Hi again all !
See 2 pics below - the first Pic is the Nux Midi CC 6 command and Values List for the SR [Send-Return Block] and the second Pic is from the Editor how I have set it up the SR Block via Midi
The Problem ?
=> When I press the first time to Turn ON the SR Block - it DOES Turn ON => good
=> When I press the second time to Turn OFF the SR Block - it DOES NOT Turn OFF => bad
Any suggestions / help would be greatly appreciated.
