Yamaha DGX 640 - Midi controller??

by Jose

Good Morning,

My question is if the Yamaha DGX 640, via its USB to Host connector, works as a midi controller compatible with music and audio software as Pro Tools, Logic, Reason??

I've been interested on buying it.

Thanks in advance,

It behooves me why Yamaha did not make these keyboards with MIDI in/out ports. Why should we have to go through all this??
I have a DGX 505 and tried all the camera kit adapters, etc and could not get it to work, either. Then i have a cheaper Yamaha that has the midi ports and have had no problems connecting it to an instrument at church. Unfortunately I'm not getting the better quality sounds i would have from the 505. Im very frustrated and disappointed by this.

Difficulty using it as MIDI Controller
by: C@£$@R.

Hello there
Please give me a step by step detailed information on how to use my Portable Grand DX 640 as a MIDI Controller on Reason and Cubase.
After downloading the yamaha MIDI driver and then connecting via USB/MIDI cable, nothing seem to work. My PC didn't recognise the input and downloading the driver was initially a success (saying that my processor wasn't adequate enough).
So help me with this information as soon as possible.
Thanks for your cooperation.

USB device not supported
by: Anders

I also get this message when I connect DGX640 to the iPad through the camera interface: "The connected USB device is not supported".

Since a special Yamaha driver is needed when you connect DGX640 to Windows, I assume that Yamaha has not bothered to use the generic USB MIDI driver that all devices would know about.

But apparently someone got it working, according to the previous comments. If you have any hints on what you did, it would be appreciated! Thanks

Specific settings?
by: Anonymous

I too have a Yamaha DGX-640 keyboard. I have the iPad 2, camera connection kit, and the USB cable to connect. When I plug my keyboard into the iPad it says "The connected USB device is not supported". Are there specific settings I should check to fix this?

iPad Camera Connector Kit
by: Anonymous


I found a way to interface this- You just need to get the iPad camera connector kit which retails for about $30 and you will be able to hook USB to your iPad as well as have a slot for SD memory card. I have been able to successfully use my iPad and Yamaha SDGX640 with this.

It works as MIDI device. Only one thing you need for it is the Yahama MIDI driver, which is included in CD.
