Is my EDIROL product compatible with the Microsoft Windows Vista(TM)?

Can I connect the listed products to the USB 2.0 compatible port and use them?

When recording audio from a turntable into my Edirol Audio Interface, the signal is very low. Why is this?

I installed the driver in my Macintosh, but an error massage saying "Unable to use the function extension” appeared.

Can synchronization messages such as MIDI Clock or MTC be passed through a MIDI interface (or the MIDI interface built into a product) made by Roland/Edirol?

In Macintosh OS 9, how can I see that my MIDI device is working correctly?

What does Direct Monitoring do for me?

Can I send a DTS or Dolby Digital signal from the computer's DVD player via the UA-101 or other relevant devices?

On Mac OS X, I can't use my Roland USB MIDI device simultaneously with the E-magic amt-8 or unitor-8.
