Blue Jinn
Rider of the ARPocalypse
For US$39 it's worth checking out. Demo is also available that interjects noise every few minutes. I haven't done a side by side with the real thing, but it mimics the look including the plethora of on/off switches and sliders. That can get a little cumbersome with a mouse, but it comes with a lot of presets and the ability to save your own, something that is actually lacking on the real thing. Sounds decent on its own if you're looking for an ARP Omni and a stripped down ARP Odyssey (technically it's the Solus) types sound and it kinda mimics the single trigger non-legato on the bass section. It adds a few chorus and reverb effects too.
