I've got no evidence, but I don't expect any considerable performance loss. TeX's macro mechanism is highly performant, thus expanding a short macro shouldn't be much slower than looking up a register content. (Perhaps it's even faster? I don't know ...) > For typing short pieces this shouldn't be a problem. But for rather big > scores? I remarked already that adding lyrics to a piece using musixlyr > considerably slows down PMXing and TeXing. That's regrettably true, but it has nothing to do with the register/macro choice. It's a rather general property of musixlyr, based on the fact that the necessary lyrics analysis (i.e. the splitting into syllables) can be accomplished with TeX data structures only in squared-degree, not linear, execution time (related to the length of the lyrics input). It shouldn't have any significance on PMXing, though.
