Hi,
I stand corrected, the PMDX-424 is Mach4 only. I thought it had a pre-existing Mach3 plugin, but not so.

No problems though, Mach4 is new and in some respects quite different to Mach3 and so will cause you some hand wringing. Once you start getting the
hang of Lua, Screen Editing, modular scripts and so on, and I don't mean to gloss over the learning curve, it is steep but the reward is very VERY satisfying.

As you may have gathered PMDX is a very VERY 'safe pair of hands', you'll never regret buying from them.
