I have a Yamaha DGX220 Piano Keyboard Does anyone of you out there experience the same problem?

Have you installed the latest driver and did you install it while the keyboard IS NOT connected to the Mac?

After installing the new driver, have you restated your Mac, let it boot up, then try plugging in the keyboard's USB connection?

To answer your question...yes.

I am running OS X Mavericks but only 10.9.2.

I am having no issues with Mavericks with any of my current, existing variety of connected hardware.

I record the midi sequence from a remote MIDI sequencer and the audio from my entire keyboard setup goes directly into a audio interface box into either GarageBand, Logic Express OR Audacity. I don't use USB directly into my Mac.

So my keyboard audio and MIDI setup is different from what you are trying to do.

The way my keyboard setup is it doesn't lock me into issues with new OS X versions problems as I am always just recording digital audio directly into my Mac and nothing else.

What is the Yamaha USB driver for, anyways?

To connect up to a supplied MIDI software sequencer on the Mac?

It is not important to your situation at the moment.

Again, I ask what is this USB driver for your keyboard for?

What are you trying to accomplish with this keyboard by plugging directly into your Mac?

What Mac are you using? How is this keyboard connected to your Mac? USB or Audio input?

I already looked up your Yamaha keyboard model and this is an old 2006 run of the mill electronic keyboard.

I have a similar Yamaha model I use, by itself with my Mac when I do not feel like powering up and using my entire keyboard setup.

I use only the audio input on my iMac OR through a FireWire digital audio interface box.

I do not use the USB connection unless I am using any MIDI related functions.

You are not supplying me with enough info to give you any useful advice.

Hi,

Would you explain what remote MIDI sequencer is?

Your keyboard has a bulit-in Music recording device. This is actually a buiti-in digital MIDI music sequencer. It can also, output through the MIDI connectors the MIDI sequence to either software on a computer or other external MIDI devices like dedicated sound modules or computer software sound modules or software sequencers

I use both software MIDI music software sequencers and a dedicated hardware MIDI music recording sequencer in my system.

Dedicated digital MIDI hardwaremusic sequencers do the same things as the bulit-in sequencer on your keyboard and computer software music recording sequencing.

Digital MIDI music sequencers DO NOT RECORD SOUNDS.

They record things like what keys are pressed on the musical keyboard, how much key sensitivity and pressure was applied, other parameters like if you change the pitch of the keyboard up and down by half steps, the sound number and sound bank number, records pedal information, records wheel and pitch bend wheel information, records other MIDI active button controller information, etc.

Basically, keyboard sequencers, hardware sequencers and software sequencers record the performance nuances of your playing and NOT the actual sounds that you are hearing.

Are you using this keyboard with GarageBand?

Why is this music keyboard being used with your Mac?

You are just not giving me any good info to be able to help you.

There are ways to use this keyboard with your Mac and get the keyboard audio into your Mac that shouldn't have any bearing on what OS X operating system you are using.
