help with my Korg 12 tracker, and QS.1!!

[Pimpin420]

Hey, I got an Alesis QS.1 and a Korg 12 track multitracker. I'm not verey familiar with MIDI, or using this synthesizer, I'm used to more basic things. I've figured out how to plug everything in and play them but have quite a few questions. How do I loop the beat? How do I record the sounds from my keyboard onto a track on the Korg 12-tracker?Could somebody help please?
