Ksp reference Manual

Creating, Importing and Exporting MIDI files
When you initialize an instrument, an empty MIDI object is initialized with it. You can either start
editing the object by defining a buffer size and inserting events, or by inserting a whole MIDI file.
If you want to create a MIDI sequence from scratch, you first need to assign a buffer size, which
effectively creates a number of inactive MIDI events. From this point you can activate, i.e. insert,
and edit MIDI events using the MIDI event commands.
You can also load a MIDI file to use or edit the data in a script. Depending on the command and
variables you use, this will either be combined with any existing MIDI data, or will replace the exist-
ing data. It should be noted that loading a MIDI file is an asynchronous command, and thus the
common asynchronous loading commands and working methods apply.
MIDI objects can be exported from KONTAKT either by using the 
save_midi_file()
command,
or via a drag and drop enabled label element. In either case, it is possible to define the export
area, both in terms of start and end times, as well as the start and end tracks, by using the
mf_set_export_area()
command.
