DESCRIPTION
smfsh, an "SMF shell", is an interactive, command-driven frontend to
libsmf, useful for modifying MIDI files by hand. It started its life
as a debugging aid for libsmf.
There are four groups of commands: SMF level, track level, event level,
and others.
SMF LEVEL COMMANDS
SMF level commands display or change properties of smf (i.e. the MIDI
file) as a whole.
save file
Save a file. If the file name is not given, the last file name
is used.
Note that this will not ask for confirmation.
load file
Load a file. If the file name is not given, the last file name
is used.
Instead of using "load", you can pass the file name on the com‐
mand line.
ppqn new-ppqn
Show (if used without parameter) or change PPQN (Pulses Per
Quarter Note, aka Division).
format new-format
Show (if used without parameter) or change format.
tempo Show tempo map. Tempo map is computed automatically from the
SMF contents - to modify a tempo, just add a Tempo Change event
using "add" command.
length Show total length of the song. Just like the tempo map, file
length is computed from the SMF contents.
TRACK LEVEL COMMANDS
Track level commands display or change properties of tracks. SMF may
contain one or more tracks.
tracks Show the list of tracks in the SMF.
track track-number
Show details of a track (if called without parameter), or select
track with a given number - for example in order to display
("events") the events it contains.
trackadd
Create new track.
trackrm track-number
Remove the track. If the track number is not given, this will
remove the track currently selected.
EVENT LEVEL COMMANDS
Event level commands display or change properties of events. Events
are grouped into tracks. Track may contain any number of events,
including zero.
events Show the list of events in the current track.
event event-number
Show information about a current event (if used without parame‐
ter) or select the event.
add time-in-seconds midi-message-as-hex
Add new event to the currently selected track.
rm event-number
Remove the event. If the event number is not given, this will
remove the event currently selected.
OTHER COMMANDS
There are three commands in the "other" category - "help", "version",
and "exit". Their meaning should be self expanatory.
