This is Stefan Meinlschmidt’s patch editor for the Akai EWI 4000 s wind synthesizer.
ewi4000s-editor is free software. It is licensed under the terms of the so-called MIT-license.
TL;DR: ewi4000s-editor is a sound editor for the Akai EWI 4000 s, meant to run under Linux.
The Akai EWI 4000 s is a synthesizer and stores 100 sound patches. Unfortunately its controls do not allow you to change those patches directly on the instrument. Instead some software is needed that talks the appropriate MIDI commands.
One such software, the UniQuest Editor/Librarian, comes bundled with the instrument. It runs under Windows, looks aggressively shiny (90s style), and its librarian functionality seems to be severe overkill for something simple as tweaking a few dozend parameters. At least it can be startet under Linux using Wine. All in all I don’t like it.
Consequently I wrote my own, simpler, totally non-shiny replacement. It needs Python 3.4 (I think) and either ALSA or Windows. I.e. it is made for Linux but might also run under BSD and maybe even MacOS (with some ALSA installed), and I have seen it run under Windows (without ALSA but with some suitable Python installed).
So now you have the choice to not like ewi4000s-editor instead of UniQuest, or you can hate both and go for another competitor instead: EWItool.
In order to run ewi4000s-editor you need a PC with an OS either supporting ALSA (e.g. Linux) or Windows Multimedia (Windows). You also need Python 3.4 (I think) or newer installed.
In order to use ewi4000s-editor you need an EWI 4000 s (the 5000 or the USB won’t do) and some kind of MIDI interface that works under Linux (or whatever OS you are trying to run ewi4000s-editor on). Use two MIDI cables to connect the EWI’s MIDI out to the interface’s MIDI in and the interface’s MIDI out to the EWI’s MIDI in. Hook up the interface to your computer and you are in business.
