Kawai, SX-210 @ 20 November 2018, Comments Off on Kawai SX-210

“No RAM battery – the synth will not boot up into the normal playing mode and does not make any sound, but I can still access the maintenance/adjustment features by playing the lowest C Major chord while turning it on, so it seems to still be alive. The panel test is is actually running in the first photo – that’s why all the lights are on.In addition, I did notice some corrosion on the circuit board around the battery, but it never seemed to impact the functionality before I removed that battery. Please see the pictures for the extent of the corrosion. Because of the missing battery and corrosion, I’m selling this for repair/parts despite that fact it was working fine with a battery.Cosmetically, the “BANK D” button is missing its plastic cap, and a G key is chipped and cracked. These still seem to work though. Typical scuffs” Click here to visit listing on eBay

“The Kawai SX-210 is a very rare synth. It’s an 8 voice poly synth with 4 poly stack mode as well as mono mode and chord mode. Built in chorus gives you the ability to hit those Juno sounds as well as polysix/MonoPoly sounds. It’s got Sub Osc, PWM, LFO routing/trigger and more. It’s a very capable and great sounding synth. It has a very large patch name display which is unique as it lets you write words for patch names rather than just a 2 or 3 digit number.

This is probably the best condition you’ll ever find one of these in.

Issues: The only physical flaw is on the wood side panel on the front tip there’s a crack besides normal wear. This doesn’t effect the functionality at all and could easily be replaced with new sides. The synth itself is great condition. Prior to shipping I will send a video showing functionality and you will give the OK before shipment. The Ensemble (chorus) button when enabled can cause some gain boost.” Click here to visit listing on eBay

” Unit works with all 8 voices. However, banks A and B seem to have different issues. I do not know the problem but they are intermittent when selecting patches. Banks C and D look to function Ok as far as I can tell. It looks like all of the parameter functions also operate. I do not know anything about this unit as far as repairing it.

sx210 “I found this rare and excellent condition Vintage Kawai SX-210 Polysonic Synthesizer\analog keyboard at a local estate sale. This keyboard has been tested and works and sounds great! Very low start price on this professional full size analog keyboard. These were produced in the early 1980s by Kasai and are exceedingly hard to find. True analog sound from this vintage full sized Kawai soundboard. This was found at the estate of a local musician and has been very well cared for. This 61 key poly sonic synthesizer shows a little wear to the woodgrain sides as shown in pictures but is otherwise clean a works perfectly, producing clean a clear true analog sound. See all pictures. All original keys buttons and dials. Previous owner stated that he has never had any issues with this keyboard and was the original owner. These keyboard are very rare and very desirable to musicians as they are no longer produced This keyboard weighs about 28 pounds and I am extimating the shipping weight to be 30-31 lbs. All functions tested and working as designed and intended. No excessive slack or play in modulation wheel or pitch/bend bar. The only wear noticed upon inspection is a slight canting of the 32nd and 58th keys. Might be an easy fix at a music shop but keys work fine, they just hit the keys next to them (left and right respectively. No other issues but some cosmetic wear as to be expected for a 35 year old vintage price. All original down to the cord. This full sized keyboard measures 34 3/4″ inches long and is 6″ tall with knobs. Case measured 15 3/4″ deep from back to front. Very clean example that was well cared for and properly stored by the previous owner.” Click here to visit listing on eBay

Kawai SX-210 “Rare analog poly synth manufactured in 1983. No midi because this keyboard came out right before midi was available. Great sounding DCOs, very versatile synth with sub oscillator, poly 8, poly 4, or mono. All functions work EXCEPT some of the preset buttons.

Some issues:
I repaired the rotary controller which now works perfectly.
Some preset buttons don’t work or make an odd noise when pushed.
Output is noisy, but usually not noticeable when notes are played.
I will gladly provide audio demos upon request.” Click here to visit listing on eBay

kawai sx-210 “Up for sale is a very rare 6-voice Kawai SX-210 Analog Synthesizer. Functionally and Cosmetically perfect!! Internal battery was replaced years ago and has been regularly maintained. No battery leakage has ever occurred. These don’t come up for sale often, let alone in this type of condition. These keep getting rarer and rarer, because people neglect to fix the battery. As far as editing sounds on the SX210 Ive always found it much easier then on the SX240. Hit a button, then change its parameter with the main data knob. Very fun to program and also has it’s own very unique sound. Awesome for analog strings, pads, and even organs and basses. Truly an underrated classic. ” Click here to visit listing on eBay

sx210 “Rare Kawai SX – 210 Poly Synthesizer. Stored in a smoke free pro studio. The battery was replaced and it was serviced prior to buying it last year. Sounds amazing, very unique compared to the Junos and way more scarce. Move forces the sale. I have had no problems with the synth and have used it on many a tracks, great strings (superb with the Ensemble on) and bass. Everything that I can test works. No scratchy pots, faded voice(s), and all the keys work. The wooden end caps could be replaced, never bothered me. If a tact switch has not been used in a while sometimes it may take two pushes, then it works fine from there on. There is a small chip under a key and a few keys have a little play, but function just fine. Keys are still very much playable and smooth (much better then a pro one or some earlier synths). There is a some scattered wear/marks to the front panel, see pictures.” Click here to visit listing on eBay

“Here’s the problem: Every 8th key or 4th key, depending on setting, and maybe other variations of 4 (6 or 16?-not sure) holds onto to a note, so that the notes rings continuously when it shouldn’t. In other words depending on setting, when you go up in keys or down, you will eventuyally run in to a key that hangs on to sound. But which key depends on what your settings are. Then subsequent keys at the same ratio also are affected. Someone told us this is not normal, no matter how it is set, so it would need servicing for full operation. We do not want to open this up and fix, we also know no other reputable keyboard repair places, maybe you are one. May be it’a a battery or easy fix, and this will rock your world, or it may be a piece of junk, with no easy way to fix even though it’s a cool analog synth. Sorry this is outta our league and we know little about keys” Click here to visit listing on eBay

“Seriously rare analog synthesizer. Super powerful and very unique sounds. This synth works 100%. Professionally checked & the internal battery was also replaced with a new battery (one which will not leak acid on the board). I have owned and come across a lot of synths and this is the first one of these i’ve seen. Only a couple cosmetic issues (see pictures). The front of the side cheeks are a little rough and one of the keys has a little chip out the bottom. Definitely doesn’t effect the sounds or functions. Outside of the battery it’s all original.” Click here to visit listing on eBay

“It came into my shop some months ago, and hasn’t gotten around to be fully repaired, cosmetically it’s brand new looking, all keys clean and soft, all buttons present, and the faceplate is perfect and clear. The person who dropped it off said that he had tried to replace the battery himself, and in doing so, failed. It currently does not power on. While it is currently one of the most beautiful things to have in a room, I don’t have the desire or expertise to replace the battery. I’m leaving it in your hands.

ich versteigere schweren Herzens diesen wohl meistgesuchten Synthesizer in einem Topzustand, in dem er Höchstwahrscheinlich nicht noch einmal so zu bekommen ist.
Ich besitze Ihn seit 1989 und habe lediglich ein wenig damit rumgespielt.1990 habe ich Ihn dann gut Verpackt und auf dem Dachboden verstaut.
Habe Ihn vor ein paar Tagen ausgegraben und angeschlossen.Anfangs reagierten die Parameterknöpfe etwas schwerfällig aber nach kurzer Zeit war alles ok.

“Up for auction is a vintage Kawai SX-210 synthesizer, and a soft shuttle gig case. Believe it or not, I am the original owner! My parents bought this for me in my early teens to keep me interested in piano lessons. It worked. This particular unit was put in my parents basement when I entered the military in 1988, and hasn’t seen any use since then.

I turned it on and all of the memory positions were corrupted. I entered a few patches from the owner’s manual (available here: http://www.kawaius-tsd.com/OM/K_SYNTH/SX210.pdf). and it seemed to work.

First, the issues (that I know of):

Both wood ends are gone. I’ve dome my best to show this in the photo’s
The shuttle gig case foam is shedding like crazy from age. I will ship the sx-210 in the case, but will wrap it first to ensure no foam gets into the synth.
One key only works if you hit the top of the key vs. the bottom (you can see it in the video)
The plastic piece you wrap the power cord is broken
Seems like there is a key randomly pressed when playing with certain programmed patches. May be part of the patch, but I’ve long since forgotten how to program this unit.

Othwerise, my daughters and I had fun dusting it off and playing with it for a few hours.” Auction ended. Click here to browse on eBay.
