Hi, I'm currently trying to recreate the chord progression for some of my songs in Autotheory and it's proving to be a little challenging. It would be great if you could introduce the following abilities:

1. Trigger chords from pianoroll.
2. Import of midi file by drag and drop and save.
3. Analize and import chords from audio file and save.

4. Not about chords but it would also be great if you can allow us to step sequence our own arp patterns. Something simple like Reason's RPG-8 Arpeggiator which has both arp and step functionality would be great.

Thanks and keep up the great work with AutoTheory.
