“The K4r was one of my favorite synthesizers in the 90’s. It has a resonant filter, so unlike many of the ROMplers from back then, this synthesizer can make some really cool and aggressive sounds. It can sound a lot like a D50 because of the ability to layer 4 different waveforms, but it is a LOT easier to edit from the front panel, so I tended to use it a lot more. The Basses, Organs, synth pads and percussion samples were all over my trip hop tracks back in the day. In fact, I got the idea to buy this when I saw it in the Sneaker Pimps studio. These days I see Legowelt has one, and though many prefer the K1 because of it’s lower bit rate and use by some of the old warp artists, the filter on the K4 makes it a way better synthesizer all around.” Click here to search for synths on eBay

“This is a vintage Kawai K3 Hybrid analog digital synthesizer. The issue is when a patch is selected some of the notes do not play. When a different patch is selected different notes do not play and the others that were not playing do. I did a factory reset on the unit and it did nothing to resolve the issue. ”

“Up for sale is a Kawai K1m desktop synth module for PARTS or REPAIR. It powers up and plays and all knobs and buttons function but every 6th or 8th note played yields another sound or the sound played is distorted. Maybe someone out there with more knowledge or time can repair it or use it for parts to repair another unit. “
“Virtually MINT condition. Sounds phenomenal as you would expect if you know this synth, all functions fully operable. Display screen sometimes fades when on for a while, or goes blank. Off / On solves the problem. Screen should be replaced, or the failing component for 100% operational reliability. Multiple additional patch discs included.”

” Synth is in good cosmetic and functional shape with some light wear and tear (see pics for details). We tried to test to the best of our knowledge, but understand that we are not a musical instrument shop, so there might be some work to be completed to it to make it fully operational. Powers on and plays through the headphone jack. ” 
” This unit is like new and sounds great. Bought new by someone who wanted to learn to play keyboards and got lazy. Hardly ever played.” 
“I purchased this new in the early 90s. Time to let it go. I recently spent about 10+ hours of time with this unit transfering old song parts to the computer, consequently I know it’s working just fine. It’s in excellent condition. There is a security plate attached to the bottom of the unit that I used to secure the keyboard at a live gig. I’ve also etched out (removed) my name and ID number that I engraved on the bottom of the unit. Original AC Adapter included along with the original manuals. Happy bidding.”

“This auction is for a Vintage Kawai K1 61 Key Digital Synthesizer Keyboard. I have had this unit for a couple of years but didn’t use it very often. Everything worked as it should and sounded great. I pulled it out a couple of weeks ago and for some reason it lost all the sounds in it’s song back. No matter what bank you pick the sound remains the same so it only has one sound and it does change pitch with each key. I have looked online and found that the sounds can be reinstalled and with a quick search on ebay I found sellers selling CD’s with all the original sounds and some people even had modified sounds. The originals were $6 to $9. I just don’t have the time to mess around with it and reload everything. “
“This Item is in fair condition with a few scratches on top.
“This is a Kawai K1 Digital Synthesizer. The Keyboard is in good condition and it is mostly functional. However there are 4 keys whose contacts might need some attention because they don’t always fire off with a light touch. Specifically they are the A#, D#, B, and E of the middle section. Power supply included. ”

LCD bulb in the display needs to be replaced, but does not affect functionality at all, display can still be read, just no backlight. Original synth from the 80’s. Manual print out and power cable included. No reserve, thanks for looking. ”

The top cover is loose and not connected to the bottom. I do not guarantee this item. Could be used for parts or could be a great deal. ”

I tested the synthesizer to the best of my ability, but I am not familiar with its full functions. Being sold as is. 32K RAM Card included, but it does not seem to be working. Power cord included.” 
“Great Condition Kawai K1m desktop synth with super cool string and bell sounds. Additive synthesis, and the best feature, a joystick that allows you to mix between 4 parts (sounds) great way to achieve some very interesting sonic effects.
” Please note that there are two broken keys (The 3rd D Key, The 5th A Key). The A is glued together. While the D is simply missing that bottom part as pictured. The keys still function fine when pressed, but will need to be replaced. “
” Vintage Kawai K4 Digital 16bit Synth from the late 80’s.
“Late 1980’s digital synth. I made a few cool old school techno/rave saw leads with it, but it’s good for other music styles also, like Industrial or 80’s new wave. The dark electro-industrial band Clock DVA used one during their peak time in the early 1990’s.
“One vintage Kawai K3 Analog / Digital Hybrid Synthesizer fully tested. Pitch blend needs repair, all other functions and keys are properly working. Cosmetically this vintage synth is in good and clean condition. There has been some wear to the plastic covering the program options on synth.”
