Remove cycling key maps (e.g. use o key to cycle between oscs)
Removed underline from certain parameter box names

* Namely those who now are not reached by cycling.
Fix erroneous step range for arp tempo parameter

* Using cursor to scroll would work, but the value sent to the Blofeld would
  be wrong. Using scroll/inc/dec would result in a max value of 127, and
  again the value sent to the Blofeld would be incorret.
* Seems to be something odd still, sometimes the value is off by one
  parameter (not ui) step value. Could be a rounding error. Still better
  than it was before this commit.
