Topic: Bug: Entering custom range in MIDI event (Windows)
In the MIDI mappings page, if you are mapping a controller value and select the option "Restrict the value range of ..." in the menu that appears when clicking on the controller value, nothing happens. It is supposed to allow custom ranges to be entered.
Workaround: Right-click on the controller value instead.
I've only seen this happen on the Windows version - the Mac version works ok.
