Re: [bug] Crescendi (still) lead to unaudible notes in MIDI files

[Mats Bengtsson]

Yes, this is a long-standing bug, which occurs when you don't
specify any absolute dynamics before having a crescendo/diminuendo.
The problem is that LilyPond doesn't set any default volume to
start with. Actually, if you have a score without any dynamics
at all, the MIDI file will not contain any dynamics settings
either, so you get the default for the MIDI device you use.
