Actually, the unique thing of the 402 series is that it actual streams audio out the back end, which is all in stereo.
You can capture your performance through the following:
1-Rec 'N' Share App- which is a free App you can download on your smart device and plug into the 402 module with a USB A-B cable, "basically a printer cable," along with a camera connetion kit. "A lot of versions exist out there." Right now this App is only compatible with Apple Products.
2-Plug directly into any DAW, and you can bounce it directly out as an audio wave or mp3 file
The 402 Series doesn't have a USB port where you can record directly to a stick.
Let me know if you have anymore questions Hary, happy drumming!
