Re: Tweaking midi tempo. Beats with sligthly different lengths..

[Mats Bengtsson]

It should definitely be doable, using some programming in Scheme. In
principle, the function should go through all the music and replace a4
b4 cis4
with a4*4/5 b4*11/10 c4*11/10
or whatever relation you want to use. However, if you want to handle
all possible rhythms within each beat, it will probably get quite
complex.

You may be able to find other software that can modify a MIDI
file correspondingly (search the mailing list archives, there was
recently a related thread).
