I'm using a Nord Stage and a Windows 10 laptop, and I want to record an audio (not MIDI) track on top of existing tracks. So I'd like to hear the keyboard and the backtrack, and record just the keyboard.
I tried to just connect the keyboard to the line in. But then I get a terrible latency. Then I found ASIO4ALL drivers, and using that in combination with Ableton Live, the latency problem is solved. But ASIO4ALL uses the output exclusively so then I can hear either just my keyboard input or just the backtracks, not both at the same time.
I've also got a simple Behringer XENYX 502. Perhaps I could use the tape in and out ports to mix keyboard in and e.g. phone in on which I play some backtrack. But that's very inconvenient because each time I want to update the backtrack with a newly recorded track I've got to transfer it to my phone first.
Is an external audio interface going to help me out here? There's a huge price range and a lot to choose from, what would be a simple, cheap solution to my challenge?
