and prepared for flawless operation for years to come.

ACCESSORIES : Includes a power cord. Otherwise, this item comes only as seen on photos.

PHYSICAL CONDITION : Very Good. The wood side panels were just re-finished by Rosen Sound here in Burbank. So they are immaculate. This unit has light scratches and a bit of wear on the metal exterior, but all the text around for the parameters and the visual touches are in great shape. Sturdy and in fine condition overall!

WORKING CONDITION : Excellent. Works wonderfully! Phenomenal sound quality and stellar functionality across the board, whether playing rapid runs and arpeggios or droning textures. Lovely sound, smooth playability, and fantastic operation!” Link

A couple keys need cleaning due to only used through midi past 10 years. If you are looking at this auction you already know what this is and its unmistakable sound and earth shattering bass. If I track key bass, its this or mini moog period. Lush pads and each voice can be assigned a position in the stereo field so its huge!!!” Link

Q, Waldorf @ 19 September 2017, “No Comments”

“Amazing, great sounding, deep synth. Acclaimed by many.

It works well except for the pots / encoders, some of which are jumpy. I enjoy the synth and find it playable as is, but if the buyer wants the synth fully functional, the pots / encoders would need to be cleaned and/or replaced.

Check out the photos as the case shows a good amount of cosmetic wear. Also note that some of the rubber knobs have cracked / split (a few of which have been saved in a baggie, included).

Includes power cord.” Link
