Updated to 2.5 & I have my floor unit connected to my computer via the USB. I practice with mp3s from my computer & they would come through the Helix. Now they are not. Any ideas why not? The Helix is showing on my computer as a playback device & is enabled but the audio is not going through the Helix like it should. My Global settings for the ins/outs on the Helix for USB say: Multi/USB in 1/2 Destination. I attached a couple screen shots.
