“Up for sale here is a Kurzweil K225 RMX synth/sampler the rackmount version of the famous Kurweil 250. This is a piece of rare synth history right here and it’s in perfect shape with everything working and operable. Not many of these rack modules were made and It’s rare to find one even on Ebay. Display is full and bright, all lights, sliders and buttons working. The housing is all metal and it’s built like a tank. It has the original sound banks loaded in ROM and comes with power cord and manual.” Link

Kurzweil @ 02 May 2017, Comments Off on Kurzweil K2500RS

“I purchased the K2500RS a few months ago but never used it because I very quickly purchased a K2661 for its expanded feature set. For this reason, it is being sold AS IS.

Overall, the unit is in excellent condition for its age, and I believe it to be 100% functional. There is definitely some rack rash on the top / bottom, and a couple minor scratches on the display glass, but the display is very bright and the faceplate is in superb condition. The light scratches on the display glass are not visible when the unit is powered on.

The unit has brand new rack ears and the battery compartment was serviced to remove battery corrosion. Additionally, I will include a bunch of OS and Factory Object disks. The data on the disks is pretty much useless, but the disks can be formatted and reused.” Link

k2v3 ” Here is a Kurzweil k2000 v3 I picked up. I don’t know much about it. Plugged it in both outputs work. Headphone jacks work. Sounds all work. Has the daughter board and the orchestral board. Also looks like the memory is maxed. The chassis is damaged on this keyboard. And I have not checked to see if you can sample on it.the display backlight is out, All the keys work. And it’s pretty clean inside. You can play it as is. Or use it for parts.
Please read: I am done with people that have no feedback. If you have below 10 feedback score do not bid!” Link

Kurzweil @ 30 August 2016, Comments Off on Kurzweil K2000

k2 ” This is a Kurzweil K2000 with pretty much every option that is available for this model. It has a built-in SCSI hard drive with cooling kit with all available Kurzweil factory sound banks installed and the maximum amount of memory that can be installed. The display has an EL backlight kit to make the display much more readable in low light. The floppy drive worked the last time I used it but I haven’t used it for a long time (using MIDI transfers from the computer is easier anyway).

There are a few small lines in the LCD display but it doesn’t make it unreadable and is probably fixable if you have the patience. There are (free) computer display emulators that are easier to use anyway so to me it wasn’t an issue. There is some slight wear from use but the side that matters is almost like new and all the labeling is clear and readable as it was new.

The keyboard is velocity sensitive with aftertouch and the pitch and modulation wheels work well. It also has two sliders that can be assigned to various parameters depending on the sound patch.

Everything works, all outputs are clean and distortion free, the 10 GB hard drive works very well. I will leave whatever patches are on it now.

This has been a fantastic keyboard and is still one of my favorites.” Link

Up for auction is my beloved Kurzweil K2000R. This is an amazing synth with endless possibilities. I’m selling it with the rack ears and both manuals. It has the added Orchestral ROM but it does not have the sampling option. I bought this from the original owner a few years ago who only used it in his home studio. I immediately racked it and its been in my studio ever since. This synth is very clean and working great (I’ve never had the need to use the floppy drive so I haven’t tested it). I used the synth up until about 2 weeks ago, so I know its working great.” Link

This one is really beat up.

It was painted by someone and then someone tried removing the paint with acetone.

I was hired to take the guts from one K2000 and turn it into one nice working synth.

This is the leftovers.

There are parts missing and it’s not working.

It’s in rough shape.

k2000r “This auction is for a Kurzweil K2000R Player, the rack mount version. There is no sampling option in this unit. It has a 3.54J setup version and comes equipped with the daughterboard used to connect the ROM upgrades and the Orchestral ROM upgrade itself. It has 4MB of sample memory. You can see this in the picture that shows the disk screen. I have checked this out thoroughly and it plays and sounds great. However, being an older unit, it is being sold as-is so bid accordingly. The only warranty is that it will not be DOA. I am including the K2000 Musician’s Guide and also the Supplement which has info about the Version 3 software and the Orchestral ROM. Both of these are must haves to get the most out of this unit. Also included is the K2000 Factory Programs & Demos disk and the K2000 Orchestral ROM GM Sound set disk which has 130 or so additional sounds which I have already loaded into the K2000. ” Link

Kurzweil @ 01 September 2015, Comments Off on Kurzweil K2000

Got this from a friend a couple years ago and have never used it. Unit powers on and I can hear sounds through headphones, however I’m not savvy when it comes to sampler keyboards, so I haven’t tested it really beyond that. More comfortable playing my Casio I’ve had since 1983.

Cosmetically this is in great shape, some scratches on the bottom and tape residue on the top. I tried to clean that off, but didn’t want to harm anything by using cleaning products, so it didn’t really come off (i’ll leave that for the buyer to take care of – assuming you know what you’re doing better than I)

Keyboard comes with nice travel case, soft but sturdy, original power supply and a foot petal (not sure of that state of that, but it’s my understanding that replacing those is fairly cheep)” Link

k2kr ” This is a Kurzweil K2000R rack mounted synthesiser utilising Kurzweil’s VAST operating system. I am selling some items that I have had for a while due to downsizing. I have had this item and a K2000RS in my rack for sometime and used them widely. In my view the piano sounds from this unit are the equal of any. This unit is extremely versatile and programmable but most importantly is capable of great sounds from the piano through orchestral to wind and brass. It fits in a standard 19in rack and with an appropriate MIDI controller will give great service.” Link

150” I got this in a lot of guitar stuff. I’m not really a keyboardist so I wasn’t able to fully test this thing. I tested this with a midi keyboard and it played fine, let me change sounds. All the presets sounded pretty good. The volume pot was a little dirty but I imagine just using it would clean it up. The power button is sticky, kinda like something was spilled on it, which makes the button stick a little.I just wiggled it and it popped back out. Nothing a simple clean up couldn’t fix or just some usage. I was unable to test the cassette part as I don’t have a cassette player or the cassette. That is the extent of my testing. I don’t know how to program this so I was unable to test those functions. There is a small dent on the top, see pics for cosmetic damage. Because this is old and I can’t fully test this, consider this sold as is, no returns. ” Link

k2000ks “I am selling a Kurzweil K2000 synth. It is a great synthesizer but needs a little work done. It comes with a floppy disk of 200 preset sounds which are incredible. I am by no means a synth expert but the main problems I noticed with the synth were: the contact needs to be cleaned on the lower c# key the first c key has a bit of resistance ( I imagine this is an easy fix), the keyboard powers on and emits a blue light but I have had a bit of trouble accessing the sounds (this could be because I have know idea of what I am doing). The keyboard was functioning great a month ago so it may not be too difficult to fix for those who know what there doing. Cosmetically the synth is in decent shape. I’m sure if you fixed this thing up, you could get a ton of extra time and energy out of it. Also, after having it looked at by a buddy who knows vintage synths well, apparently the keys themselves are awesome and rare – allegedly potentially valuable. ” Link
