Thanks for the firmware versions, guys. Sorry we can't check it Monday -- I forgot that was a holiday.
So it will be Tuesday before we can look at it. I have a good idea what it is, though. We intercept all of the commands so that we can "filter" some out and also respond to some custom commands. The common thread with the problem is that they all require a long button press. My guess is that our "filtering" routine is interfering with the long button presses. But I'm not a programmer, so don't listen to me....
To make up for it, there is some good news triggered by that beautiful photo of the DX-5 playing file from a computer via USB. 192 kHz is finally available (assuming that you even care!). First you have to set the DIP switch on the back of your DX-5 as explained in the manual. Move the first one from "Rsrv A" (up) to "Rsrv B" (down). This will change the DX-5 to Class Two Audio mode, which is required for 192 kHz operation.
(It's required to change this before you install the Windows driver (noted below). But don't be alarmed if the USB audio stops working. Once the DX-5 is operating in Class Two Audio, your computer won't recognize it until it is also capable of Class Two Audio.)
Next you will need to get your computer's operating system (OS) ready. If you have a Mac, then you have to have Snow Leopard (not Leopard). This was the $29 upgrade they released about six months ago. Then you have to install the latest software update via the internet. What you are looking for is OS X version 10.6.4.
If you a Windows guy, they don't care about audio and won't have 192 via USB available for years. So we had a custom USB driver written. It's been tested quite a bit, but not by thousands of users yet so it is slightly experimental. You can download it from:www.ayre.com/Download/ThesyconUSBDVR1.11.0.exe
Make sure that the USB is not connected, run the program, and when it asks for the unit to be plugged in, plug it in then. Wait till it recognizes it in
Windows, then hit OK.
If you don't have any quad-rate files, you can download some free samples from:http://www.2l.no/
