Exciting addition, almost missed it:

Scripter

Extensible plug-in that can process or generate MIDI data using standard JavaScript.

This caught me by surprise too while looking through the midi fx drop down. Got it to repeat the note I play in a nice (not quite musical yet) pattern. Pretty excitig! I'd love to hear ideas for creative uses of this thing apart from making clever arps.

I know this is a niche feature but I think it's an important differentiator (and something that I love After Effects for).

I'm probably the only person who's excited to code up my own Arpeggiators and Rhythm pattern generators...

I don't even know what an Arpeggiator is, sounds cool though.

[widdershins]

If you play a chord into an arpeggiator, it... well, it arpeggiates it. In other words, it plays each note of the chord individually in a particular rhythm (e.g. 16th notes) in a particular pattern (e.g. up/down, up, random). Very, very common in electronic music.

[mitchty]

Cool I had no idea, I'm about as musical as... umm, yeah i've got no analogue.

Does it get scaled in specific patterns or is random ok?

[eropple]

Patterns, random, fast, short, whatever. Most packaged arpeggiators have all sorts of knobs to twist.
