Geoff,
Here's what works for me: I write out the drum part using the staff function in cakewalk. Here is a link to a a four bar view from the solo section:

For me this has several distinct advantages, I know what the drum part is <grin>, I can then 'audition' the drum part on various midi outputs - be it an internal sound card, external rack or drum machine.
BTW, since the tympani part is actually substitued for a bass part, it was written on a separate staff and not included on the drum track.
The only draw back to pre programmed loops is that you can't edit the actual parts,( e.g. changing the hi-hat is from closed to open on the last 16th of the beat four...)
just something to think about, -Rick
