Sorry. More haste, less speed. I meant \shiftDurations. It might
require other things to be adjusted too: \time is given as an example
here. This code was developed some years ago, so there might be better
ways of doing it now.
\version "2.19.40"
music = { c'4 4 4 4 }
{ \time 4/4 \music }
#(define RF 1) % 1 to double note values, 2 for unchanged, 4 for
halved, etc.
{ \shiftDurations #(rationalize
(inexact->exact (- (/ (log RF) (log 2)) 1))
1/10) #0
{ \time #(cons 4 (* RF 2)) \music }
}
