AX-Synth Editor 1.00Free
This is an application that lets you edit AX-Synth's parameters of your Mac. AX-Synth Editor contains the AX-Synth Librarian, a program that allows you to use Mac to manage AX-Synth tone settings as "libraries."
The AX-Synth features a sound generating engine that is derived from the Fantom-X (However, it is not multitimbral). This means that the parameters that can be managed on this editor are a subset of those on the Fantom-X.
