If you use an EWI 4000S and HATE the seemly abandoned Vyzex editor for it? Fear NOT fellow EWI players, Joseph Sheedy has come to the rescue. He has successfully compiled and released a build of the EWITool for OS X. And it works….though it is a little wonky. The interface is a little weird, and the Set Library doesn’t seem to work. The EWI Patch Set does work, which is cool. It is a community group where you can share patches you make. There are actually some nice ones there.
So, go check out EWITool. And grab the Mac version.
