FATpick works great with your laptop's built-in microphone, an external USB or AUX mic, or guitar-to-USB connection like Rocksmith's Real Tone cable. But it's hard to beat the quality, performance and convenience offered by an external audio interface. Some users have had questions about how to use an audio interface like the Focusrite Scarlett Solo to connect their guitar to FATpick. This post has answers.
This guide is based on the Scarlett Solo - a simple but powerful device the maps two inputs (an XLR microphone and a 1/4" line/instrument/guitar cable) into a two-channel stereo output stream that connects to your computer via USB - but FATpick supports audio interface devices of all shapes and sizes, and in most configurations. We've selected the Solo as an example, due to it's popularity and simplicity, but the information and advice contained herein should also be helpful for and applicable to most other USB audio interface devices.
