A Kontact script (KSP) that turns pitch bend into a toggleable sustain pedal

I originally wrote this for playing Piano using Native Instruments Maschine without a sustain pedal, but should work with any keyboard with a pitch bend wheel

When enabled, it will intercept pitch bend midi messages as controls for a virtual sustain pedal.
How it works:
Pitch Bend Down - Toggle sustain state on or off permanently
Pitch Bend Up - Temporary inverse of current state

Example use:
Pitch bend down once to toggle always on, then tap pitch bend up whenever you want to mute currently sustained keys (quick lift of pedal)

Installation:
Click the KSP button on the right of the Multi Rack row at the top of Kontakt,
Click edit on one of the empty scripts
Paste in the script
Click Apply
Close Edit by clicking the Edit button again

To Enable: Click the Sustain button at the top of the page then use pitch bend wheel as described above.
