I’m new to midi control, but I’ve read around the topic and managed to configure QLab to use MIDI note on /off cues to mute and unmute a selected channel. Also fader level control using various velocity numbers. These work OK

The one I can’t crack is the scene change command. Using information from various sources, I’ve tried to activate a scene change by using note on off commands, control change in conjunction with program change and hex data direct into the sysex message. None of these work and when the cues is activated, there is no activity showing in the small send/receive squares at the bottom right of the midi control panel , as there is with the other cues which do work. The detailed instructions imply it SHOULD work, but I can’t fathom what’s wrong ?

QLAB is version 5.6.3 QU16 is version 1.97 rev 4574
