A program to manipulate SMF (Standard MIDI File) files.
midicomp willboth read and write SMF files in 0 or format 1 and also read and writeits own plain text format. This means a SMF file can be turned intoeasily parseable text, edited with any text editor or filtered throughany script language, and 'recompiled' back into a binary SMF file.

Dec 02, 2017 Click on the menu “File” “Export Midi file to TEXT” The MIDI file will be then exported to a text file named “FileName (Dump).txt” located in the same directory as your original MIDI file, and will be displayed in your default text editor (notepad, notepad etc ).

Usage
To translate a SMF file to plain ascii format
To translate a plain ascii formatted file to SMF
Format of the textfileThe <> have the following meaningMisc notes
Channel numbers are 1-based, all other numbers are as they appear in themidifile.
<division> is either a positive number (giving the time resolution inclicks per quarter note) or a negative number followed by a positivenumber (giving SMPTE timing).
<format> <ntrks> <num> are decimal numbers.
The
<num> in the Pb is the real value (two midibytes combined)
In Tempo it is a long (32 bits) value. Others are in the interval 0-127
The SysEx sequence contains the leading F0 and the trailing F7.
In a string certain characters are escaped:
' and are escaped with a
a zero byte is written as 0CR and LF are written as r and n respectivelyother non-printable characters are written as x<2 hex digits> When -f is given long strings and long hex sequences are folded by inserting<newline><tab> . If in a string the next character would be a space ortab it will be escaped by
midicomp will accept all formats that mf2t can produce, plus a number ofothers. Input is case insensitive (except in strings) and extra tabs andspaces are allowed. Newlines are required but empty lines are allowed.Comment starts with # at the beginning of a lexical item and continuesto the end of the line. The only other places where a # is legal areinsides strings and as a sharp symbol in a symbolic note.
In symbolic notes + and # are allowed for sharp, b and - for flat.
In bar:beat:click time the : may also be /
On input a string may also contain t for a tab, and in a foldedstring any whitespace at the beginning of a continuation line is skipped.
Hex sequences may be input without intervening spaces if each byte isgiven as exactly 2 hex digits.
Hex sequences may be given where a string is required and vice versa.
Hex numbers of the form 0xaaa and decimal numbers are equivalent.Also allowed as numbers are 'bank numbers' of the form '123. In factthis is equivalent to the octal number 012 (subtract 1 from eachdigit, digits 1-8 allowed). The letters a-h may also be used for 1-8.

The input is checked for correctness but not extensively. Anerrormessage will generally imply that the resulting midifile is illegal.
channel number can be recognized by the regular expression
/ch=/ .note numbers by /n=/ or /note=/ , program numbers by /p=/ or /prog=/ .Meta events by /^Meta/ or /^SeqSpec/ .Text events by /'/ , continued lines by /$/ , continuation lines by /$t/ (that was a TAB character).
Examples
To convert a huge number of MID files try some variation of this command...
In awk each parameter is a field, in perl you can use split to get theparameters (except for strings).
The following perl script changes note off messages to note on withvol=0, deletes controller 3 changes, makes some note reassignments onchannel 10, and changes the channel numbers from channel 1 dependingon the track number.
and this is the corresponding awk script.
This genius, free, open-source tool, SendMIDI, from Geert Bevin is going to make life so much easier for developers or anyone wishing to send MIDI messages straight from their computer's command line.

The incredibly talented music app programmer Geert Bevin has worked on projects you'll probably be aware of, from LinnStrument to Moog Model 15. Late on Friday he announced on his Facebook page the release of the free SendMIDI, a multi-platform command-line tool makes it very easy to quickly send MIDI messages to MIDI devices from your computer. It uses the awesome JUCE library.
As Geert explains, 'after years of muddling around when having to send NRPNs, CC messages, specific Note On/Off messages, and other MIDI messages to MIDI devices ... I decided it was time to write a little tool that makes sending MIDI messages from the command line very easy. So after a couple of hours of work today, here's SendMIDI, hope you'll find it useful too!'
While SendMIDI is primarily intended for 'configuration or setup through Continuous Control, RPN and NRPN messages', Geert has made sure many other MIDI messages can also be sent.
SendMIDI is free, open-source and easy to build yourself. You can download pre-built binaries from the release section: https://github.com/gbevin/SendMIDI/releases
When it comes to using SendMIDI it couldn't be easier. Below, Geert Bevin explains how. You can find out more on the SendMIDI Github page.
'To use it, simply type 'sendmidi' or 'sendmidi.exe' on the command line and follow it with a series of commands that you want to execute. These commands have purposefully been chosen to be concise and easy to remember, so that it's extremely fast and intuitive to quickly shoot out a few MIDI messages.'
