Re: [Jazzplusplus-user] File format question: audio/sample triggers

[Keith H. <par...@gm...>]

I think the extent to which midi files squeeze data (variable-length
delta times??) is pointless in this day and age.  For how little space
the files take up, they should at least be human readable, in my
opinion.  Some newer standard really ought to move in and take over.
