Looking for a used ROLAND or KORG keyboard, 7-Octave

The analog cx3 uses old school organ technology where a single oscillator for each scale note is divided to put it in the correct octave. Its likley the c# oscillator needs to be replaced. This is a job for a tech rather than being user serviceable.

Take it in for repair. There may be a broken line for the velocity sensing of that octave of keys that is causing the velocity to be sensed low. The repair is NOT DIY if this is the case.

Read page 135 regarding the note range settings. Look also for keyboard split information. You may have the keyboard set to NOT play notes in the top octaves for the particular voice you are using.

Just consult that problem. to the costomer support personel to fix your problem

Sorry I didn't find you 'til now. I just got the same problem.
If you haven't found out already, Roland has them available from the support dept. (323-890-3740) at $9.00 a piece or $200 for a full set of 88.
They say they've re-designed them to be more durable.

Try wdgreenhill.com for the parts. They are in England but give great service and specialize in hard to find parts.

This may be too late, but,

I was successful installing a Casio Privia PX-575R USB midi keyboard to Windows 7 Ultimate x64!!!
I tried to use Yamaha, Korg, M-Audio, and some other drivers I don't remember and
they did not work.

I then downloaded the win 7 x64 driver for PC-50 from
http://www.roland.com/products/en/_support/dld.cfm?PRODUCT=PC-50&iRcId=16224976&dsp=1
(but I bet any of them would work) from Roland. All I did was change the hardware ID
in the INF file under

[Roland.NTamd64.6.1]
;; Windows7
%RDID0053DeviceDesc%=RDID0053Install, USB\VID_07CF&PID_6802

The ID is after the comma and the one you see above is from the Casio keyboard i have. The
hardware ID for your keyboard can be found in "device manager". Just choose your
hardware/keyboard and go to "details" and choose "hardware id" from the drop down
menu and put that after the comma. It will start with "USB" since it is a usb
devise. There may be more than one ID but the first one works for me. Then just do
a manual install by right clicking "computer" or "my computer" and click "device
manager" tab. Then find your keyboard (probably a yellow exclamation mark next to
it) and double click it. Then go to the "driver" tab and click "update driver".
Then choose "Browse my Computer for driver software", then "Let me pick from a list
of device drivers on my computer", then "Have Disk..." and browse for the INF file
you just put the hardware ID in and click "open".

You now have a working Casio keyboard for a 64 bit or x64 windows 7 operating system.
You can do the same with Vista x64 or XP x64, just download those drivers and edit the hardware ID the same way.

Thanks
