I'm trying to use a USB mic with Studio One 4. I know that this is a tricky issue that requires running the USB mic through ASIO4ALL. Pretty annoying, but fine. Unfortunately, ASIO4ALL doesn't seem to support playback, meaning that if I'm trying to use it to record vocals for a backing track, I can't hear the backing track. If I switch to my AudioBox, I can hear the backing track but can no longer record through the USB mic. Is there a fix for this, or any plans to make it so Studio One 4 supports USB mics through Windows Audio?
