Ok, here's another tip.

Masanao Izumo sent me a reply (see below), it works for me:
08:54:35 appel ~/usr/src/lilypond-1.3.140/mutopia/Coriolan/out$ timidity -id -k0
bassi-part.midi
Playing bassi-part.midi
MIDI file: bassi-part.midi
Format: 1 Tracks: 3 Divisions: 384
Text: Creator: GNU LilyPond 1.3.140.jcn1 .
...
Playing time: ~505 seconds
Notes cut: 0
Notes lost totally: 0

Hi,

Please try to use -k0 option:
% timidity -k0 filename.mid
It is possible that this is sound synchronization probrem.
TiMidity++ checks audio buffer size. If the current of audio buffer data has
no enough data, (this case usually occur when high CPU load avarage)
TiMidity++ automatically cut the some notes.
-k0 option disables this feature.
Some sound drivers (such as OSS from old linux packages), could
not get the current of audio data size, correctly.
Some sound cards use individual clock, not CPU clock. This type of
sound card, audio sampling time is different from CPU time. Then, the
audio sychronization is fail. To get the current of the audio data
size, it is need to use the specific audio driver interface. But old
of the OSS (or some version of OSS), there is no such interface! Too
cheap for multimedia!
If you have this type of sound card/driver, please try -k0 option.
