This thing is amazing!!! It does have a bit of a learning curve -- you need to figure out in the context of your particular DAW how to route things correctly. But it's just pure magic after that. The basic idea is that you have two MIDI sources per instrument: (1) a pattern, (2) some chords over which to execute that pattern. You can generate very complex patterns in a short period of time. It is just far beyond any other arp, and I have bought a lot of them. I had the idea for something like this in my head, but it took me a long time to finally discover it and figure out that someone actually made this.
