I'm not quite sure how to use it correctly yet but I suppose a typical usage would be :
\time 6/8 % btw \tempoChange 8 1/2 0 { \skip 2.*4 | } ^ I.e. : To slow down every 8th during 2.*4 to reach (and keep (0)) a tempo half the speed it was. I get inconsistent results either : - working correctly - Hanging forever after [8][16][24][32][40][48][56]… - Or (with 2.25.8) : MIDI output to `output.mid'...[1] 1213296 floating point exception (core dumped) > it has worked for at least a year or so here. No MWE for now but will provide if needed. -- Pierre-Luc Gauthier
