How well does it respond to velocity? I believe the Evolution series has several velocity curve settings--will it register very low velocity strikes? (It would be nice to assign all of those knobs to ADSR and filters, and not have to swivel around to use a mouse every time I want to experiment with a setting.

For that matter, would it be possible to boot up both an Evolution and a weighted keyboard, and just use the Evolution knobs to change the settings, while playing th weightedkeyboard? Or would this require that the Evolution had midi-thru, which it doesn't...?
