I'm so loving your product. Every time I need it do something, it does it, or it's been included in v10 (which I don't have yet). Here's one I hope is included in v10...
I'm using MC9 to DJ on my laptop, and I need to be able to preview tracks before adding them to my playlist. It would seem that an extension to Zones or something like that should allow me have one zone dedicated to live output, and the other zone address only the headphone port. That said, the zone implementation would probably be a good first step implementation for you, but not ideal for the user (me), since today, when toggling between zones, the current media library context is lost. Thus, while I may have been previewing a song in my preview zone that I wanted to add to my live output zone playlist, I would have have to re-find that track... kind of a pain. This could be overcome by a setting to maintain media library context when switching zones. Heck, this would be a useful feature in and of itself.
BTW, I'm using a SoundBlaster Audigy 2 NX, and I know that other software (which I don't like as well as yours) is able to address the Audigy's stereo pair outputs independently to offer this preview functionality.
Thanks,
Jeff
