Is it possible to get a tempo definition like \tempo 8*5 = 100?
Do you want it displayed somehow, or simply defined?
If the latter, simply say \tempo 8 = 500.
If the former, you'll need to be more specific about how you want the display (e.g., with notes in markup, or whatever).
Hope this helps!

It would have to be the former, you know, so it's difficult. Right now, I've just done it in markup with \note #2 #UP ‿ \note #8 #UP. I was just wondering if there's another way, mainly because I'm too lazy to fiddle with the baseline to get the tie where it should be.
