The accedit project page

The Cavagnolo Odyssee Pro-Orchestra is an electronic accordion with a MIDI interface. It is a wonderful instrument with a lot of settings. In fact, there are so many that it can take a lot of time for a musician to tune the instrument. Unfortunately, there is no easy way to do it. Functionality is provided to upload or download the settings of the instrument to or from a computer, but there's no software to do something useful with it and Cavagnolo has no intention to develop it. This is a pity, since it would make the instrument even more valuable than it already is. Many owners of the instrument would love to have some kind of editing software that makes it easier to modify settings. It will save them literally hours that could better be spent actually playing some music and will make the instrument more valuable. The goal of this project is writing such an editor with an easy-to-use graphical user interface.

Accedit is Free Software. It is written in Java 2 (Standard edition, v1.4.2) so the application can be run on different operating systems.

A major difficulty in this project is the format in which the settings of the instrument are saved. This is done using MIDI System Exclusive Messages, but no details of the contents of the message are released by Cavagnolo (although the MIDI standard specifies that this is required). Fortunately, this is already (almost) solved thanks to the hard work of Eddy Buyck.
