Record MIDI data from kslider ?

I looked at some help files but feel confused about seq, and detonate, etc. I would like to know how I can record MIDI messages from what I play (with mouse click) on kslider (keyboard GUI) and playback the recorded MIDI data later.

Which object should I use to record MIDI data from kslider ?
Are there some example patches I should take a look at ?

Thank you very much.
