I have a physical electronic drum kit, and I have connected the cables successfully. In the song editor, I have my drum kit selected as the input, but I'm not sure how I am supposed to record what I am playing, and then save it as a mp3 file.

Please forgive me for being a newbie. I have a physical electronic drum kit, and I'm trying to record it using LMMS. I have the cables connected and working, but I don't know how to get LMMS to detect and record what I'm playing on my kit.
