New P600fw alpha (october 12)

Notable changes:
- Adding 2 track Roland JX3P style step sequencer.

Step sequencer usage:
- Press SEQx to activate the sequencer, it will wait for you to play a note to start playing.
- Press SEQx again to force start.
- Press RECORD while the sequencer is active to edit the sequence:
  - Highest C: add rest.
  - Highest B: add tie.
  - Highest Bb: undo last add.
  - Any other note: add to sequence.
  (the display shows the current step)
