This is modified from the original to support multiple midi channels and play/stop
In this package are two different control scripts, named BeatStep-MidiMapping and BeatStep-NoteInput. Both scripts use an overlay in bitwig to show the values of the mapped knobs. You can turn this of in the corresponding .control.js file. There is a variable SHOW_VALUES, turn it to false and there is no overlay anymore.
With this script, you can map the buttons and the knobs in controller mode.
With this script, you can play the buttons like a keyboard and map the knobs.
If this is your first installation of a controller script, you find here a guide how this works: https://www.bitwig.com/en/community/control_scripts/installation_guide
