StreamByter: CC High Range Remap with GUI

The following script allows to remap the values of a specific CC. Values higher than a threshold are remapped to a new range.

One of its use-cases is to remap the x-axis of an XY CC controller sending CC-1 vibrato messages to slowly fade in only in the right half of the XY controller and at the same time limit the maximum vibrato depth at the right edge of the XY controller to a specific range.

# === CC High Range Remap ===
# Remaps the range of a single CC. Values higher than
# a threshold are remapped to a new range.
#      Input         Output
#  0 to Threshold      0
#  Threshold to 127    0 to Output Range
