I hooked up the VK to the kb today, and it's going to work just fine for the mic, but I'm having an issue when I also plug my ipad into the aux in (on the VK) I get instant feedback, even if the volume is at zero. I'm looking through the manual, and doing some research on why now.
I found another shortcoming - the song mode only allows 99 MP3 songs, no matter how many you have on your disk. There may be formatting issues here, but I followed the directions, and formatted the USB drive in the kb first. There's 999 locations for saving user recorded songs, but I don't understand why it won't read all the songs on my flash drive. This is a first. It's not like they are loaded into the kb, itself - they reside on the USB stick. Puzzling.

I still like it alot, but I'm finding out what it CAN, and CANNOT do. It's a process, but either way - it's coming to the winery in July.
More info as I learn it.
