I checked the instant mappings I made myself for the Novation Nocturn
(8 encoders, bank forward/backward & lock)
Vocoder: 1st parmeter switches device on/off should be (as with all Live devices): Controls first parameter. It's backwards also.
PingPong Delay: Parameters 1 & 2 (frequency & bandwidth) don't work. (compared with Live7 to be sure)
