Rob, isn't TC Helicon a vocal harmonizer and not an audio interface? That might be your problem but I don't know for sure.

Try running your on board sound card (audio interface) and see what happens. If it runs ok then the problem is with the TC Helicon. If so then you may need to invest in a audio interface.


Life is short so make sure you spend as much time as possible on the Internet arguing with strangers.
