A big difference is CPU load: the bandlimited oscillators in the rj-library
aimed at mobile devices of some years ago use the transition splicing technique
because it's one of the fastest. It only needs a simple table lookup in
addition to the phasor~ etc.  that are running anyway. We even replaced the
tabread4~ with tabread~ to save even more CPU.
