Kronut is an editor for Korg Kronos set lists. It has two modes: set list load/save and slot text editor. The first mode lets you save set lists to readable and editable files in a format like Markdown or Org Mode, and it can read those files and save them back to the Kronos. This lets you edit global set list settings, edit slots, and move them around within the set.
Kronut also lets you edit individual slot names and comments without the intermediate step of saving the whole set list to a file first. In this mode you can't move slots around using Kronut.
To get Kronut, you'll need to download the source code and compile it.
You'll also need to install the http://portmedia.sourceforge.net/portmidi/
library and headers. If you use Homebrew then you can
install it via brew install portmidi.
To compile the code, run make.
To compile and run the tests, you'll need to install
Catch2. The easiest way to do that is
via brew install catch2. After you've done that you can compile and run
the tests by running make test.
To install kronut system-wide, run make install. By default the
executable is installed to /usr/local/bin but you can override that with
the prefix, exec_prefix, or bindir variables. For example, make prefix=/tmp install would install kronut at /tmp/bin/kronut.
$ kronut save 2 my_set_list.org
$ # ...edit that file...
$ kronut load 2 my_set_list.org
$ # or you can edit slots' comments more directly
$ kronut edit
Run kronut help to see all of the command line options.
Kronut tries to auto-detect the Kronos' MIDI input and output ports, but if
it can't find them you can specify them on the command line. To list all of
the available input and output ports, run kronut list.
Kronut's save command works by reading a set list from the Kronos and writing it to a file (or to stdout). The load command reads from a file (or stdout) and saves it to the set list you specify.
Files are written in either the Markdown
or Org Mode format. The default is Org Mode. To use
Markdown, use the --format command line argument.
The files that Kronut reads and writes are text files. Here is the beginning of an example set list file that I saved from my Kronos. I prefer Org Mode, so that's what you're seeing here. Markdown mode looks very similar.

The first line is a top-level header that contains the set list name, in this case "Learning These".
After that is a table containing set list settings like slots per page (4, 8, or 16) and EQ bypass (0 (EQ off) or 1 (EQ on)).
Next are all of the slots in the set list. Each slot starts with a second-level header with the slot's name. Next come the comments, if any. Finally, there is a table containing the slot's settings.
That's it.
Whenever a slot name or comment you enter too long, it is truncated before it is sent to the Kronos. When that happens, Kronut outputs the slot number and name and tells you if the name, comment, or both were too long.
The "edit" command will start a simple text-only program that prompts you for one-letter commands, like this:
Type 'e' to edit current slot, 'p' print, 'd' dump, 'q' quit, 'h' help.
Kronut can't save the set list itself. Remember to do that.
kronut> h
e: edit current slot
r: re-edit (does not get data from Kronos)
p: print current slot
d: dump current slot
h: this help (also '?')
s: prints the names of each slot in the current set list
q: quit
kronut> e
kronut> q
$
%yping e and hitting return will download the name and comment of the
currently selected set list slot into a Markdown file and open it using your
editor. When you are done editing the name and comment, save your changes
and quit your editor. Kronut then sends what you've edited back to the same
set list slot.
You specify the editor program to run by defining the $VISUAL or $EDITOR
environment variables. If neither of those are defined, vi is used. If the
environment variable $KRONUT_VISUAL_OPTIONS is defined it will be passed
to the editor command.
The slot name must be a single line after the "# Slot Name" Markdown header. Names longer than 24 characters will be truncated to fit.
The comments must start after the "# Comments" Markdown header. The comment will be truncated after 512 characters.
Whenever a slot name or comment you enter too long, it is truncated before
it is sent to the Kronos. When that happens, Kronut tells you and gives you
a chance to re-open your editor with the longer data that you saved using
the r command. That way, if you want to re-edit the slot you'll have all
that lovely text you added that was truncated.
In "edit" mode, Kronut doesn't know how to tell the Kronos save the set list itself. After you've changed one or more slots, you must manually save the set list on the Kronos.
If you're using the Emacs emacsclient utility (like I do), you'll need to
call server-edit (C-x #) after saving the buffer to tell emacsclient
that you're done editing the file. Sometimes I'd like to cancel the edit,
but I don't know of a built-in way to tell emacsclient to exit without
saving the buffer first. So I wrote this function:
;;
;; When editing emacsclient buffer, use this to send a non-zero status back
;; to emacsclient.
;;
;; https://superuser.com/questions/295156/how-to-set-the-exit-status-for-emacsclient/542916
;;
(defun buffer-kill-emacsclients ()
"Sends error exit command to every client for the current buffer."
(interactive)
(dolist (proc server-buffer-clients)
(server-send-string proc "-error killed by buffer-kill-emacs")))When this function is called, Kronut will print the error message "killed by buffer-kill-emacs" and nothing will get sent to the Kronos.
Comment brightness (adjusted from with the full-screen slot comment display) is a global setting. It is not stored with the slot or the set list, so Kronut can't save it or let you adjust it.

Find out where slot MIDI track is stored in the slot struct. It's only for songs.
-
Set list control surface mode: figure out values (and bit range in struct) so they can be presented as text instead of a number.

Keyboard track is only for songs; change the label?
