MIxpad help

What happning people. Im kinda new to this and wanted to know somthing about mixpad. Ive figured it out ok but when I try to record its telling me I need a device, I take it this means mic.

My question is this, in order to record the multi tracks onto my pc, do I still need the mic. I dont want to add vocals or anything I just want to record what ive made. Does anyone know how to do this. Or do I need the mic anyway. I thought that I would only need a mic if I was adding vocals, is this correct

PS> or if anyone knows a good sampling / editing system that I can do this with this would also be good.
