” Up for auction is this well-loved Casio CZ-101 synthesizer. It’s in great working condition! As far as my programming skills go, everything seems to work and I’ve had no issues. As you can see in the photos, it had duct tape on it in a bunch of places and there are some scratches but not on the LCD screen and not in any way that makes the functions hard to read…well, at least no harder than the small font size! As I’ve noted above, the headphone jack is a bit noisy, but the main line out is perfect as are the pitch bend wheel and volume fader. It doesn’t come with a power supply (as it didn’t when I got it) but I’ve been using a regular 9v adapter with no issues…I’ve never tried using batteries to power the synth. ” Link

“Up for auction is a Casio CZ-101 Phase Distortion synthesizer from the mid – 1980s. Its in great condition, although it can only be powered by batteries. I attempted to power it by a 9V adapter, but it was sporadic and I had a hard time getting the unit to power on from it. Maybe it needs a new jack, but I don’t do electronic repairs. With “D” batteries the synth powers on and plays.” Link

” Casio CZ-101 is a nice litlle 80s digital synthetizer
This little synth is a real surprise. It sounds nothing like a DX7 as some have suggested. It is more analogue in its design and structure and is capable of much warmth from its DCOs.The build is fantastic. You can develop sounds using conventional parameters. The number of editing parameters is surprisingly comprehensive. is battery powered..like the wasp and cs-01. It is a really useful keyboard..great for people short of space and working on a budget.
In semi-working condition, when you turn it on it says write to memory and stays on just one preset., but there is sound, and all keys do trigger so it can be used as a MIDI controller.
also missing one key, and the volume slider cap., some scratches, also missing it’s battery compartment door.

“Here is a chance to buy the unique sound of the Casio CZ-101 phase distortion synth. Don’t be fooled by the look or by the fact that it’s made by Casio – this thing is capable of making some truly unique and weird sounds!
This is a pretty old synth and as such is has a number of scratches and what look like burns in the plastic cover / keyboard. It also has a slightly loose power connector which means if you knock the power lead a certain way th synth will reboot. Whilst not ideal, it can certainly still be used but it probably very easy to fix anyway if you handy with a soldering iron (I’m not!).
This comes complete with a memory cartridge (for storing sounds) and with the original manual.” Auction ended. Click here to browse on eBay.

“This one-of-a-kind keyboard is in great condition. It works and has been fully tested (and played). There are no bad keys. You’ll just need to use a DC 9V adapter or batteries for power. While I tested it with a DC adapter I did not have enough batteries on hand to test the battery functionality (takes 6 D size). I have no reason to believe that it does not work. The battery door is intact. I have taken pictures with it plugged in so you can see it powered up (power adapter is not included). There is some wear on the bottom of the unit, mostly scuffs to the paint or coating with a few scratches. The keyboard has a knob on each side that you can use for a shoulder strap (if playing as a keytar). I have not tested the memory card functionality because I don’t own a memory card. However, I was able to modify and save internal patches easily.” Auction ended. Click here to browse on eBay.

‘A classic. I’m not a keyboard player so this synthesizer basically spent its entire life in my closet. (I’m the original owner. I’d purchased it new from a store in Hollywood.) I’d describe it as in New Old Stock condition (NOS in Fender speak); basically mint. I’d even gotten the RAM and programmable cartridges (both the RA-6 and the RA-3 are included in the deal).

“”In good cosmetic condition and in 100% functioning condition”
Includes two memory cartridges (1 Casio the other an EZ-CZ cart.) and an Archer PSU.
Please see pix as to unit’s condition.
Everything works as it should and sounds great too !!!
I mainly used it for bass tracks… really has great bass presence in a track.
It also has an eight stage envelope generator, great for pads that swell.
The Casio M-cartridge is great… the EZ-CZ has four memory banks,
but every time you change the two AAA batteries you loose your patches…
though this shouldn’t be a problem if your using a universal librarian.
This little synth is most definitely not a toy… but a killer little synth classic.” Auction ended. Click here to browse on eBay.

“Here’s a nice CZ-101 in pretty good shape considering it’s age. All buttons and keys work. There are only three areas that need to be pointed out.
First – the headphone output is noisy intermittently. It wasn’t a big deal to me because a twist of the headphone plug would usually knock the noise level down. The line output is not noisy at all. I cranked it up recently and it sounded pretty clean.
Second – there is some corrosion in the battery compartment. There is no evidence of batteries leaking in the battery compartment or anywhere internally so I just chalk this up to old age. It does have the original battery door.
Thirdly – the line select 1+1′ light does not always come on when cycling through the line select configurations. It does not effect the sound in any way and a gentle tap on the light will usually cause it to light up. I didn’t think it was worth fixing.
Otherwise it has some scratches and rub marks but nothing that effects the sound. Also included is a very rare EZ-CZ RAM cartridge. This stores four banks of 16 sounds for a total of 64 sounds available in addition to the internal 32 sounds. The sounds that came with it are long gone but I have replaced the battery (typical 3 volt button battery) so it should be good for another 10 years or so. I will also include a third party power supply of the correct voltage and amperage for this synth.
If you’ve bothered to read this far you know what this classic mini-synth is all about. On it’s own or layered with another synth it has always had a place in my studio. I’m only selling it because I am funding other purchases and I have another CZ hanging around here somewhere.” Auction ended. Click here to browse on eBay.
“This is the original Casio CZ 101 in steller shape.I purchased it in 1985. Many musicians seek these keyboards for it’s nostalgic sound.
