Do you like your Oberheim Matrix 6 or 1000 synths? I've got some great news for you, an OS X editor is in beta right now. It's a work in progress right now allowing already basic patching, final release is expected in a few months…
M1000X is freeware :) but OS X 10.3 and up only. "Because this beta version is not fully tested, it is highly recommended that you make a backup of your synth's current patches (such as by dumping the patch data to a computer, or using the Matirx-6/6R's cassette interface), prior to using M1000X to edit patches."
