Free MIDI CC transformer

I needed to be able to create a dead spot in the middle of a MIDI slider.
The Cantabile built in curves don’t quite fit the bill.
The best MIDI VST I’ve found for the job is MIDI TRANSFORMER (vst3)

Honourable mentions:
Piz’s midiCurve
The reaJS CC Mapper X

MIDI Transformer is crashing Cantabile upon startup.
