The FTP site appears to be down.
I'm already a little bit disappointed and frustrated with the way the presets are "hidden" from the VST host I use. I had hoped to use these synths in a live setting and be able to set up scenes with different presets loaded (and quickly switch among them) but the host I use expects them in FXB/FXP format.
I'm hoping to be able to download the presets and use them in some way with my host.
