I'm using a USB keyboard for VITA but I get no sound or recording of the notes I type while using vita. I can see the keys moving on the screen as I press them on the Keyboard.

2
Mixed several wavs in a VIP, now when I go to record I get Delay while recording. Opening up a new VIP there is no Delay.

3
Computer noise I read that the buffer rate needs to be changed to stop the pops and clicks while playback and recording, but what is a normal rate cause I seem to be getting them still.

Please help...
