Hi,
Let's try the converse, and see if anyone has ideas about where the problem might be occurring
The answers to the following questions may prove helpful:
1. What operating system are you using? (eg. XP, Vista, Win 7, etc.)
2. What kind of computer do you have? (I've found that my kids' ASUS netbooks have boatloads of special shortcuts that can be frustrating til you get them all figured out and memorized. One son was getting no sound til he stumbled on a shortcut that muted his soundcard.)
3. What sound card to you have?
4. What MIDI playback device are you using when you use Notation Musician or Notation Composer? (eg. GS Wavetable, Garritan Personal Orchestra, ....? )
5. If you're using the GS Wavetable in (4), do you have other audio applications on at the same time that use ASIO? The GS Wavetable is known to interfere with ASIO, and it may happen conversely as well.
ttfn,
Sherry
