Windows 7 Verifying Yamaha USB MIDI Driver Installation and Connectivity https://www.yamahamusicsoft.com/help

PX 410r uses IDES 4.0 downloadable from
http://www.casio-europe.com/euro/emi/specials/ides/downloads/
and not another version.

I suggest you uninstall the Casio USB driver from Control Panel'system'device manager then Reboot the PC without the USB cable.
Download latest USB driver from :-
http://support.casio.com/en/support/download.php?cid=008&pid=20
64 or 32 bits versions are both available.
Load driver first. Plug in the usb cable only when software tells you to do so.
Uninstall Data manager if wrong version.
Install IDES 4.0

Your Yamaha DGX 203 Portable Keyboard - USB-MIDI Driver Version 1.2.2 ie. for OS Win9x/ME.

Yahama site does not have the Win7(x64) Drivers ie. USB-MIDI for your Keyboard Model DGX-203

But you can try the USB-MIDI Driver Version 3.1.0 for Windows(R) 7/Vista/XP 64bit for Model DGX-520 @ http://usa.yamaha.com/products/musical-instruments/keyboards/digitalkeyboards/dgx_series/dgx-520/?mode=model

I can't assured you that it will works on your system. Since your Keyboard is no longer in production, I doubt Yahama will provide you with the official USB-MIDI drivers for your Keyboard even you requested for it.

I guess this is an option you can try and hope it works & good luck.

Regards.

You can connect it with USB connection to your computer. It should be plug and play, but some drivers might be required.
You can connect it also via MIDI interface: - you will need sound-card with MIDI input connector, or you can use special MIDI device like M-Audio UNO.

Sometimes just plugging into a different USB port on the back of the laptop will work better than the ones on the sides. I also find using the headphone jack out to a couple RCA mixer channels is far more reliable that USB which often comes and goes. Just a thought. Beringher should have the drivers, you can download and install the universal ASIO drivers as well which can be a little tricky but works for recording - from here: http://www.asio4all.de/

Yes, the charging is done via the 5 volts supplied on the USB cable.

That will bring up the diagram!

Hello,

You need a midi to usb interface, otherwise it is quite simple. I personally have an M-Audio interface that plugs into my midi out and plugs into your usb port on your computer. Once done, you can create a profile in Reason for your CTK. Windows 7 will notice the M-Audio device and then you will be able to use midi. You may have to install a specific driver for the particular M-AUdio device (or another midi to usb interface) but that is simple. You do not have to worry about a driver for the keyboard.

In my experience, M-Audio makes about the best midi/usb interface, and they come in all popular configurations. I use a very small 1-to-1 interface, though there are multi port interfaces one can buy. I purchased mine on eBay, though you can find them at Guitar Center if you have one in your City, or alternately Musiciansfriend.com web site. Many online stores sell them though. You amy want to use Amazon or a price comparison web site to find your best deal.

Thank you for using FixYa, and good luck.

Hi I had exactly the same problem with my Macintosh, it worked fine until recently but suddenly stopped working. As a matter of fact it is probably due to a compatibility issue of the USB driver after a recent software update of MacOSX drivers. Fortunately I have an old Macbook pro with an old version of MacOSX and the Tascam showed up immediatly and USB worked fine. Therefore, if ou can downgrade your USB driver it might solve the problem.

Try this driver.
