Yamaha CS01

‘Up for auction is a Yamaha CS01 Analogue Synthesizer. If you know about these, you will know that this is not just any old mini keyboard, but a true analogue synthesizer in miniature, portable form. As such, these have been used by many famous musicians, including the Dust Brothers, Underworld, OMD, Richard Barbieri and Chick Corea.

It features a volume knob with power on/off switch, twin controls for the breath controller to apply it to either the VCF, or the VCA, or both in any combination (the input socket for the breath controller is situated on the left side of the synth). Note I am also listing a Yamaha BC1 Breath Controller, the correct one for this synth, in a separate auction. There are Pitch Bend and Modulation wheels, and the Modulation can affect either the VCO or the VCF. There is an LFO with Speed control. Next are the VCO controls, with a slider for Glissando (like Portamento, except that it moves in discrete semitone steps), Pitch slider, Feet multiswitch (with 32′, 16′, 8′ and 4’ settings, plus White Noise). Next is the Wave multiswitch, which selects between various waveforms, plus PWM. The PWM Speed slider is next (see note below about this), and that completes the VCO section.

Next is the VCF, with controls for FREQ CUT OFF, EG DEPTH, and a RESONANCE high or low switch. This is followed by an EG DEPTH slider for the VCA, and finally, towards the right end of the panel, are a set of traditional ADSR sliders for envelope control.

The above represent the standard controls of any conventional analogue monosynth, and anyone familiar with Moogs or similar will be immediately at home with this instrument.

This particular unit was bought for use in my personal studio, and has not been used on stage. It was always well looked after, and kept in the soft padded case it will arrive in. As a result, it is in excellent, barely used condition. I have checked it for faults, and everything is working properly, apart from the PWM Speed slider, which has no effect on the sound at all. Other than that, I would rate it at 100 percent. The starting price has been set with this in mind, and with no reserve this will be a bargain for someone.” Click here to visit listing on eBay

Yamaha DX27

“*the only thing wrong with this DX27 is the error code ‘CNG RAM BATTERY’, which means the CR2302 that is the backup battery for the on-board RAM has gone dead. This can be a very simple battery replacement for someone in the know.

Comes in hard case along with original power supply (with a plug change to bring it up to todays standards) as well as music book sheet bracket, introduction book, voice programming book and owners manual.

Otherwise the DX27 is in a very good condition overall with minimal cosmetic wear and otherwise working great. The synth has spent a long time in the case away from the elements so it hasn’t sustained discolouration on the keys and body.”

Selling this lovely dark horse of a synth from the 70s. This thing is very underrated, sounds huge and has a lovely bottom end. Two of everything – oscillators, filters and envelopes.

In fantastic condition, all pots and switches cleaned. Everything tested and working perfectly. It hasn’t been used much recently (hence sale) as I have got my cs-60 back from repair so that has taken over.

Yamaha DX7

“Description: Up for auction is a classic Yamaha DX7 Synthesizer in good working condition, despite a few minor cosmetic issues.

This Yamaha DX7 is in good overall condition and working as intended. However, there are a few small issues to note:

Membrane cracks: Two buttons on the front panel have cracked membranes, leaving them exposed. The buttons still function properly, although they feel slightly less responsive compared to the others.
Key damage: Three keys have cosmetic damage due to melting. However, these imperfections do not affect the performance or playability of the keyboard.

Included Accessories:

Two ROM Cartridges: Comes with two additional ROM cartridges, “Rom Card 1 Master Group” and “Rom Card 2 Orchestral Sounds.”

.

Additionally, this listing includes a windcontroller, a unique accessory that allows you to control the synthesizer using breath control. I have not been able to successfully program the DX7 to recognize the windcontroller, but it is apparently functional.

After testing all keys, buttons, and cartridges, I can confirm that everything seems to be working.” Click here to visit listing on eBay

Yamaha SK20

“For auction is a vintage Yamaha SK20 analogue synthesiser. It’s one of the combined organ/synth/string machines characteristic of the mid to late 70s. A full description appears on the Vintage Synth Explorer Site and there are a couple of demos on YouTube. It’s similar to but different from, synths like the ARP Omni, Roland RS 505 etc. etc. and somewhat rare these days.

It includes a very effective (for its time) Leslie simulation and ensemble effect which produces the classic string synth sound. Limitations of 70s technology however mean the Leslie and ensemble effects can’t be run simultaneously but there’s nothing to stop use of external processing (I suggest an external Leslie pedal on the organ output such as a Korg G4 so you can use the ensemble effect on the strings and synth). There is also a rear output for connection to a real Leslie speaker but I’ve never been able to test this as I have no access to a cabinet.

Everything else works fine, but please bear in mind it’s over 40 years old. These synths are capable of producing some very haunting sounds when run through external effects and sound nothing like modern instruments. I found it works particularly well with the new Boss Dimension C pedal left on its ‘D’ setting.

The synth section is rudimentary compared to what’s available today and it’s paraphonic as opposed to truly polyphonic. It’s very useable however and as is typical of these keyboards, shines when the different layers are combined. The organ section is excellent in my opinion, particularly given its age.

This is a Japanese model and therefore operates on 100V. It runs quite happily off a small step-down auto-transformer which I’ll include.” Click here to visit listing on eBay

Yamaha CS-30L

” This is a very rare chance to get one of the coolest, weirdest, quirkiest and most amazing non modular that sounds like a modular synth…whew. This is my CS30L.

About this CS30… It is indeed fully functional, everything works and its in tune just fine. I spent a couple hours on it this morning… its sounds amazing and yes it all works.

If you read online about this synth, you’ll fine the same verbage and thoughts. It is unlike ANY other synth… the architecture is very different than any other synth, so if youve never played a CS30, you’ll find yourself saying “huh??? What is that?… a LOT.
Its very much like a modular synth in design and in labeling without the cable patching. The modulation routing alone is mind blowing… you can modulate just about anything in spades… 3, 4, 5 ways of modulating major sections of the synth AT THE SAME TIME… yes, its deep. There are too many cool things of this synth that are unlike any other.” Click here to visit listing on eBay

This may be for parts as everything else seems to work fine. Oh, the George L 1/4″ cord doesn’t go, nor the Peavey amp its sitting on. The power supply does not go with this keyboard, it goes with another SY-35 that I will be selling. I thought I had two power supplies, but I can’t find but this one that goes with the other keyboard. It does include one peddle, I think a sustain? I am in the central Willamette Valley in Oregon, so if you are somewhat local that would be good to pick it up, but I’ll hire the mail service people to box this to ship otherwise.” Click here to visit listing on eBay
