I'd love to find a command-line MIDI file player that will use ALSA MIDI (not its own
internal synth), and also will accept arrow keys or some other key commands on stdin to
fastforward, rewind, pause, play, etc.
There seem to be a ton of MIDI players for the command line, but they all seem to not be
interactive. I can't seem to figure out if ecasound can do the fast forward and rewind
stuff, and I find Timidity to bewildering to contemplate.

Ecasound uses Timidity to play .mid files and fails to seek:

Pausing would be easy, but MIDI controller changes can be sent at any
time and affect all current and following notes, so when forwarding, the
player would have to send all intermediate controller messages, and when
rewinding, it would have to replay all controller messages from the
beginning of the file. It is possible to drop messages that are
overwritten by a later change to the same controller, but this does not
work for SysEx messages whose format isn't known.
Best regards,

Hmm. How do programs like Rosegarden do it then? I've never had trouble seeking in RG,
for example, or looping or any of that.
If I can't find a command-line tool, then of course I'll end up using RG, which is
fine, but I'd rather find a non-gooey way to do it if possible.

Maybe you can pipe the output of timidity to mplayer. If it doesn't work in a pipe you
can write a shell script to write it to a temporary file then play it in mplayer. The
script would look something like:
timidity -Ow $1
mplayer `basename $1 .mid`.wav
rm `basename $1 .mid`.wav
This above script will only work if the file is .mid I think though.

recent midish versions can almost do that, but not with the
arrow keys, unfortunately. It's controlled from stdin,
supports start/stop and relocate (for rewind/fastforward).
ex:
dnew 0 "28:0" wo # use 28:0 port for output
import "myfile.mid" # import file to play
p # play
s # stop
g 17 # go to measure #17
when you change the position, it restores the states of all
controllers and handles the note-off events of skipped
notes.

It looks like it could also do a lot of useful stuff, but I find it bewildering and the
documentation not quite complete.
A few questions, if I may?
1) How do you get it to pause? Not stop, which is "s", and then it resets the
position back to zero, but just momentarily pause and keep the position at wherever it is
at?
2) How can I route output to a different channel when I'm *playing* a MIDI file? I
found documentation on how to route and filter when recording, but I need to do the
filtering/routing at playback time.
3) Is there any rudimentary editing capability? i.e., cut the file keeping only events
from range X-Y and J-K?
I'd also like to try out Julien's modified C++ version of it too.
Thanks to you and Julien for reccommending midish.

there's no pause function yet; i guess because nobody needed
this until now.
AFAICS the code to pause would be the same as the code to
stop, except that it must not restore the initial position.
2) How can I route output to a different channel when
I'm
*playing* a MIDI file? I found documentation on how to
route and filter when recording, but I need to do the
filtering/routing at playback time.
there are two options:
- edit the file to change the channel of the events;
possibly you can save the file, or apply the change
to only a portion of the file. Ex.
ct mytrack # set current track
g 17 # go to measure #17
sel 16 # select 16 measures
tevmap {any piano} {any organ} # map piano->organ
assuming ``piano'' and ``organ'' are channel names registered
with ``onew'' function (you can use dev/chan numbers instead,
though; ex ``{0 1}'' instead of ``piano'')
- use two midish processes, one to play the file
and one to handle the routing only, handly to experiment
in realtime or to use other midi software.
3) Is there any rudimentary editing capability? i.e.,
cut
the file keeping only events from range X-Y and J-K?
yes, example:
ct mytrack # select track ``mytrack''
g 17 # goto measure #17
sel 16 # select 16 measures
ev {note {} 60..72} # select notes 60..72
tclr # delete them
the following functions might be useful for editting, you
could look at their description in the manual: g, sel, setq,
ev, tcopy, tpaste, tclr, tcut, tins, tquant, ttransp,
tevmap, tren, mcut, mins, mdup, mend, t, ls.
