Was wondering the same thing! If you look in the manual, the 5.1 chart page for MIDI banks (p. 34) specifically says that banks 7 and 8 go down to octaves -1 and -2. Am I reading this wrong? Maybe I'm mixing up the Keyboard mode and those MIDI mappings in section 5.1? Since only 13 pads are active in Keyboard mode, I don't understand where the mappings in section 5.1 come from or are used. Anyone else on this? Thank you!
