I posted a full AN200 editor I made in MIDIDesigner Pro 2 for IPad. This is a full SYSEX implementation of the AN200 and will work with the plug in card and should work with AN1X. My AN200 is now a fully programmable one knob per function synth in realtime. It's really a pretty incredible instrument.
