* Three Midi values for each instrument - '''Bank MSB''', '''Bank LSB''' and '''Program Change'''. Some older instruments will only have a Program Change value.
=== Instrument set files file overview ===
As mentioned above, instrument sets are stored in an <tt>.instrument-set</tt> file. This is a plain text file that can be edited in any text editor.
If you prefer, there are editors available that are specifically designed to help with editing a JSON file. E.g. http://www.jsoneditoronline.org/ will let you edit the text from a <tt>.instrument-set</tt> file directly online, including indicating (roughly) where there are any errors in the file format, and showing you how it understands the data in the file.
=== Instrument set files file detail ===
We strongly suggest you start from an example <tt>.instrument-set</tt> file. This will give you the outline to base your instrument set on. From there the task is mainly one of copying and pasting, and inserting your instrument details.
