invoking midi2ly and using sustainup and sustaindown

[Ridwan Sami]

i'm kind of new at this lilypond thing and i'm having
two problems

first off, i'm not even sure if i'm doing this right
but i have lilypond installed thru cygwin on a windows
xp and i am typing into the bash shell:

$ midi2ly wee.mid

and getting

Traceback (most recent call last):
  File "/usr/bin/midi2ly", line 43, in ?
    import midi
ImportError: dlopen, Win32 error 126

can anyone tell me what i am doing wrong?

secondly, i have a .ly that compiles just fine to both
pdf and midi but as soon as i add in \sustaindown and
\sustainup, i get a bunch of errors in the heading
when compiling.

this is how i am doing it:

c4 c c c

is changed to

c4\sustaindown c c c\sustainup

i am running 2.2.5, and i've read this section in the
manual. can anyone help me?

thanks for your time.
