* Requires Bitwig 5.3+

* Implemented adaptive scrolling for play position as well as the loop start and length on all devices which provide these functions.
* ROTO CONTROL
  * New: Support for stepped parameters. Since Bitwig cannot provide the option names, they are labelled Option 1 - Option N.
  * Fixed: Track button states could get inconsisten when tracks were added or removed.
  * Fixed: Parameter mapping did only work for parameters on the first page (did crash for all others). Regression in 25.0.1.
