More information would be good – what controllers, how are your driving them, what are you controlling, etc.

It sounds like you are trying to use a “trigger” (essentially a switch) as a controller.

Hi Nick, thanks for your answer. I am sending a series of CC events from 0 to 127, I tried both from a Midi controller and from a synth and from my step sequencer. So I can confirm that this is happening in the Eclipse and not to do with what I am sending. I tried to map ext1 to ext16 to Midi CCs.
