I used Cubase 7 element. I am configuring my device to record. When I clicked record, the voice track was recording but record both the backing track and voice. I don’t know how to turn off it.
I’m using Windows 7 ultimate OS and Roland Octa capture sound interface.
Any one can help me for this iuse 
Thank you!
It sounds like your OS output is being looped by your audio interface. In Devices, Device Setup, VST Audio System, what is your ASIO Driver? What is your Input Latency?
I would suggest verifying that your Roland device does not have any “loopback” or other internal system recording settings turned on.
I’ve solve this iused. Thank you buddy
