# SendMIDI



SendMIDI is a multi-platform command-line tool makes it very easy to quickly send MIDI messages to MIDI devices from your computer.



All the heavy lifting is done by the wonderful JUCE library.

## Purpose

This tool is mainly intended for configuration or setup through Control Change, RPN and NRPN messages, but many other MIDI messages can be sent.



Here's a tutorial video about both SendMIDI and ReceiveMIDI, including some tips and tricks of how to use the command-line on macOS:

## Download



You can download pre-built binaries from the release section:

https://github.com/gbevin/SendMIDI/releases



Since SendMIDI is free and open-source, you can also easily build it yourself. Just take a look into the Builds directory when you download the sources.



If you're using the macOS Homebrew package manager, you can install SendMIDI with:

```

brew install gbevin/tools/sendmidi

```



## Usage

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.



These are all the supported commands:

```

  dev   name           Set the name of the MIDI output port

  virt  (name)         Use virtual MIDI port with optional name (Linux/macOS)

  list                 Lists the MIDI output ports

  panic                Sends all possible Note Offs and relevant panic CCs

  file  path           Loads commands from the specified program file

  dec                  Interpret the next numbers as decimals by default

  hex                  Interpret the next numbers as hexadecimals by default

  ch    number         Set MIDI channel for the commands (1-16), defaults to 1

  omc   number         Set octave for middle C, defaults to 3

  nrpn  number value   Send NRPN number (0-16383) with value (0-16383)

  clock bpm            Send 2 beats of MIDI Timing Clock for a BPM (1-999)

  mc                   Send one MIDI Timing Clock

  start                Start the current sequence playing

  stop                 Stop the current sequence

  cont                 Continue the current sequence

  as                   Send Active Sensing

  rst                  Send Reset

  syx   bytes          Send SysEx from a series of bytes (no F0/F7 delimiters)

  syf   path           Send SysEx from a .syx file

  tc    type value     Send MIDI Time Code with type (0-7) and value (0-15)

  spp   beats          Send Song Position Pointer with beat (0-16383)

  ss    number         Send Song Select with song number (0-127)

  tun                  Send Tune Request

  mpe   zone range     Send MPE Configuration for zone (1-2) with range (0-15)

  mpp   input          Configure MPE Profile initiator with MIDI input port name,

        manager        a manager channel (1-15), and desired member channel

        members        count (1-15, 0 to disable) (also uses MIDI output port)

  mpetest              Send a sequence of MPE messages to test a receiver

  raw   bytes          Send raw MIDI from a series of bytes

  -h  or  --help       Print Help (this message) and exit

  --version            Print version information and exit

  --                   Read commands from standard input until it's closed

```



Alternatively, you can use the following long versions of the commands:

```

  device virtual decimal hexadecimal channel octave-middle-c note-on note-off

  poly-pressure control-change control-change-14 program-change

  channel-pressure pitch-bend midi-clock continue active-sensing reset

  system-exclusive system-exclusive-file time-code song-position song-select

  tune-request mpe-profile mpe-test raw-midi

```



By default, numbers are interpreted in the decimal system, this can be changed to hexadecimal by sending the "hex" command.

Additionally, by suffixing a number with "M" or "H", it will be interpreted as a decimal or hexadecimal respectively.



The MIDI device name doesn't have to be an exact match.

If SendMIDI can't find the exact name that was specified, it will pick the first MIDI output port that contains the provided text, irrespective of case.



Where notes can be provided as arguments, they can also be written as note names, by default from C-2 to G8 which corresponds to note numbers 0 to 127. By setting the octave for middle C, the note name range can be changed. Sharps can be added by using the '#' symbol after the note letter, and flats by using the letter 'b'.



In between commands, timestamps can be added in the format: HH:MM:SS.MIL, standing for hours, minutes, seconds and milliseconds (for example: 08:10:17.056). All the digits need to be present, possibly requiring leading zeros. When a timestamp is detected, SendMIDI ensures that the time difference since the previous timestamp has elapsed.



When a timestamp is prefixed with a plus sign, it's considered relative and will be processed as a time offset instead of an absolute time. For example +00:00:01.060 will execute the next command one second and 60 milliseconds later. For convenience, a relative timestamp can also be shortened to +SS.MIL (for example: +01.060).



## Examples

  

Here are a few examples to get you started:



List all the available MIDI output ports on your system



```

sendmidi list

```



Switch the LinnStrument to User Firmware Mode by setting NRPN 245 to the value 1:



```

sendmidi dev "LinnStrument MIDI" nrpn 245 1

```



Light up LinnStrument column 5 on row 0 in red by setting CCs 20, 21, and 22 to the column, row and color:

  

```

sendmidi dev "LinnStrument MIDI" cc 20 5 cc 21 0 cc 22 1

```



Load the commands from a text file on your system and execute them, afterwards switch to the "Network Session 1" port and send it program change number 10:

  

```

sendmidi file path/to/some/text/file dev "Network Session 1" pc 10

```



Change parameters on a Yamaha FS1R over SysEx:



```

sendmidi dev "iConnectMIDI4+ DIN 1" hex syx 43 10 5e 10 00 10 00 7f

```



## Text File Format



The text file that can be read through the "file" command can contain a list of commands and options, just like when you would have written them manually on the console (without the "sendmidi" executable). You can insert new lines instead of spaces and any line that starts with a hash (#) character is a comment.



For instance, this is a text file for one of the examples above:

```

dev "LinnStrument MIDI"

# set column 5 on row 0 to the red color

cc 20 5

cc 21 0

cc 22 1

```



## Building on Linux



To build SendMIDI on Linux you need a minimal set of packages installed beforehand, on Ubuntu this can be done with:



```

sudo apt install build-essential pkg-config libasound2-dev

```



After that, go to the `LinuxMakeFile` directory



```

cd Builds/LinuxMakeFile

```



and build the binary by typing `make`



```

make

```



The resulting binary will be in the `Build/LinuxMakeFile/build` directory and can be moved anywhere appropriate on your system, for instance into `/usr/local/bin`:



```

sudo mv build/sendmidi /usr/local/bin

```



## ReceiveMIDI compatibility



The input of the SendMIDI tool is compatible with the ReceiveMIDI tool, allowing you to play MIDI message sequences that were stored earlier. By using Unix-style pipes on the command-line, it's even possible to chain the receivemidi and sendmidi commands in order to forward MIDI messages.



ReceiveMIDI can be downloaded from https://github.com/gbevin/ReceiveMIDI
