I'd like to drive the transition time via OSC, but I can't find it. Is there maybe a list of addresses that are not displayed when you click on them in OSC mapping mode?
0x80O,if you use Vezer to build OSC compositions, make sure you use the new feature "Send normalized value (0.0f-1.0f)" and select a float from 0 to 10 so that you don't have to do calculation to get the float value between 0 and 1 to equate 0 to 10.
Apparently I had scrolled upwards in my layered composition and didn't see layer 1 being lit green in the OSC mapping mode, and clicking the other sliders doesn't show you anything.
It sounds like you were in Layer focus. It might be helpful to read up on Layer and Deck focus, it is an integral part of using Resolume with any external protocol like OSC or Midi.
