“Up for auction is a Yamaha CX5M “Music Computer.” I bought this from a friend who worked in a music surplus factory for a chain music store. He got the one with the music stuff…..all I got was this lousy Word Processor!

But seriously, it’s the same computer – this particular one just comes with the “word processing” card (which I imagine absolutely no one would have any use for today). But I also imagine that if you need this thing for parts or if you have some other stuff but need this unit, it might be worth your while. Maybe you can circuit bend it or something.

Either way: THIS UNIT IS BEING SOLD AS IS. I have no way to test the musical aspects of this device.

COMES WITH:

–Manual
–Cord (attached)
–Word Processor cartridge

DOES NOT COME WITH:

–MIDI cables
–Other cartridges
–Anything else” Click here to visit listing on eBay

” this CX-5MU was a project of mine. when I found the Synth it did not have the any of it other parts so I had to find a way to use it. first I made a normal MIDI cable in to a adaptor for video so I can see the MSX interface on my TV. then I needed a way to get it to play sound so I took apart the FM Synthesizer Unit and soldered a small switch on the side just above the Music Keyboard port so that if in the future I got the Keyboard it could be plugged in. I have uploaded all the pics I could to show what I have done. I hope its not to much or just enough to make it easy to use. ” Click here to visit listing on eBay

“YAMAHA CX5M COMPUTER/Sequencer/synth with Power Supply

plus KEYBOARD

comes with manual for YRM-101 “FM Music Composer” program cartridge

and Yamaha MSX ‘parts list’

Don’t know a lot about these as I never got round to using it myself. With the programing cartridge, you can run a sequencing programming and even an editing program for the synth module plugged in under the unit. This unit has MIDI in/out and audio L/R out as well as the keyboard connector.

As you can see in the picture, the no ‘2’ key is missing. These keys ‘click in’ so the keyboard is not actually broken, it’s just the key that’s come out and been lost. I used the blunt end of a pencil to verify that you can get no.’2′.

I’ve powered up the computer using the composite video output and it seems to work ok, though you will need the program cartridge (YRM-101 – which sadly I don’t have) to run the sequencer and on board synth. These program cartridges are available on eBay and included is the user manual for the program cartridge; the manual is in good condition though some pages have come loose from their binding.

As I do not have a program cartridge, I am unable to test this properly so please note that I cannot guarantee this is fully working. Otherwise, the items are in quite good condition. The keyboard has a couple of knocks and marks on the wood ends but nothing major.” Click here to visit listing on eBay

” I am the original owner of this Yamaha CX5M music computer system. It has almost every available peripheral option. I did some work for my brother-in-law who owned Penguin Music Store and this was part of our barter deal. I only set it up and fiddled around with it for a very short time and it has been packed away in a smoke free home ever since. Many of the components have never been out of the box.

I really don’t remember how to set it up and work it. When I laid everything out to take photos, I did power up the components and they all come on. I did not hook anything up to try it out though. As I said many of the components / programs have never been out of the packaging. It appears that I have all of the manuals for the system itself as well as the manuals that came with all of the software. ” Click here to visit listing on eBay

“Here is a rare Yamaha CX5m MK II music computer with full size keyboard.

This version of the CX5m contains the fm synth that allows midi to be received so you can connect this to your synths midi out or computers midi out and it will drive this synth(The first version of the cx5m and some CX5m II’s utlised a slighty different version of the fm synth and it did not have the midi in capability so it was a welcome update.Rest assured this CX5m II has the synth with the midi in capability.The CX5m MK II also has the better internal power supply so it just plugs into the wall without a bulky power supply of the mark 1 version.

The sounds you can get from this are really good and can be used from anything from Boards of Canada type weirdness and drones to tight house basses to Rhodes pianos, lovely evolving strings and digital textures.

Lots of the software associated with the cx5m comes on carts-This has two cartridge slots available.

This has lots of software already in ROM and a simple command brings up a graphical user interface to allow easy programming of the synthesiser.

If FM synthesis has ever scared you then just use a CX5m graphical user interface to program with ease. It is all graphical and layed out in front of you-Nothing could be simpler.

All in all it is a great bit of kit and they are getting more sought after, especially the MK II version.

This one is in great condition and works perfectly. The keyboard also has a nice action to it and connects via it’s own special lead(supplied) to a port on the side of the computer leaving the midi in and out free for other uses.

If you have always wanted a CX5m then this is the one to get-MKII version and is in like new condition.” Click here to visit listing on eBay

“Everything is here except a monitor (which did not come with original purchase anyway). Been stored in plastic in cool dry place since mid 80s when it was purchased new. As far as my knowledge of these instruments it’s working great. Took good care of it. Plugged it in after 20+ years and tried the voicing program (keyboard sounds) and all keys work and voices work. Bought it for help in programming a Yamaha DX7 but never used it for that. Used simply as a performing synthesizer. All manuals come with. So, what this auction includes:

1) Yamaha CX5M computer (located within the qwerty keyboard unit).

2) Yamaha YK-10 musical keyboard (plugs into the puter)

3) Yamaha RF-02 modulator (for plugging into monitor, *note* I did not use this and have not checked it.

4) Three (3) programs: voicing program (sounds), DX7 voicing program, composer program (never used).

5) All manuals (5)” Click here to visit listing on eBay
