I have a guitar to USB plug in that I use to record audio on my PC. It works just like any PC microphone, it just plugs into guitars instead. I can use it with other software and I see that it is working.
Now when I look at Sampletuides options for "input" to record from, there are dozens and dozens of options. Things named like "Magix low latency 2016 1+2", but no option for my computer hardware, USB or even any of the microphones I have to plug into my computer.
The only items that appear on the input list are these "Magix low latency 2016 1+2" but none of those selected inputs play my guitar over the software.
What is the problem?
