SOURCE: certain keys do not make a sound..

The wire from pin 1 or 7 of CN1 on the GHL88L (left end) circuit board is open where it goes to the middle circuit board. This could be a bad cable, improperly seated cable connector, or a crack in the circuit board(s) connecting to these wires. These are the common matrix wires associated with only the C# and G keys for the left 1/3 of the keys. If more than 1/3 is dead, then the problem is likely on the middle board GHL88M that connects to the mating cable to the CN1 connector.

There are two wires dedicated to the keys for the two contacts that are used to measure velocity of the key strokes. There is a mechanical position between closing the contacts and the time is measured by the processor as velocity.

If you are the least bit worried about working on electronics you best have a service person do the repair. The keyboard has to be lifted out after removing the top and disconnecting other cables.

SOURCE: as i play notes on

Check if you MIGHT be in a "guide" or learning mode. Some Yamaha synths have a mode that will play and then wait for you to hit the right key before moving on. If this is not the problem, a fix is not DIY and will require repair. I assume you are NOT using MIDI as in that case it is called "dreaded MIDI drone" and is due to data looping back into the unit which is an external fault.

Where can I get a manual for portable grand D6X640 Yamaha piano


Do you mean the DGX-640? To my knowledge, Yamaha doesn't have a D6X line of keyboards. Most of Yamaha's manuals are available from their support page: http://download.yamaha.com/top/?site=usa.yamaha.com&language=en . The DGX-640 support page is http://download.yamaha.com/search/product/?language=en&site=usa.yamaha.com&category_id=16084&product_id=1056822 . Scroll down to find the owner's manual in various languages and other documents. Yamaha provides javascript links to the manuals on the site; these do not resolve to specific direct links in my browser history.

I hope this helps.

How do I download files from my yamaha portable grand DGX-230 to my computer


To download/transfer files to computer, you need 2 softwares from yamaha website. USB MIDI drivers and MUSICSOFT DOWNLOADER.
Install drivers first,and then Musicsoft Downloader.
Connect keyboard to PC/notebook by USB cable.
Run Musicsoft Downloader.
If you click "Electronic Musical Instrument" in the Musicsoft Downloader display.and then "System Drive", a file named "08PG76BUP" will appear in the lower right corner of the Musicsoft Downloader display. This is the backup file that will transfer to computer.
Usually yamaha came with CD-ROM that contain divers and softwares + user manual,so you don't need to download.
I hope this helps.
Regards.

How do i reset the keyboard to factory settings? It sounds really weird right now


You can normally reset Yamaha keyboards by holding down the highest note while turning on. If you want to do a full factory reset see below - remember this may delete all songs etc you have saved to the keyboard memory.

I have a new DGX. My problem is when I want to add a dual voice to the piano. I press the portable grand button then hold the dual button till the violin voice appears then select the voice I want and...


HI, Let me answer the question.

1) Select the DUAL VOICE (not portable grand ) button and hold for longer than 1 second.

The choose voices required.

If you press the Portable Grand button this resets the keyboard top a piano.

I hope this helps

Where can i find windows 7 x 64 drivers please help mee !!!


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.
