You'll need an audio interface like the BandLab Link Analog for mobile devices or the BandLab Link Digital for computers in order to use an instrument or microphone on BandLab. There are plenty of other audio interface manufacturers to choose from, but please make sure it's compatible with the device you're planning to use it with.
Once you have an audio interface;
- Connect a quarter-inch or XLR cable from your instrument or microphone to the audio interface
- Connect the audio interface to your mobile device or computer
- Create a Voice/Mic, Guitar, or Bass track and start recording!
