love the MIDI learn panel
I just love that you can map more than one UI element to the same MIDI CC and than control amount/intensity of modulation for each and single one of them via MIDI learn panel. Love it! One can make very nice and interesting patches that can be modulated to a great extent with one or few MIDI CC's. Just great!
Finaly the ModWheel can be used in a much more productive manner than just vibrating stuff :)
