CMS Discreet Synthesizers Module 1004 Pearlman Oscillator

” I am selling my CMS ARP 2500 clone module of the 1004 Pearlman Oscillator. Alan Pearlman designed the 1004 in 1969. This is a high quality reproduction by CMS.

High quality construction and top shelf components, Switchcraft jacks, Alps attenuators.

CMS engineering used in many professional studios in the USA and Europe.

Main frequency control pot features an extra large geometry “virtual infinite resolution” potentiometer for accurate control of frequency.

Integrated T-Mixer section has also been accurately reproduced to facilitate unusual waveforms.

3 control voltage inputs. 1 fixed at 1v per octave and 2 more with attenuators.

1 Pulse Width Modulation input with attenuator.

Easy to understand flowchart front panel graphics facilitate operation.

The brushed aluminum front panel is made of a special material that has the image impregnated into the aluminum surface. It will not fade over time or wear off from finger action.

This is the first version of the 1004 made by CMS. It has been used sparingly inside a studio and mostly kept in its box. It sells on the CMS site for $729.00 but I am pricing it to move. ” Click here to visit listing on eBay

Kurzweil K2000

“This is a Kurzweil K2000 synthesizer that works perfectly, just the floppy drive doesn’t work ,it just hums as you can hear it turning, trying to load or save data but cause it’s old its done. So that can be replaced with one of the usb to floppy disk replacement parts sold here on eba., Can’t do it myself as there are no specilists here on the island of Rhodes, Greece, plus, i have Multiple Sclerosis that made me liquidate all my studio, so it needs some attention, if you need the floppy, i need to list it as not working allthough it loads and saves and works with all SCSI drives otherwise. It needs some care i agree thats why i am selling it below market .” Click here to visit listing on eBay

Kurzweil K2000S

“All functions on this keyboard work well. Pitch/bend wheel and the mod wheel work great. All dials and buttons work great. All of the 61 white/black keys respond perfectly when pressed. A few of the buttons sometimes you have to press them a 2nd time, but it’s not very often. It’s rare to find one of these K2000S’s in full working condition like this one. One of the white keys (an E note – see photos) is slightly raised 1/8″ but it plays fine and a Kurzweil tech could level it back into proper position. A few screws on bottom missing. Some scratching here and there on the case exterior (but not much and it’s mostly on the bottom) and very, very slight yellowing of the keys but that’s normal stuff to be expecting from a synthesizer of this age. Unit is very cosmetically clean. Please see description for all the great upgrades I’ve put into this thing. Unit comes from a clean & non-smoking studio environment with no kids or pets around.

It’s rare to find one of these K2000s in full working condition like this one. Some of the protective felt hairs at the back end of the keys are kind of pushed into the casing, but again, doesn’t affect the operation of the unit at all and a Kurzweil tech could push them back out.

Kurzweil 1000 SX

“This string expander module has some great string sounds, especially the low bass section and the high strings. Some of the solo sounds are just average. I’m the original owner. I used it extensively in the late 80’s through 2004 on numerous commericals and multi-media projects. I left the biz in late 2004, and it’s been mounted in a rack in my smoke-free, personal use studio since then. It’s mostly been left powered off. I don’t recall if the display ever had a backight, I don’t believe it did. However, if it did, it certainly doesn’t any more. The display is readable in a well lit room from the right angles. I’ve tested it, and it’s working great and still sounds great. It includes the original manual, which in itself is quite a novelty. I’m selling it because I’m unlikely to write music any more, and it’s time for this module to find a new home where it can be put to good use.” Click here to visit listing on eBay

Kurzweil K250


This Kurzweil K250 is in Very good condition for the age. Only cosmetic wear is one caps missing on the “3” slider. Currently C key is lazy but fully works. however I have a part to have that fixed by the time this sells. Includes the power supply which also works as a sustainer pedal for the keyboard itself.

This is the Last of the Fully Weighted with “real” Piano Hammer action Keyboards/Samplers

This is a loaded K250 and has too many extras to list, some of which I have no idea what they are. Can send pictures on request.

Comes with 12 RAM cartridges which are impossible to find and almost worth the price of the keyboard.

I will also include these hard to find manuals that were from Patrick Moraz’s K250. I owned his for many years ago during the time I worked with him in the 90’s.

Manuals:
* How to play the Kurzweil K250
