PabloMartin Thanks Pablo, button issue solved in V3.0.7
However, a different issue:
Assigning a midi CC to MIDI OUT to a 'fader' output works fine, but assigning to MIDI IN value is broken as edit page Value for FADER shows the last touched buttons 'IN' value to all the faders MIDI IN on every page in the template.
Edit: Fader MIDI IN completely broken.
