Actually, I was sort of thinking that you could teach them--In all seriousness, drum patterns are a good way to start writing on a sequencer--

Not that I am any great shakes at this(I am a composer, and I use the sequencer and notation programs to compose, but I don't use them to make professional recordings) but I did start sequencing by editing and programing, one measure at a time, on one of those old Roland drum machines--

I don't let it out here much(there are some in this group with a real antipathy to MIDI stuff) but I am very fond of sythesizers and sequences, and I have a little 25 cent lecture about how music boxes were the first programable machines and that the cylinders and disks contained what amount to the first programs--

Any, you should start them working from the bottom up--once you understand how to write drum patterns, everything else falls into place--

If they are like the other million people (most are kids in one way or another) who work with MIDI, once you show them how to enter a few drum beats, they'll grab it and run with it--
